Caribou | Toronto| Full Time | Hybrid (one day in office) | https://www.caribou.care/
Caribou helps homecare organizations attract, engage, and retain staff through data-driven recognition, rewards, and coordination tools that make the lives of patients and their caregivers better. We're a small company of ~50 people who are mostly based in the GTA.
We are building on our core product such as deploying AI-powered agentic systems that work alongside agency coordinators to handle routine coordination, outreach, and administrative workflows to improve agency operations.
I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.
Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).
The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.
You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.
We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.
PrairieLearn (https://www.prairielearn.com) is an open-source assessment platform used by universities across the US (Berkeley, Princeton, Michigan, Illinois, and others). We power mastery-based learning and large-scale exams.
We’re a small, profitable, early-stage company (bootstrapped, no VC) that is growing quickly. Our users love us and we have very high retention and rapid spread through word of mouth. As an early-stage hire, you’ll work across the stack and enjoy meaningful ownership from day one.
Tech we use: Node.js / TypeScript backend, Postgres, AWS, React. We’re also developing AI tooling, including building LLM agents to help instructors create content and using vision-language models to help grade student work. PrairieLearn is open core: https://github.com/PrairieLearn/PrairieLearn
Gulid.ai is the control plane for agents. We're building a new way of orchestrating and sharing agents that mimics some of the best parts of Github, with the centralized control and credential management that enterprise shops need.
From our about us: We are builders at heart—founders, SREs, open-source stewards, architects of large systems, and people who love creating things from scratch. We believe AI should amplify the creativity of everyone who builds software, not just speed up tasks. If you’re technical, curious, customer-driven, and want to shape how the next generation of software is created, we’d be thrilled to work with you.
We have multiple open roles, including AI Engineer, Forward Deployed Engineer, and Software Engineers.
Everflow is a SaaS Partner Marketing platform for managing and scaling revenue from affiliates, partnerships, and marketing channels. We're 10 years in, profitable, no outside funding
The stack : Java, Angular (Typescript), Go, MySQL, Redis. We're a GCP shop and make heavy use of Pub/Sub, BigQuery, BigTable and Kubernetes (GKE)
We're looking for software engineers and / or senior software engineers (at least 3 years) with some hands on experience to join the growing (~15 devs / SREs) team and help us build the product. We don't have a specific profile in mind but you have a track record of shipping, are interested in architecture / care about the craft and are comfortable in a no-downtime environment.
Sony Music Entertainment | London, UK / New York, NY | ONSITE / HYBRID
Sony Music Entertainment is one of the world's leading music companies, home to artists, labels, and the technology that powers them. We're hiring across engineering and product.
Datadog is a monitoring, tracing, logs system, and more, for your infrastructure and services. We build our own tsdb, event store [1][2], distributed tracing tools, cutting edge visualizations, and more. We love shipping great experiences for customers just like us and are growing fast! We write a lot of Go, Java, Python, Typescript (with React), and a bit of other languages. We run on k8s, and are multi-region and multi-cloud.
We're looking for people who can build systems at scale as we process trillions of events per day. Let us know if that's you!
Fusionbox | Python + TypeScript Engineers | United States | Full-time | REMOTE (US)
We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect race conditions.
A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll work with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
Neurotone.ai || Remote (Americas East / Western Europe) || Full-time || neurotone.com
We build AI-assisted auditory training for people with hearing loss. Our product is live, in clinics, and growing internationally.
Backend Engineer: Postgres-heavy work on Supabase: PL/pgSQL functions, pgmq queues, Deno edge functions, billing and cron systems. You like databases enough to enjoy writing triggers and RLS policies, and you want to own systems end-to-end rather than just ship tickets.
QA Specialist: Manual testing of our iOS/Android app and web tools, working alongside our head of QA on a clinical product where data quality, platform stability, and accessibility are critical to our mission.
Note: Candidates must be in time zones no further west than EST; Western Europe is fine.
If interested, contact travis AT neurotone.com. Join us in making a difference!

- Real users, real impact, high autonomy
- Fast, fair interview loop — no BS
- Fully covered healthcare for you and your dependents
We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.
We’re building out our team in the following areas:
We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users.

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.
Must be authorized to work in the US. We’ll evaluate submissions for two weeks.
Email steven@kanary.com with something you've built and why it was hard.
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 globally edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.

If that sounds interesting, we'd welcome a conversation.
Hotwash | Founding Engineer (→ CTO for the right person) | REMOTE (US), Boston a plus | Full-time
I'm a solo founder. I built the entire product myself, got 11 fire departments paying with zero churn, and now I need someone to own engineering so I can't be the only one who does. West Point, Ranger Regiment, Yale Law, still the only developer.
What we do: Hotwash is an after-action review platform for fire departments. After a serious call, crews record what happened, we transcribe and structure it, and the hard-won lessons become searchable institutional memory instead of retiring when the veterans who earned them do. Fire is the wedge; the long game is operational learning for any high-reliability organization.
Traction: $40K ARR, 11 paying fire departments, zero churn. Raising a $1M pre-seed.
The role: Employee #1 on engineering. You own the codebase, architecture, and UX end to end, and you lead the rebuild off the current stack. You work directly with me on what gets built and why, including sitting with fire chiefs to figure out what they actually need. For the right person this becomes the CTO seat.
Who I'm looking for: A full-stack engineer who ships simple, usable products and has a real eye for design. Our users are fire crews, not power users, so the bar is "obvious to someone who's never seen it." If you care about how software feels, not just whether it works, this is your seat.
Stack: Today it's FlutterFlow + Firebase, Node, with Groq/AssemblyAI for transcription and Gemini for summarization. The rebuild target is React Native (Expo), Cloudflare Workers, D1, R2. You'd own that migration, so this is real greenfield ownership, not maintenance.
Comp: Founding equity, scaled to scope.
We're pre-raise, so cash is lean right now and grows when we close.
Email hiring@hotwash.com with a resume, link to something you've built, and one line on why this interests you.

We're VC backed, profitable, and have plenty of ambition to maintain our fast growth in this absolutely massive market.
SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.
Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.
We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.
In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.
We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~500). Now we’re scaling the platform.
Kind, smart, low-drama people, seeking the same to help make writing tools authors dream about.

Emergences Labs (emergences.ai) | AI / Systems Engineer — NeoHuman | REMOTE (US) | Full-time | $120K-$150K + equity | Visa sponsorship available
We're a small, research-driven, VC-backed team building NeoHuman: a desktop-first system that observes how people actually use AI tools, files, and workflows during real tasks, and turns those sessions into reliable evaluation evidence. We care about the process, not just the final answer — what someone typed, what they copied, what they verified, how they moved across apps.
We've published the AgentIF-OneDay benchmark. Now we're scaling the capture and evaluation infrastructure underneath it.
You'd own:
- Cross-platform desktop capture across macOS + Windows (AX/UIA trees, OCR, clipboard, keyboard/mouse boundaries, file interactions)
- Trace fusion — turning noisy low-level signals into clean human-readable session timelines
- The evaluation evidence pipeline (data model, ingestion, exports)
- LLM normalization that summarizes traces without hallucinating or hiding evidence quality
- Privacy/consent/proctoring safety for enterprise customers
We want an AI-native engineer:
- 3+ years shipping production TypeScript + Node.js
- Built or shipped Electron + native helpers
- Strong PostgreSQL (schema design, indexing, data quality)
- Comfortable with OS APIs, permissions, background processes
- Hands-on LLM API experience (structured output, evaluation, hallucination control)
- Uses Claude Code, Cursor, or similar as a daily working medium — not a side experiment
- Bonus: macOS AX / ScreenCaptureKit / CGEventTap, Windows UIA, or you've studied/built things like Screenpipe, OpenAdapt, Rewind, OpenChronicle
Why us: Hard, unusual problem at the boundary of OS internals, multimodal capture, and AI evaluation. Small team, technical founders who code daily, real ownership of the capture stack. We hire on demonstrated capability, not credentials.
Apply: email jack@emergences.ai with your resume and a brief note about a system you've built — desktop software, AI infra, data pipelines, evaluation, or low-level debugging. Subject: "Your Name — AI / Systems Engineer". Please mention HN in the email.

Roles
Senior AI Engineer | $180k-220k: Own end-to-end LLM product surfaces in a clinical/HIPAA environment, running rigorous evals and experiments across prompts, retrieval, and agents while shipping fast with strong Python chops and NLP fundamentals.
Senior Software Engineer, Scribe & Integrations | $160k-190k: Ship production React Native apps with strong TypeScript/PostgreSQL chops to own the full stack end-to-end, wrangling messy EHR data integrations and turning fuzzy clinical workflows into fast-shipped, observable features.
Senior Software Engineer, Platform | $160k-190k: Stack - Python (FastAPI/Django/Flask), React, PostgreSQL, and AWS to own platform architecture and IC delivery on a small team while mentoring engineers and setting the quality bar across a fast-moving healthcare codebase.
Requirements for all roles: 5+ YoE | Startup experience | Auth to work in US
I'm building an AI-native operations tool for private mortgage lenders. MVP targets two workflows that eat servicing staff time: NSF collections follow-up and renewal management. I run a Canadian private lender as my day job, so the product is built against a real shop with real data and real users. Self-funded. No VCs, no board.
The data model is locked (20 tables, multi-tenant by lender_id, idempotent CSV imports, append-only event log). Wireframes in progress. Hiring one engineer for the full ~6-month build via a paid bake-off: $5k flat for ~1 week of work, 2-3 candidates in parallel, winner takes the engagement. Losing candidates get paid in full and keep their work.
Trial scope: CSV loan tape import with idempotent upsert + audit, one case detail screen, one LLM call classifying a borrower email reply with structured output, activity log driven by case events. Stack is contractor's choice — Postgres required, Next.js + TS or Python + React expected.
Looking for senior generalists with real production LLM experience (structured outputs, evals, failure modes — not side-project tier) and strong relational data modeling judgment. Opinions you'll defend in writing.
Email: info@readifinancial.com
with: one paragraph on why this interests you, 1-2 links to shipped work involving a real schema + LLM in production, your rate and availability, and one question about the project. No cover letters.

*Scribd | Lead Product Manager, AI Developer Platform | US, Canada | REMOTE*
Scribd, Inc. is on a mission to advance human understanding. Our four products — Scribd®, Slideshare®, Everand™, and Fable — help billions of people across the globe move beyond access and into insight, application, and expertise. We're a YC '06 company — one of the oldest still around — running one of the largest Ruby on Rails sites, serving 200M+ unique visitors a month with 2M+ paying subscribers.
I'm hiring a PM to own our *AI Developer Platform* — the internal product 200+ engineers build on every day. The platform spans the full agentic stack: the tools in each engineer's hands (Claude Code), a plugin marketplace and a library of skills that extend them, an internal app platform and agent runtime that teams build on, and the evals, canonical context, and conventions that make agents reliable across a polyglot codebase (Ruby, Go, TypeScript, Python; AWS/Databricks). You'll own the product strategy for developer experience and how we measure it, partnering directly with the Developer Platform and Data Platform engineering teams who build the underlying capabilities.
We're looking for a highly technical PM — quite possibly a former engineer — who is genuinely passionate about how developer platforms are evolving in the age of AI. You've shipped real products with modern agentic primitives (agents, evals, tool use, MCP, plugins/skills), and you can hold your own with engineers in technical discussions.

Friendly, people-first, engineering-driven culture with competitive salary, great benefits, and real work-life balance.
Kepler | Full Stack Engineer | New York, NY | ONSITE | $230K-$260K + equity
We're building the trust layer for AI in high-stakes industries. https://kepler.ai
LLMs hallucinate, so they can't be the thing producing your numbers. In Kepler, the LLM orchestrates (decides what data to gather, what to compute, how to structure the output), but the model never touches the data itself. Every actual value flows through deterministic code pipelines with provenance metadata back to source. Verification loops cross-check outputs before users see them.
We started in finance because tolerance for wrong answers is zero. First product is a research platform for buy-side analysts: pull comparables, build models, research filings. Same architecture extends to chemicals, legal, healthcare. Models are commoditizing fast; the trust layer is what's missing.
- Source-explorer UI that traces any value back to its exact origin in the original document - Extraction pipeline for a data source we don't yet handle, with provenance and verification from day one - Agent orchestrator that handles partial failures so a bad extraction from one source doesn't block parallel work - Verification rules that cross-check values across multiple sources and surface conflicts with provenance on both sides
Stack: Rust backend (orchestration, extraction, computation), TypeScript/React frontend, PostgreSQL, AWS. Model-agnostic, currently Claude + GPT. We don't require Rust experience; we hire on fundamentals.
Looking for 5 years production experience, strong in TypeScript/React, comfortable in backend work. Bonus if you've built systems where correctness mattered (payments, data infra, healthcare, anything where a wrong output has consequences). Distributed systems basics: concurrency, fault tolerance, retries, idempotency.
Founding team is 40+ combined years at Palantir building Foundry's core systems (Ontology, Fusion, Workshop, FoundryML). CEO scaled a data company to $15M ARR, sold it, then ran Business Engineering at Citadel. Backed by founders of OpenAI, Meta AI Research, MotherDuck, dbt Labs.
MixRank processes petabytes of data every month through web crawling. Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.
Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests.
Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.
We’re looking for remote junior engineers with 0–3 years of professional software experience and 5+ years of curiosity exploring computers, programming, and technical hobby projects.
This is an open-ended entry role with mentorship and diverse opportunities to work across all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more.
To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, or anything else that shows how you think and build.
Ideally, you’ve already graduated. But if you still have one or more years left of school, please feel free to apply anyway. If you’re the right fit for the team, we’ll figure out a way to accommodate your schedule.
We’re hiring generalist software engineers to work on web applications, data mining, machine learning/data science, data transformation/ETL, data modeling, database scaling, infrastructure, DevOps, and more. We’ll tailor the role to the subset of areas that best match your interests.
Beneficial experience includes PostgreSQL, Python, Rust, Linux, TypeScript, Nix, frontend/backend web development, and data mining.
I’m Kiran, Chief of Staff at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
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 just recently announced our $42M Series B! 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.
This year, we’re growing our engineering team from 25 to 40. We’re looking for product-minded engineers to join us as we continue to scale! We’re looking for someone who thrives on ownership, drives results, and cares deeply about both technical excellence and customer impact.
We’re hiring various mid-level, senior-level and staff-level engineers. See some of our openings below:

Chestnut | Senior Product Engineer | SF or Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut
I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.
Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).
The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.
You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.
We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

Fusionbox | Python + TypeScript Engineers | United States | Full-time | REMOTE (US)
We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect race conditions.
A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll work with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

Backend Engineer: Postgres-heavy work on Supabase: PL/pgSQL functions, pgmq queues, Deno edge functions, billing and cron systems. You like databases enough to enjoy writing triggers and RLS policies, and you want to own systems end-to-end rather than just ship tickets.
QA Specialist: Manual testing of our iOS/Android app and web tools, working alongside our head of QA on a clinical product where data quality, platform stability, and accessibility are critical to our mission.
Note: Candidates must be in time zones no further west than EST; Western Europe is fine.

Kanary | Full Stack Engineer | Remote (US) | Competitive Salary + Equity | Python / React
Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.

Hotwash | Founding Engineer (→ CTO for the right person) | REMOTE (US), Boston a plus | Full-time
I'm a solo founder. I built the entire product myself, got 11 fire departments paying with zero churn, and now I need someone to own engineering so I can't be the only one who does. West Point, Ranger Regiment, Yale Law, still the only developer.
What we do: Hotwash is an after-action review platform for fire departments. After a serious call, crews record what happened, we transcribe and structure it, and the hard-won lessons become searchable institutional memory instead of retiring when the veterans who earned them do. Fire is the wedge; the long game is operational learning for any high-reliability organization.
Traction: $40K ARR, 11 paying fire departments, zero churn. Raising a $1M pre-seed.
The role: Employee #1 on engineering. You own the codebase, architecture, and UX end to end, and you lead the rebuild off the current stack. You work directly with me on what gets built and why, including sitting with fire chiefs to figure out what they actually need. For the right person this becomes the CTO seat.
Who I'm looking for: A full-stack engineer who ships simple, usable products and has a real eye for design. Our users are fire crews, not power users, so the bar is "obvious to someone who's never seen it." If you care about how software feels, not just whether it works, this is your seat.
Stack: Today it's FlutterFlow + Firebase, Node, with Groq/AssemblyAI for transcription and Gemini for summarization. The rebuild target is React Native (Expo), Cloudflare Workers, D1, R2. You'd own that migration, so this is real greenfield ownership, not maintenance.
Comp: Founding equity, scaled to scope.
We're pre-raise, so cash is lean right now and grows when we close.
Email hiring@hotwash.com with a resume, link to something you've built, and one line on why this interests you.

SmarterDx | 150-250k+ + equity + benefits | Remote (US only) | Multiple roles | https://smarterdx.com/careers
SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.
Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.
We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.
In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.
We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~500). Now we’re scaling the platform.

Starbridge | Senior Engineers (Kotlin/Java/React/Typescript) | NYC or Remote | Full-time |
[starbridge.ai](https://www.google.com/url?q=http://starbridge.ai&sa=D&sourc...)
Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.
Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.
AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.
Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.
We're looking to build our in-person team in NYC but also open to remote!

Emergences Labs (emergences.ai) | AI / Systems Engineer — NeoHuman | REMOTE (US) | Full-time | $120K-$150K + equity | Visa sponsorship available
We're a small, research-driven, VC-backed team building NeoHuman: a desktop-first system that observes how people actually use AI tools, files, and workflows during real tasks, and turns those sessions into reliable evaluation evidence. We care about the process, not just the final answer — what someone typed, what they copied, what they verified, how they moved across apps.
We've published the AgentIF-OneDay benchmark. Now we're scaling the capture and evaluation infrastructure underneath it.
You'd own: - Cross-platform desktop capture across macOS + Windows (AX/UIA trees, OCR, clipboard, keyboard/mouse boundaries, file interactions) - Trace fusion — turning noisy low-level signals into clean human-readable session timelines - The evaluation evidence pipeline (data model, ingestion, exports) - LLM normalization that summarizes traces without hallucinating or hiding evidence quality - Privacy/consent/proctoring safety for enterprise customers
We want an AI-native engineer: - 3+ years shipping production TypeScript + Node.js - Built or shipped Electron + native helpers - Strong PostgreSQL (schema design, indexing, data quality) - Comfortable with OS APIs, permissions, background processes - Hands-on LLM API experience (structured output, evaluation, hallucination control) - Uses Claude Code, Cursor, or similar as a daily working medium — not a side experiment - Bonus: macOS AX / ScreenCaptureKit / CGEventTap, Windows UIA, or you've studied/built things like Screenpipe, OpenAdapt, Rewind, OpenChronicle
Stack: TypeScript · Node.js · Electron · native macOS/Windows · Next.js 15 · React 19 · Postgres + Supabase · OCR · Accessibility APIs · OpenAI / Anthropic / Gemini · Vercel · GitHub Actions
Why us: Hard, unusual problem at the boundary of OS internals, multimodal capture, and AI evaluation. Small team, technical founders who code daily, real ownership of the capture stack. We hire on demonstrated capability, not credentials.
Apply: email jack@emergences.ai with your resume and a brief note about a system you've built — desktop software, AI infra, data pipelines, evaluation, or low-level debugging. Subject: "Your Name — AI / Systems Engineer". Please mention HN in the email.

Servicing Copilot | Senior Full-Stack Contractor | REMOTE (EST overlap required) | $5k paid bake-off → ~6 month contract | CAD $130-180/hr
I'm building an AI-native operations tool for private mortgage lenders. MVP targets two workflows that eat servicing staff time: NSF collections follow-up and renewal management. I run a Canadian private lender as my day job, so the product is built against a real shop with real data and real users. Self-funded. No VCs, no board.
The data model is locked (20 tables, multi-tenant by lender_id, idempotent CSV imports, append-only event log). Wireframes in progress. Hiring one engineer for the full ~6-month build via a paid bake-off: $5k flat for ~1 week of work, 2-3 candidates in parallel, winner takes the engagement. Losing candidates get paid in full and keep their work.
Trial scope: CSV loan tape import with idempotent upsert + audit, one case detail screen, one LLM call classifying a borrower email reply with structured output, activity log driven by case events. Stack is contractor's choice — Postgres required, Next.js + TS or Python + React expected.
Looking for senior generalists with real production LLM experience (structured outputs, evals, failure modes — not side-project tier) and strong relational data modeling judgment. Opinions you'll defend in writing.
Email: info@readifinancial.com
with: one paragraph on why this interests you, 1-2 links to shipped work involving a real schema + LLM in production, your rate and availability, and one question about the project. No cover letters.
Search terms: postgres, multi-tenant, LLM, OpenAI, Anthropic, Next.js,

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 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!

hi, can you add more context!
*Scribd | Lead Product Manager, AI Developer Platform | US, Canada | REMOTE*
Scribd, Inc. is on a mission to advance human understanding. Our four products — Scribd®, Slideshare®, Everand™, and Fable — help billions of people across the globe move beyond access and into insight, application, and expertise. We're a YC '06 company — one of the oldest still around — running one of the largest Ruby on Rails sites, serving 200M+ unique visitors a month with 2M+ paying subscribers.
I'm hiring a PM to own our *AI Developer Platform* — the internal product 200+ engineers build on every day. The platform spans the full agentic stack: the tools in each engineer's hands (Claude Code), a plugin marketplace and a library of skills that extend them, an internal app platform and agent runtime that teams build on, and the evals, canonical context, and conventions that make agents reliable across a polyglot codebase (Ruby, Go, TypeScript, Python; AWS/Databricks). You'll own the product strategy for developer experience and how we measure it, partnering directly with the Developer Platform and Data Platform engineering teams who build the underlying capabilities.
We're looking for a highly technical PM — quite possibly a former engineer — who is genuinely passionate about how developer platforms are evolving in the age of AI. You've shipped real products with modern agentic primitives (agents, evals, tool use, MCP, plugins/skills), and you can hold your own with engineers in technical discussions. This is the first PM seat at Scribd pointed inward, in a brand-new domain with no playbook to inherit. Reports to me (Director, Developer Platform).
Friendly, people-first, engineering-driven culture with competitive salary, great benefits, and real work-life balance.
Apply: https://jobs.ashbyhq.com/ScribdInc/ff2680ea-9a6d-436d-bdb0-3... — or email me directly at cktaylor at scribd.com (I've hired off these threads before). Recruiters/agencies, please don't.
Kepler | Full Stack Engineer | New York, NY | ONSITE | $230K-$260K + equity We're building the trust layer for AI in high-stakes industries. https://kepler.ai
LLMs hallucinate, so they can't be the thing producing your numbers. In Kepler, the LLM orchestrates (decides what data to gather, what to compute, how to structure the output), but the model never touches the data itself. Every actual value flows through deterministic code pipelines with provenance metadata back to source. Verification loops cross-check outputs before users see them.
We started in finance because tolerance for wrong answers is zero. First product is a research platform for buy-side analysts: pull comparables, build models, research filings. Same architecture extends to chemicals, legal, healthcare. Models are commoditizing fast; the trust layer is what's missing.
If you want the deeper architecture writeup, Anthropic just published a case study on Kepler: https://claude.com/blog/how-kepler-built-verifiable-ai-for-f...
What you'd build:
- Source-explorer UI that traces any value back to its exact origin in the original document - Extraction pipeline for a data source we don't yet handle, with provenance and verification from day one - Agent orchestrator that handles partial failures so a bad extraction from one source doesn't block parallel work - Verification rules that cross-check values across multiple sources and surface conflicts with provenance on both sides
Stack: Rust backend (orchestration, extraction, computation), TypeScript/React frontend, PostgreSQL, AWS. Model-agnostic, currently Claude + GPT. We don't require Rust experience; we hire on fundamentals.
Looking for 5 years production experience, strong in TypeScript/React, comfortable in backend work. Bonus if you've built systems where correctness mattered (payments, data infra, healthcare, anything where a wrong output has consequences). Distributed systems basics: concurrency, fault tolerance, retries, idempotency.
Founding team is 40+ combined years at Palantir building Foundry's core systems (Ontology, Fusion, Workshop, FoundryML). CEO scaled a data company to $15M ARR, sold it, then ran Business Engineering at Citadel. Backed by founders of OpenAI, Meta AI Research, MotherDuck, dbt Labs.
In-office NYC.

MixRank (YC S11) | Software Engineers | 100% Remote (Global) | Full-Time
MixRank processes petabytes of data every month through web crawling. Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.
Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests.
Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.
