Brain Corp | Multiple positions engineering/operations/product | San Diego CA | Onsite
With 50k robots deployed globally and counting, we're looking for innovators and technologists to help us make the real world work better.
We currently have 13 openings spanning software and QA engineering, technical support, operations and product management.
When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.
We're a global edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.
We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Onsite preferred, but remote candidates with a strong fit are welcome!
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
* The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services.
* Apply: https://www.fastly.com/about/careers
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
At Quobyte we are working on a highly scalable and fault-tolerant software storage system built around a parallel file system core. Our customers use us for large scale AI and HPC clusters in the enterprise and research, k8s and OpenStack infrastructures, and as a scalable backend for SaaS products. There are Quobyte clusters which span tens of thousands of machines and slurp 100s of GB/s!
Under the hood, we have built a full-stack fault-tolerant parallel file system, with everything from kernel development over our own replicated database system design to distributed algorithms (Paxos!) and performance. In short: lots of real-world challenging and fun problems!
We work as a highly efficient engineering team, ship frequently, do code reviews, and have lots of unit and integration testing. If you’re passionate about systems, we might be the right place for you!

Discord | Senior Software Engineer, Application Security | San Francisco, CA | ONSITE | $280K–$330K TC
Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.
We're hiring a Senior Application Security Engineer to join the Product Security team. Responsibilities include threat modeling and secure design review with product and platform teams, building and improving AppSec tooling (SAST/DAST/dependency scanning), and working directly with engineering teams to remediate findings.
Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.

We’ve recently released a series of recordings from one of our quarterly team retreats, to share a look into how we work, and some of the technical problems we’re solving. A few team members sat down and talked through these topics, unscripted, and real. If you consider applying to join us, they offer a glimpse into our culture, and what working with us is really like. Watch the series on YouTube » https://www.youtube.com/@plantingspace9225/videos
(I want to preface that we don't have a ton of budget to expand our team right now and we want to keep the team small, but I also don't want to miss someone who would be a great fit)
We are a self-funded independent AI research lab in Zurich. Currently we explore ARC-AGI3, LLM/RL reasoning, and quant. We recently started a new LLM post-training and pre-training effort, led by some ex-engineers from the swissAI Apertus team. We also like to do some Kaggle on the side, our team includes the top #3 and #12 globally.
Our overall roadmap is to catch up with LLM capabilities, own the full stack, and use it to do our own independent research, pushing efficiency and looking for new paradigms. We expect our new cluster (2x NVL GB300) to be up by the end of the month.
Long term we want to switch to AI alignment/safety research as I believe this is all that matters when AI capability is high enough.
We look for people who are driven, who believe it's possible to make significant contributions to both AI capabilities and safety, and with previous experience pre-training and post-training LLMs and related infra.
If interested, email me at benjamin at tufalabs ai.
Factory | Security Engineer | Onsite in San Francisco | Full-time

Factory builds software development agents that accelerate the world's largest enterprise engineering teams. We're helping customers including Nvidia, Adobe, Adyen, Klarna, and Ernst & Young turn their engineering organizations into autonomous development systems — shipping code, reviewing PRs, running tests, and deploying continuously.
We're seeking a talented Security Engineer to join our team. In this role, you will play a critical role in developing and maintaining the security foundation of our platform. You will conduct in-depth code reviews, implement security best practices, and influence the overall security strategy. Your expertise in TypeScript, Python, Kubernetes, CI/CD, and terraform orchestration will be crucial in identifying and mitigating potential security vulnerabilities.
Great Question is the best way to understand your customers - whether it's mining what they've already told you, or generating new research via interviews, surveys and prototype tests. We're 2nd time founders, closed our Series A last year, with customers from Canva & Brex to Intuit & Amazon.
We're hiring product engineers to help us push the envelope on what's possible in AI engineering practices, while helping our customers bake customer insight into every product release.
You'll do well here if you have a strong sense of what makes a quality product, you're AI native, and you solve the problem of ambiguity with getting closer to customers.
Our group at Yahoo! Search runs the platform that powers AI chat across Yahoo properties (Finance, Sports, News, Search, etc.) as well as our new AI search surface https://scout.yahoo.com/. Lots of fun problems to work on building a high quality grounding data search engine, agentic chat, and our internal knowledge graph -- all at scale with real users.
We are a fully distributed team but work on US time zones. Working environment is somewhere between big tech and startup world, so experience with both would be ideal.
If you're interested, send me your resume at sam.brotherton [at] yahooinc [dot] com

Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time
I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team.
It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people.
This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot.
I‘ve been considering applying at WikiMedia for a while now, but Austria is not in the listed countries. Is there a chance you‘ll expand this list in the future?
Ah, that is too bad. It's certainly always possible the countries list could expand in future, but it's not something I have insight into and unfortunately can't give you too much to go on.
At Middesk, we're building the business identity infrastructure that banks, fintechs, and platforms rely on to know who they're doing business with — powering KYB (Know Your Business) compliance, fraud prevention, and entity verification at scale.

Astoria AI | Founding AI Engineer — Agentic Systems | Remote (async) | Full-time | Equity-only pre-seed, $190k-$280k + equity post-seed
Astoria AI is building an agentic runtime for human potential — a suite of specialized AI agents serving candidates and companies across the entire hiring and talent lifecycle: career strategy, networking intelligence, verified matching, compliance-native hiring, onboarding, and retention.
The hiring market is structurally broken: 44% of resumes contain fabrications, ATS filters reject 88% of qualified candidates, and 27% of posted jobs are ghost jobs — while regulation (EU AI Act, Mobley v. Workday, FCRA suits) is forcing enterprises to rethink hiring AI. We're building the fix.
You'll own the intelligence layer: LLM-powered agentic workflows (tool use, structured outputs, multi-step orchestration), RAG/retrieval pipelines, lightweight ML for classification/ranking/entity matching, and evaluation loops for hallucination risk and output quality.
Looking for: 6+ years professional SW engineering (Python/TypeScript/APIs/DBs), hands-on experience with LLM APIs and agentic workflows, and ideally RAG/embeddings/vector DB experience beyond basic chatbots.
Stage: pre-launch, pre-seed, founding team, equity-only until seed round closes (~4-6 months), then competitive salary + refresh grants.
Apply: Konstantin.mueller@astoria.ai with „HN“ in subject, plus resume or GitHub
> Commenters: please don't reply to job posts to complain about something. It's off topic here.
But also: while I didn't post this, that's not uncommon for a founding engineer. They're looking for someone to help start the company from scratch, typically with a healthy dose of equity. It's a calculated risk for the engineer, possibly worth anywhere from zero to a gazillion dollars depending on outcome.
I normally wouldn't comment, but expecting someone with that skillset and those kind of opportunities available to them to work for free for 4-6 months with the promise of actual pay "when our seed round closes" was so egregious I couldn't help myself, sorry.
At Findigs, we’re transforming the rental experience — making it fairer, stress-free, and more convenient by changing the fundamentals of renting.

Balerion AI | Software + FDE + AI Engineers | San Francisco, CA | ONSITE | Full-time | $250k+ base + seed equity | Visa sponsorship available | https://balerion.ai
We're building agentic AI for mortgage lending — automating document processing and income qualification for loan originators.
Underwriting a loan means pulling numbers out of a few hundred pages of paystubs, W-2s, bank statements, and tax returns, then applying underwriting guidelines that run to thousands of pages of edge cases. Most of it is still done by hand.
Problems we actually work on: routing scanned pages to OCR vs. text extraction when the text layer is unreliable; extraction pipelines where a wrong number is much worse than a missing one; running long agent workflows durably so a failure three steps in doesn't restart the whole loan; and evaluating multi-step output against guidelines that are themselves ambiguous. We put real effort into eval infrastructure, because "the demo looked good" does not survive contact with a lender's compliance team.
Stack: Python, PydanticAI, Restate for durable execution, Postgres, AWS. Frontier models from OpenAI and Anthropic plus open-source models where they win on cost or latency.
We raised an $8M seed led by Kleiner Perkins and have paying customers in production. Team previously at Snowflake, PayPal, Twitter, Atlassian, and Microsoft.
Comp: $250k+ base, meaningful seed-stage equity, 5% 401(k) match, full health coverage, commuter stipend, gym membership, daily office breakfast & lunch. Full relocation to SF covered.
Onsite in SF. Visa sponsorship: yes.
Email vishal@balerion.ai with "HN" in the subject, plus a resume or GitHub.

We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...
You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.
We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.

Seeking US BASED Freelancer Only — Co-Founder - Equity‑only until MVP - Long Term with Follow-on Projects - Remote (US)
Building CaseLight, a local‑first investigative case management and evidence platform for private sector, corporate and insurance investigators. I’m a 24 year former federal LE & current private investigator founder with the full product spec, workflows, and roadmap ready — just need a strong engineer to help punch out the desktop MVP. Front end UI is already operational.
Looking for:
C#/.NET desktop dev, SQLite, local encryption, packaging/installers, clean productivity UI. Must be US‑based. Must be able to ship independently.
Offer: Equity‑only until MVP launch. I have solid GTM, trust network and traction in an otherwise insular market. There is no product like this on the market and the industry is begging for it. Serious builders only.
What you’ll build: case management, evidence ingestion, tagging/search, timeline, encrypted local storage, hashing, dual timestamp, export/report modules.
Drop questions or GitHub + relevant experience to info@getcaselight.com
Six-person venture lab in New York. We build our own products. A studio arm does client work, is profitable, and pays for the rest.
Our founder ran her own design studio and was the founding design partner on Partiful, on Sentropy before Discord bought it, on Goldcast before Cvent, on Make before Celonis, and on Descartes Labs. She builds here now instead of for other people.
You would own the production application around our intelligence layer. Architecture, frontend, backend, Postgres, durable execution state, retries and idempotency, permissions, deploys, and the data-heavy interfaces people work inside all day: tables, relationships, filters, history, approvals. React and TypeScript at depth, Node or Python behind it. We write a lot of MCP servers and build with Claude Code daily.
Seven-plus years shipping, hands on code within the last year. Design and engineering sit in the same room here. There is no handoff.
Most people who apply like the words "founding engineer." We are looking for someone who has already started something of their own.
Ownership. You should own a piece of what you build here. We are not going to post a percentage, because the honest answer depends on what you end up carrying, and we would rather work that out with you than hand you a number that pretends to be precise. It is a conversation, it is flexible, and we intend it to be fair.
We are six people. Nothing you build goes through a committee before it ships. Nothing you break, you fix alone. We are a tight team today and we are looking to double it by the end of the year.
Please send your resume or GitHub, plus the most ambitious thing you have built mostly on your own. Rough work that worked beats polished that never shipped.
If this is not you but a name comes to mind, please pass it along. :)

At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!
We’re hiring for 4 Senior SWEs, 1 MLE and 1 AI PM in SF, and 2 Staff SWEs in NYC. Engineers own projects end-to-end so full stack ability is expected.
I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).
Some examples of how customers get value from Quill:
• pre-IPO fintech adds custom reporting & data export features to their money movement product.
• Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard.
• Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.
Reasons you’d love working with us:
• Work with a small, focused, talented team on a highly technical product (by developers for developers).
• Funded company in a big market, but still prelaunch with a team size <5
• High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).
We build environments that frontier AI labs use to train their models to do real-world software engineering. We have more demand than we can keep up with, so we're hiring fast.
It’s so interesting that the example training given is game boy advance emulator as such a large task, when misalignments and task veering happen so regularly in smaller bits.

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation
- A double-entry ledger where balance is derived and no client write can change it
- Server-side enforcement of every limit and refusal
- Payment rails idempotent under duplicated webhooks
- Seed custody and the provably-fair lifecycle
- An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.

Modash helps brands find, manage, and pay creators - and helps creators earn a living.
The product looks simple on the surface. Underneath, we index 380M+ public creator profiles across Instagram, TikTok, and YouTube so that 1,700+ brands search, evaluate, manage, and pay creators without drowning in spreadsheets and tabs.
We're looking for Senior Product Engineers who like owning ambiguous problems end-to-end. No perfectly shaped tickets. You talk to customers, understand messy workflows, make product decisions, ship, and own whether it actually works.
The problems we care about:
- How do you make a 380M-profile dataset feel fast, trustworthy, and easy to explore?
- How do you turn chaotic influencer marketing workflows into product that feels obvious?
- How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're 85 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe.
No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.

Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Tufalabs | Zurich, ONSITE | Full-time | 100-200k CHF | https://tufalabs.ai/
(I want to preface that we don't have a ton of budget to expand our team right now and we want to keep the team small, but I also don't want to miss someone who would be a great fit)
We are a self-funded independent AI research lab in Zurich. Currently we explore ARC-AGI3, LLM/RL reasoning, and quant. We recently started a new LLM post-training and pre-training effort, led by some ex-engineers from the swissAI Apertus team. We also like to do some Kaggle on the side, our team includes the top #3 and #12 globally.
Our overall roadmap is to catch up with LLM capabilities, own the full stack, and use it to do our own independent research, pushing efficiency and looking for new paradigms. We expect our new cluster (2x NVL GB300) to be up by the end of the month.
Long term we want to switch to AI alignment/safety research as I believe this is all that matters when AI capability is high enough.
We look for people who are driven, who believe it's possible to make significant contributions to both AI capabilities and safety, and with previous experience pre-training and post-training LLMs and related infra.
If interested, email me at benjamin at tufalabs ai.

Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time
I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team.
It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people.
This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot.
You can apply at https://job-boards.greenhouse.io/wikimedia/jobs/8140060?gh_s... - we don’t auto-filter based on AI or anything like that, I will personally see your resume.
I‘ve been considering applying at WikiMedia for a while now, but Austria is not in the listed countries. Is there a chance you‘ll expand this list in the future?
Ah, that is too bad. It's certainly always possible the countries list could expand in future, but it's not something I have insight into and unfortunately can't give you too much to go on.

Astoria AI | Founding AI Engineer — Agentic Systems | Remote (async) | Full-time | Equity-only pre-seed, $190k-$280k + equity post-seed
Astoria AI is building an agentic runtime for human potential — a suite of specialized AI agents serving candidates and companies across the entire hiring and talent lifecycle: career strategy, networking intelligence, verified matching, compliance-native hiring, onboarding, and retention.
The hiring market is structurally broken: 44% of resumes contain fabrications, ATS filters reject 88% of qualified candidates, and 27% of posted jobs are ghost jobs — while regulation (EU AI Act, Mobley v. Workday, FCRA suits) is forcing enterprises to rethink hiring AI. We're building the fix.
You'll own the intelligence layer: LLM-powered agentic workflows (tool use, structured outputs, multi-step orchestration), RAG/retrieval pipelines, lightweight ML for classification/ranking/entity matching, and evaluation loops for hallucination risk and output quality.
Looking for: 6+ years professional SW engineering (Python/TypeScript/APIs/DBs), hands-on experience with LLM APIs and agentic workflows, and ideally RAG/embeddings/vector DB experience beyond basic chatbots.
Stage: pre-launch, pre-seed, founding team, equity-only until seed round closes (~4-6 months), then competitive salary + refresh grants.
Apply: Konstantin.mueller@astoria.ai with „HN“ in subject, plus resume or GitHub
Wow.
You expect an AI Engineer to work essentially for free for 4-6 months?
> Commenters: please don't reply to job posts to complain about something. It's off topic here.
But also: while I didn't post this, that's not uncommon for a founding engineer. They're looking for someone to help start the company from scratch, typically with a healthy dose of equity. It's a calculated risk for the engineer, possibly worth anywhere from zero to a gazillion dollars depending on outcome.
I normally wouldn't comment, but expecting someone with that skillset and those kind of opportunities available to them to work for free for 4-6 months with the promise of actual pay "when our seed round closes" was so egregious I couldn't help myself, sorry.

Apex Space | Multiple Roles | Full-Time | Onsite | Los Angeles, CA | apexspace.com
Apex Space is building standardized spacecraft platforms to enable true mass-production of spacecraft and enabling getting varied and similarly mass-produced payloads to orbit.

Balerion AI | Software + FDE + AI Engineers | San Francisco, CA | ONSITE | Full-time | $250k+ base + seed equity | Visa sponsorship available | https://balerion.ai
We're building agentic AI for mortgage lending — automating document processing and income qualification for loan originators.
Underwriting a loan means pulling numbers out of a few hundred pages of paystubs, W-2s, bank statements, and tax returns, then applying underwriting guidelines that run to thousands of pages of edge cases. Most of it is still done by hand.
Problems we actually work on: routing scanned pages to OCR vs. text extraction when the text layer is unreliable; extraction pipelines where a wrong number is much worse than a missing one; running long agent workflows durably so a failure three steps in doesn't restart the whole loan; and evaluating multi-step output against guidelines that are themselves ambiguous. We put real effort into eval infrastructure, because "the demo looked good" does not survive contact with a lender's compliance team.
Stack: Python, PydanticAI, Restate for durable execution, Postgres, AWS. Frontier models from OpenAI and Anthropic plus open-source models where they win on cost or latency.
We raised an $8M seed led by Kleiner Perkins and have paying customers in production. Team previously at Snowflake, PayPal, Twitter, Atlassian, and Microsoft.
Comp: $250k+ base, meaningful seed-stage equity, 5% 401(k) match, full health coverage, commuter stipend, gym membership, daily office breakfast & lunch. Full relocation to SF covered.
Onsite in SF. Visa sponsorship: yes.
Email vishal@balerion.ai with "HN" in the subject, plus a resume or GitHub.
InfoHawk | Software Engineer | London, UK or NYC | REMOTE (UK or US), occasional onsite | Full-time | https://www.infohawk.com
Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...
You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.
We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.

ODK | Senior Product Manager | Remote (Worldwide) | Long-term contract, 30–40 hours/week | $90–$110/hour USD
ODK is an open-source platform used by thousands of organizations worldwide to collect billions of data points for disease surveillance, supply chain traceability, environmental monitoring, and more. It enables users to build powerful forms and reliably collect structured data, even in places with little or no Internet connectivity.
ODK has been actively developed for 18 years. We have a mix of self-hosted and SaaS users across many sectors. We're looking for a senior product manager who will own product discovery and prioritization across this diverse user base. To be successful, you'll need to find the common needs behind very different workflows and turn them into opinionated product improvements.
Because the team is small and the user base is large, this is a high-autonomy role where product decisions have an unusually direct impact. You should have substantial experience managing complex B2B or technical products. Experience with open source, self-hosted software, and small, fully remote teams is a plus.

Seeking US BASED Freelancer Only — Co-Founder - Equity‑only until MVP - Long Term with Follow-on Projects - Remote (US)
Building CaseLight, a local‑first investigative case management and evidence platform for private sector, corporate and insurance investigators. I’m a 24 year former federal LE & current private investigator founder with the full product spec, workflows, and roadmap ready — just need a strong engineer to help punch out the desktop MVP. Front end UI is already operational.
Looking for: C#/.NET desktop dev, SQLite, local encryption, packaging/installers, clean productivity UI. Must be US‑based. Must be able to ship independently.
Offer: Equity‑only until MVP launch. I have solid GTM, trust network and traction in an otherwise insular market. There is no product like this on the market and the industry is begging for it. Serious builders only.
What you’ll build: case management, evidence ingestion, tagging/search, timeline, encrypted local storage, hashing, dual timestamp, export/report modules.
Drop questions or GitHub + relevant experience to info@getcaselight.com
Sunspell | Founding Engineer | New York, NY | ONSITE | Full-time | https://sunspell.fm/careers/founding-engineer
Six-person venture lab in New York. We build our own products. A studio arm does client work, is profitable, and pays for the rest.
Our founder ran her own design studio and was the founding design partner on Partiful, on Sentropy before Discord bought it, on Goldcast before Cvent, on Make before Celonis, and on Descartes Labs. She builds here now instead of for other people.
You would own the production application around our intelligence layer. Architecture, frontend, backend, Postgres, durable execution state, retries and idempotency, permissions, deploys, and the data-heavy interfaces people work inside all day: tables, relationships, filters, history, approvals. React and TypeScript at depth, Node or Python behind it. We write a lot of MCP servers and build with Claude Code daily.
Seven-plus years shipping, hands on code within the last year. Design and engineering sit in the same room here. There is no handoff.
Most people who apply like the words "founding engineer." We are looking for someone who has already started something of their own.
Ownership. You should own a piece of what you build here. We are not going to post a percentage, because the honest answer depends on what you end up carrying, and we would rather work that out with you than hand you a number that pretends to be precise. It is a conversation, it is flexible, and we intend it to be fair.
We are six people. Nothing you build goes through a committee before it ships. Nothing you break, you fix alone. We are a tight team today and we are looking to double it by the end of the year.
Please send your resume or GitHub, plus the most ambitious thing you have built mostly on your own. Rough work that worked beats polished that never shipped.
If this is not you but a name comes to mind, please pass it along. :)

Renaissance Philanthropy | Research Engineer (Speech AI/ML) | Remote (worldwide)
Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments.
RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years.
We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student.
We're looking for folks who:
- have built and operated production ASR or speech-processing systems
- know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment
- can speak the languages of both research and engineering
- want to help create a world where all children learn to read well.

Shepherd (Series B) | ONSITE | San Francisco, CA
At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!
We’re hiring for 4 Senior SWEs, 1 MLE and 1 AI PM in SF, and 2 Staff SWEs in NYC. Engineers own projects end-to-end so full stack ability is expected.
Check out our open roles here: https://shepherdinsurance.com/careers
Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis
– If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.
* In the form, be sure to mention that you heard about this opportunity via Hacker News.

Quill | Fullstack SWE | Full-time | Remote, PT/ET hours preferred | $150 - 210K USD + equity | https://quill.co/
I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).
Some examples of how customers get value from Quill: • pre-IPO fintech adds custom reporting & data export features to their money movement product. • Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard. • Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.
Reasons you’d love working with us: • Work with a small, focused, talented team on a highly technical product (by developers for developers). • Funded company in a big market, but still prelaunch with a team size <5 • High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation - A double-entry ledger where balance is derived and no client write can change it - Server-side enforcement of every limit and refusal - Payment rails idempotent under duplicated webhooks - Seed custody and the provably-fair lifecycle - An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.

DAT | Frontline Engineering Manager, Senior Engineering Manager | Seattle, Portland, Denver | Hybrid 2-3 days/week | Full-time | $192k - $261k
I'm hiring for a frontline EM building the automation and trust layer for freight pricing, matching, onboarding, and settlement.Lead 1-3 teams (FTE + contractors), own delivery end-to-end, ~8 yrs exp typical. I expect everyone in my eng org (myself included!) to be technical and be able to help unblock the team, though your day-to-day wont be in the code.
Technical here means you can/will get into the code yourself and architecture reviews and maintain technical credibility with our junior to staff/principal level engineers. These are not player-coach roles, but these are frontline roles that need that technical capability.
Interesting problems: trust/fraud at marketplace scale; legacy-data-meets-modern-stack; and all kinds of problems that come with powering hundreds of thousands of load/shipment postings every day.
AI/LLM: We are leaned in, but still hold humans responsible for what they push and expect everyone to review and understand llm output before asking other humans to look at a thing.
Culture: I am deeply familiar with Google's project oxygen/aristotle and am building a culture where our teams can do great work with minimal bs.
Location: Must be local to one of our three locations (Seattle, Portland, Denver).
Primary Tech: Node/TS, React, GraphQL, Kafka/redpanda, k8s, AWS, etc

The problems we care about:

- How do you turn chaotic influencer marketing workflows into product that feels obvious?
- How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're 85 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe. No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.

howdy! This is the "Who's hiring?" post, I believe you're looking for the "Who wants to be hired?" post
Stpkr Technologies | Noida, India (Delhi NCR) | ONSITE | Multiple roles
Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now. Thanks for your time!
