We're hiring a Trust & Safety Engineer to join Runway's AI Safety and Responsibility team. Runway builds AI world models - general-purpose simulators for robotics, science, and storytelling — and this role exists to keep that safe as it reaches millions of users.
Stack: TypeScript API on ECS/Fargate, Python/PyTorch inference backend, Claude + Gemini for safety/moderation, ClickHouse for abuse signal detection, AWS + GCP, Terraform, Prometheus/Grafana.
It's a generalist role, hands-on across the full engineering lifecycle - from model pre-training through productionisation. We're looking for 3+ years production Python or TypeScript, comfort across the stack, and experience with data pipelines (ClickHouse a plus).
Apply here: https://jobs.ashbyhq.com/runway-ml/c3ebd871-ea78-4b71-80a2-7..., or feel free to reach out with any questions (info in bio).
We're also hiring for a bunch of other roles, across Engineering, Research, GTM, Marketing, Finance, Legal: https://jobs.ashbyhq.com/runway-ml?utm_source=kW6D9goed3
ViyaMD is building a physician-grade clinical intelligence platform for legal, insurance, and healthcare teams. We analyze large, messy medical record sets and turn them into clinically accurate timelines, reasoning, and insights in minutes.
We’re hiring for two senior roles:
# Staff Software Engineer: Own core product and platform systems: medical record ingestion, document understanding pipelines, backend/data infrastructure, clinical workflow, and production reliability.
We’re looking for:
* 5–8+ years of software engineering experience
* Strong Python/Typescript/backend engineering skills
* Experience with distributed systems, data-intensive apps, or large-scale document processing
* Ability to own ambiguous problems from architecture through production
* Interest in healthcare, clinical data, legal-tech, or AI products
# Staff ML Engineer: Own how ViyaMD evaluates and improves its clinical AI: define eval metrics, run model/agent evaluations, improve prompts and workflows, and close the loop through better retrieval, agentic systems, and fine-tuned models.
We’re looking for:
* 5–8+ years of professional experience
* Strong hands-on AI/ML evaluation experience
* Experience with LLMs, RAG, agents, fine-tuning, or applied ML systems
* Fluency in Python
* Healthcare or clinical experience is a strong plus, but not required
We’re especially excited about people who want to set the technical bar, work close to real users and data, and build AI systems that must be accurate and trusted in high-stakes domains.
You'd work directly with our founding team, with real influence over how we build. Comp: competitive salary, meaningful early-stage equity, and benefits. Email me at hari AT viyamd.com, if you're interested.
YC is hiring Product Engineers to build the future of YC -- and increasingly, software for startups everywhere.
We're a team of ~20 engineers building everything from Work at a Startup and Demo Day to investor software, founder tools, AI systems, and new open source projects. We don't have PMs. Engineers talk to users, decide what to build, and ship quickly.
Some of what we've been building:
* New products: GStack rethinks the software stack for an AI-native world. GBrain explores persistent memory and knowledge systems for AI. Paxel and other AI-powered products help founders—and increasingly everyone else -- build software and companies faster.
* Products at scale: We build and operate Work at a Startup (2M+ candidates, 1000s of early startups), Demo Day, our investor marketplace, SAFE signing, founder CRM, and the software that powers YC itself.
* Data: YC has over 20 years of proprietary startup data. We're applying it to how we think about the future of YC's batch, fundraising tools, hiring, recommendations, and entirely new ways to help people start and grow successful companies.
AI has fundamentally changed how we build software, and we're looking for engineers who are already experimenting with coding agents, MCP, LLMs, context engineering, evals, developer tooling, and whatever comes next. Our stack includes Rails, React, Postgres, Python, TypeScript, LLM APIs, and plenty of experimental infrastructure, but we're much more interested in great builders than expertise in any particular framework.
We're in person in San Francisco (Dogpatch). You'll work closely with founders and alongside people like Garry, Jared and Diana, helping define how YC—and startups more broadly—build software in the AI era.
We offer competitive compensation, carry in the YC fund, and a small, high-autonomy engineering team.

Home-based care should be the default in American healthcare. It isn't, mostly because the technology has never been good enough. Patients heal faster at home, it costs a fraction of facility-based care, and it's what people actually want — yet the industry runs on phone calls, spreadsheets, and systems built in the 90s. We started Axle Health because we think that's fixable, and because the stakes are high enough that it's worth doing right.
We're Axle Health, and we think in-home care deserves world-class technology. We're building the operating system for home-based healthcare — the scheduling intelligence, the clinician tools, the logistics coordination — everything that has to work perfectly so a clinician shows up at the right door at the right time with everything they need. It's a hard and important problem, and we're just getting started.
The complexity is real: real-time scheduling optimization across dynamic clinician networks, last-mile logistics that make Uber Dispatch look simple, integrations with every flavor of EMR and payer system you've never heard of, mobile-first tools that have to work in spotty cell coverage in someone's living room, and the compliance surface area that comes with handling PHI at scale — we need to build it all, and we want people who think this stuff is genuinely fun.
