Autonomous medical care
At Legion Health, we believe everyone deserves fast, affordable, and world-class health care, and we’re developing the AI infrastructure to deliver it ourselves at world scale.
Legion is building autonomous medical care (the AI doctor), starting with psychiatry. Our AI-native care-delivery platform currently automates 95% of the administrative work required for us to deliver direct patient care. We also recently became the first company ever to receive regulatory authorization to let AI prescribe psychiatric medications, allowing us to not only collapse health care’s admin costs but also its clinical labor costs—shifting this industry’s economics from humans to tokens.
Our technical moat is hard to copy—we combine rich data, production AI, doctors in the loop, and end-to-end care operations to deliver measurably better care to a clinically complex patient population. This has helped us produce 25K+ total visits in just 2 years, all while holding ops costs flat and achieving industry-leading patient NPS and retention. While the last generation of healthcare startups made the existing system incrementally more efficient, Legion is rebuilding full-stack care delivery from first principles. Our vision? A 10X better patient experience that’s higher quality, less expensive, and more scalable than ever before. And a 10X better clinician experience that frees our providers to focus on what matters most: caring for patients.
Legion Health is backed by Y Combinator, leading venture capital firms, and founders from Function Health, Modern Health, Everly Health, Trusted Health, Clipboard Health, PatientPing, Sesame Care, Faire, EasyPost, and fuboTV.
Join us as we build the future of health care: faster, higher-quality, and more affordable, powered by doctors and AI working together.

Legion is hiring someone unusually sharp early-career technical operator who will work directly with leadership to solve high-leverage problems across growth, revenue, finance, hiring, culture, legal, investor work, operations, and internal AI systems (Office of the Founders).
This is not an executive assistant role. It is not a traditional business operations role. And it is not a junior Chief of Staff role with a better title. It is a new kind of role for the AI-native era: a technical, high-agency generalist embedded with senior leaders to make the company dramatically faster.
You will sit close to leadership, see the company’s most important problems early, and be expected to build solutions fast. One day you might prototype an internal AI tool that saves the operations team 30 hours per week. The next day you might analyze patient reactivation, build a GTM model, improve a hiring process, automate investor reporting, draft a strategy memo, or create a workflow that helps a non-technical team specify exactly what they need before engineering gets involved.
The center of gravity is GTM and company leverage. You should constantly be asking: where are we losing patients, revenue, speed, quality, or focus, and what can I build, automate, analyze, or fix this week to move the company forward?
The best candidates are likely 0-3 years out of school, with a computer science, engineering, data science, operations research, financial engineering, applied math, statistics, economics, or similarly rigorous background. You may have early experience in consulting, banking, finance, startups, product, data, or engineering. What matters most is raw intelligence, speed, taste, grit, communication, AI fluency, and demonstrated ability to make things.
This is a career-accelerating role for someone who wants unusual exposure very early. You will be in the room for meaningful company decisions, work directly with senior leaders, get tough deadlines, and learn by doing real work that matters.

We also recently became the first company ever to receive regulatory authorization to let AI prescribe psychiatric medications, allowing us to not only collapse health care’s admin costs but also its clinical labor costs—entirely shifting this industry’s economics from humans to tokens.
Our technical moat is hard to copy—we combine rich data, production AI, psychiatrists in the loop, and end-to-end care operations to deliver measurably better care to a clinically complex patient population. This has helped us produce 20K+ total visits and $4.2M in ARR in just 2 years (~4× YoY), all while holding ops costs flat and achieving industry-leading patient NPS and retention.
While the last generation of healthcare startups made the existing system slightly more efficient—for example, by moving providers from out-of-network to accepting insurance—Legion is fundamentally rebuilding full-stack care delivery from first principles. With a global TAM of $2.15T and our recent regulatory approval for autonomous prescribing, we plan to 10× in the next year with a national rollout.
