The mission We’re building a best-in-class multi-modal AI agent product (voice + SMS + email) with the potential to disrupt deeply entrenched software businesses and unify a fragmented industry. We’re a tiny team with real traction pre-product, moving fast, and we care obsessively about craft.
Why this role This is a founding engineering seat: you’ll be an early builder shaping the product, architecture, and quality bar from day one. In the first 3–6 months, the role is highly IC-focused. As we scale (including our first in-person hub/site and new hires), this role has optionality (i.e., growing into a leadership role or staying on the IC track and owning the engineering roadmap) for the right person.
What you’ll do
Build real-time systems for voice (streaming audio, low latency, turn-taking), SMS, and email automation with robust state + memory. Design the foundation: architecture, data model, reliability, observability, deployment, and developer velocity. Set the quality bar: clean code, pragmatic abstractions, testing strategy, “don’t break prod,” and thoughtful product UX. Partner closely with the co-founders on product decisions. You’ll have real influence over what we build and how it feels + how it's designed.
What we’re looking for You should be able to work anywhere in the stack (frontend, backend, infra, integrations) and you know how to make smart tradeoffs.
Strong product sense: you’re obsessive about confusing UI and you want to make workflows feel magical. Systems thinking: you can design for latency, reliability, and iteration speed (especially for real-time voice + agent state). High ownership: you run toward ambiguity, unblock yourself, and care deeply about outcomes. Startup mindset: high-risk/high-reward energy, low ego, high pace.
Bonus points:
Experience with agentic systems: LLM orchestration, tool calling, RAG, evals, prompt/versioning, guardrails. Voice/telephony or streaming experience (WebSockets/WebRTC, audio pipelines, turn detection). Messaging + deliverability experience (SMS workflows, email sending, compliance/opt-in, bounce handling). Familiarity with modern stacks (examples): TypeScript/Node, Python, React/Next.js, Postgres, Redis, queues, Docker, AWS/GCP, observability.
Revieve builds AI-powered personalization for 120+ beauty brands across 40+ countries — think skin analysis, AR try-on, and recommendation engines used by some of the world's largest retailers. We're profitable, ~30 people, a dozen engineers, millions of end users.
We've reorganized around the idea that one builder with the right tools can do what teams used to. This role exists because we believe that's true.
What a week looks like: Mon — a real customer problem lands in front of you, full context, you decide what to build Tue — prototype in Claude Code, something running by EOD Wed — staging up, Loom to founders, iterate on notes Thu — in production, watching real data come in Fri — ship the next iteration or find the next problem
~1–2 hours of meetings per week. No standups. No sprints. No PM in the loop.
We're looking for: → Public proof of building — repos, side projects, real users. We click around it. → AI in production — not demos. Opinions on agents, evals, latency, what fails. → Agentic coding fluency — Claude Code, Codex, MCP, custom harnesses → TypeScript / React generalist — comfortable at any layer → Design taste — you know what's wrong with a screen without a designer telling you → Clear written thinking — READMEs, PRs, post-mortems
IMPORTANT: include a link to something you've built in your application.
Process: recruiter call → paid build session (real problem, you set the pace) → short presentation → done.
Perks: 5 weeks vacation from day one, remote-friendly, options plan, equipment budget, parental leave, competitive salary.

What we’re looking for
2+ years of software development experience. Experience building responsive SPAs with React (or similar frameworks). Solid understanding of JavaScript, React, and Node.js fundamentals. Experience with REST APIs (building or consuming). Curiosity, product sense, and a bias toward shipping
Nice to have
Exposure to GraphQL, Next.js, Nx, or modern frontend tooling

We run a worker wellbeing and compliance platform used by global buyers and their supply chain sites across Asia. We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years.
*The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head.
*What we're looking for:*
- Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it
*What this isn't:* This isn't a greenfield startup with infinite runway. It's a real product with real users, real technical debt, and a migration in progress. If that sounds like a problem, this role isn't for you. If that sounds like the most interesting kind of work, let's talk.
*Details:* - Fully remote, India-based - Senior Software Engineer title

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.

Tables power every financial model, clinical trial, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.
The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.
ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.
ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.
Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.
Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.
Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled. Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate.
Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.
Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.
This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.
We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.
Reach out directly with your gh, linkedin, and resume and why you want this position to lucie@markerlearning.com. Please specify your location, if you are interested in full time, contract or open to both. Make the subject "Founding Engineer Application (I am not a bot)".

COVU is an AI-first insurtech startup rebuilding the 20-year-old legacy infrastructure of the $365B+ insurance distribution industry.
We recently announced our $16M funding round (bringing our total to ~$50M) and launched COVU OS. We aren't just slapping an "AI wrapper" onto old software; we built a task-native orchestration layer from scratch. COVU OS converts messy, unstructured insurance workflows (emails, PDFs, manual triage) into defined tasks, dynamically routing them to the right execution layer—whether that's an AI agent, a licensed human professional, or an offshore team.
We are a scrappy, execution-focused team of builders. We heavily encourage using AI tools (Cursor, Copilot, Gemini) in your daily workflow to ship code faster. If you hate spending months in "discovery" and prefer to just build and own production systems end-to-end, you will fit right in.
The Stack:
Data: Snowflake, dbt, Airflow, Python
Product: TypeScript, React, Node.js / Python backends, Cloud Infrastructure
Open Roles:
Staff Full Stack Engineer (Technical Lead): You will be a foundational technical leader shaping the architecture of COVU OS. Expect deep, architecture-level design work paired with heavy, hands-on IC contributions.
Sr. Full Stack Engineer: You will own complex product surfaces end-to-end, building out the agentic orchestration layer, user interfaces, and enterprise API integrations.
Data Engineer(Remote): You'll be the primary builder of our "Golden Policy Journal," transforming highly complex, messy carrier data into our single source of truth using Snowflake, dbt, and Airflow.
Sr. Product Manager (COVU OS): You will own the roadmap for our core operating system. We need a highly technical PM who can dive into the weeds of agentic workflows and write specs that engineers actually want to read.

Responsibilities: Design, train, fine-tune, and evaluate ML models (LLMs, classification, sequence models) for property insurance. Build and maintain robust data pipelines that feed training, evaluation, and inference workloads at scale. Develop rigorous evaluation frameworks — establish metrics, build rater alignment processes, and apply statistical methods to determine when a candidate model is genuinely better than production. Run controlled experiments, ablations, and A/B tests; communicate findings clearly with appropriate uncertainty quantification. Deploy models to production and own their performance, drift monitoring, and iteration cycles. Collaborate with the engineering team to integrate ML services into our backend (Django/Python) and frontend (React/TypeScript) products. Stay current with the ML literature and translate relevant advances into practical improvements for our products.
Required:
PhD in Statistics, Machine Learning, Computer Science, Applied Mathematics, or a closely related quantitative field (or equivalent research experience with a strong publication or production track record). Strong foundation in statistics — experimental design, hypothesis testing, Bayesian methods, and uncertainty quantification. Minimum 5 years of combined research and applied ML experience, with a proven track record of shipping models to production. Deep proficiency in Python and the modern ML stack (PyTorch, Hugging Face, scikit-learn, pandas, NumPy). Hands-on experience with LLMs, including fine-tuning (LoRA/QLoRA, full fine-tunes), prompt engineering, and evaluation. Strong data engineering skills — comfort building reliable pipelines over messy real-world data, working with SQL and columnar formats. Excellent debugging, problem-solving, and written communication skills.
Why Join Ping: Work directly on ML systems that touch real production traffic from day one. Collaborate with a small, senior team of insurance and tech veterans building products that are reshaping the property insurance industry. Enjoy the autonomy of a research role with the impact of an applied one — your models will be in production, used by real customers, and you will see the results immediately.

We build the market-leading SaaS platform for the home care industry: scheduling, billing, payroll, CRM, and clinical documentation for agencies across all 50 US states and 6 countries. ~10,000 baby boomers turn 65 every day; the agencies using our software help them stay in their homes.
We're are small, fast teams that have gone deep on AI-augmented development. Not as a talking point; as the actual way we work. We prototype aggressively, put working software in front of stakeholders before a traditional process would finish a PRD, and iterate from there. We're looking for engineers who already work this way: driving agents on real codebases, maintaining quality when the machine is doing the typing, and knowing when to throw the output away.
Stack: PHP (backend), React + TypeScript (frontend), MySQL, RESTful APIs, AWS. You'll work across the full stack.
Senior (5+ yrs): Product-minded, systems-thinking engineers. You'd lead 1–2 engineers while still taking substantial features from concept to production solo. You mentor others in code design, systems thinking, and driving AI agents effectively.
Mid-Level (2+ yrs): This is a senior-track role. You'll ship real features with mentorship from senior and staff engineers who are deeply invested in your growth. We want engineers who see where things are heading and want to get ahead of it; going deep on architecture, design, and understanding the problems, not just writing the code.
Both roles: We want concrete evidence you use AI as a real tool, not a novelty. Push the tools until they fail, then tell us about it. We care about quality software that's easy to change, clear writing, and engineers who get curious about the customers, not just the tickets.
Compensation: Salary TBD based on experience. Medical/dental/vision covered in full for the employee. Company-provided equipment.
Apply with a brief resume and a cover letter (written or video — video goes to the front of the line). The cover letter matters; we read it first. Tell us what you've built, how AI has changed the way you work with specific examples, and why this team at this moment.
Candidates only, no recruiters. Feel free to reach out directly via email to wademeredith [at] axis care [dot] com if you have questions. Apply through the website.

Form is an AI fluency/integration startup for executives & their teams. We build AI applications tailored to how clients work, and need an engineer to do the building.
A typical engagement starts with a client describing a workflow eating their week. You scope alongside them, then build something that makes it disappear. Stack is whatever fits: TypeScript and Python, React or Next.js, Claude and other LLM APIs, integrations with the SaaS our clients use (Notion, Slack, Google Workspace). RAG, agents, prompt engineering, and evals when the work calls for them, not for show.
We're looking for someone who has shipped end-to-end as an early engineer somewhere small, has real opinions about LLM applications, and writes readable code. Comfort scoping with clients and communicating in writing is essential, since most of our work happens that way.
1099 fractional, paid monthly. 10-20 hrs/week, $75-150/hour. 40-hour monthly minimum, scaling with client demand. Potential to convert to a full-time role ($150k-$220k) as the practice grows.
Remote, Austin/US-based. To apply: https://formai.build/jobs or email jobs@formai.build.

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.

I'm Ryan, an EM and engineer here at YC. We have a small, 18-person software team with no PMs -- engineers own everything end-to-end.
We build the software behind YC's $6B in investments: tools that help partners evaluate thousands of startups per batch, AI-powered apps that founders use every day, and platforms like Work at a Startup that connect candidates with YC companies. Engineers get unlimited AI tokens -- both for development and to build AI-powered products. What wouldn't you build to help founders + YC with that much firepower?
What makes this different from other roles:
* You'd learn more about startups here than you could possibly imagine. Every batch brings hundreds of founders building things across every industry, and you're right in the middle of it.
* We attend Demo Day, founder dinners, and work directly with partners and many of the companies. (They make great products!)
* We pay well, offer carry in the fund (like equity), and provide generous relocation support if you're not in SF yet.
Two roles open:
* Product Engineer -- full-stack, own the product lifecycle. Rails/React stack. Build tools that power how YC invests in and supports startups. It's a wide range, and sometimes it feels like labs-like work, other times it feels like a supersuit to power founders and our Partners like Garry and Jared.
* Community Builder and Software Engineer -- hybrid role. Run YC's talent-facing programs (meetups, tech talks, career expos) AND build the software that makes them scale. You need to be a great engineer and LOVE to build and support communities.
Checkout more about the roles, and email me directly if you're excited to learn more about startups than you will anywhere else - ryan@ycombinator.com

Healthcare AI company. We monitor IBD patients between doctor visits and catch clinical deterioration before it becomes an ER visit. Real patients, real outcomes, peer-reviewed studies.
Node/Express, React/React Native, Python, MongoDB Atlas, Postgres, AWS (EC2, Ansible, the real stuff, not just Lambda bingo). HIPAA/SOC2. Team of 5. Lots of data. More AI and ML in prod every other week. You will contribute to 5 and 6 figure mistakes and also the 6 and 7 figure outcomes. It's just another day in the life. You will discover your gaps quickly and then you get to close them. You will have real access and real responsibility. Your decisions will have meaningful impact on other people's lives. Some people struggle with that. You can't. You will own things. You will learn things. We will build things.
I am six interviews deep into candidates reading me AWS product pages after being asked about their approach to enrichment. If you have ever debugged something in production and have an opinion about literally anything, please talk to me. If you're interested: resume to eng.hiring@sonarmd.com.
If you're really interested: send a cover letter in .md format (no AI, I will know) with answers to: - Last 3 things you personally shipped to prod, preferably ones that failed or had unexpected results - Most recent thing you learned but are too embarrassed to admit you didn't already know - Your 3 biggest pain points working with AI/LLMs/agents - Most recent thing you built that you're legitimately proud of - Preferred tech stack - How many full, 8-hour-day, 5-day-a-week production shipping years you got under your belt, for real
The .md skips the line. I'll read it before anything else in the inbox.
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.
Email steven@kanary.com with something you've built and why it was hard.

The world doesn't need another ERP. CoPlane is building the Agentic Orchestration platform that enables enterprises to orchestrate intelligent processes across their existing systems. Founded by ex-Stripe/Segment product and tech leads, we're changing how businesses operate their backoffice - helping them scale intelligence not headcount.
We're looking for an exceptional product engineer to grow our small team of engineers that include ex-founders, open source contributors (authors of neovim and neverthrow), and architects of petabyte-scale data platforms.
We are looking for someone that wants to own product features end to end (Python + Typescript/React) but is particularly spiky on frontend and UI. You'll build a platform for billion-dollar enterprises solving their hardest, most mission-critical automation problems.
If you're excited about working at the nexus of data, automation and AI, and want to make a significant impact in an early, well-capitalized startup with large enterprise design partners, we'd love to hear from you.
Roles: Product Engineer.

Aqora is the "Hugging Face for quantum computing". We host datasets, benchmarks, and use-case challenges, plus the orchestration layer to run quantum algorithms and workflows across hardware backends, so results are reproducible, comparable, and actually move the field forward. We grew out of the QuantX hackathons at École Polytechnique and now run competitions and a public datasets hub for partners across pharma, finance, energy, and defense.
We're hiring:
* Senior Full Stack Software Engineer (Rust/React). Build the platform end to end: datasets hub, challenges, leaderboards, and the workflow engine that orchestrates quantum jobs across backends. You own features from schema to UI and care about developer experience. Bonus: data, ML, or research-platform experience.
* Quantum Computing Expert. Design challenges, curate datasets, define benchmarks, and shape how algorithms and workflows run on the platform. Work directly with enterprise partners to translate their problems into something the community can solve. PhD or equivalent depth in quantum algorithms, QML, or optimization.
* Chief Commercial Officer, US. Own US go-to-market end to end: strategy, enterprise pipeline, team build-out. You've scaled commercial functions at a deep-tech, dev-tools, or research-platform company. Based in the US.
* Head of Marketing. Positioning, demand gen, and brand for a category still being defined. B2B technical marketing background required; quantum experience welcome but not necessary, curiosity is.
* Product Manager. Drive the roadmap across the datasets hub, challenges platform, benchmarks, and workflow orchestration. Strong technical instincts and experience shipping developer or research-facing products.
* Sales, EU. Enterprise sales into R&D and innovation teams across Europe. Long, technical sales cycles, consultative selling, comfort talking to PhDs and procurement on the same day. EU-based, remote.

Project Debug raises, sorts by sex, and releases millions of (non-biting) male mosquitoes in Singapore to reduce the local mosquito population and prevent the spread of dengue and other mosquito-borne illnesses. Our trial in Fresno, CA showed a 95% reduction in female mosquitoes during the seasonal peak.
Our engineering team is pretty small and we need a solid generalist engineer who is interested in becoming a domain expert in our factory, where we do automated rearing and sex sorting. If you run a homelab, have tinkered with Arduino, and can prompt/write some Python, we can teach you everything you need to know about our stack (Go, Python, React, Kubernetes, Tensorflow).

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.
