Founding Medical Leader, Psychiatry (backed by Y Combinator, $5M+ ARR, $20M+ raised)

🧠 About Legion Health

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 <u>first company ever to receive regulatory authorization to let AI prescribe psychiatric medications</u>, 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.

🚀 The Opportunity

Legion is hiring a Founding Medical Leader, Psychiatry to help make Legion one of the most trusted names in AI-native psychiatric care.

You will be the clinical voice of the company: building trust with patients, clinicians, payers, referral partners, regulators, and the broader medical community. You will help shape how Legion explains its model of care, how we earn confidence from the healthcare ecosystem, and how we build partnerships that expand access to fast, affordable, high-quality psychiatry.

This is a founding executive role for a psychiatrist who can operate externally and internally. You should be comfortable speaking with payers, health systems, primary care groups, referral partners, clinicians, and regulators, while also helping define the clinical standards that make those relationships durable.

The right person combines the clinical credibility of a leading psychiatrist, the partnership instincts of a healthcare executive, the trust-building judgment of a medical affairs leader, and the product curiosity required to help build AI-native care responsibly.

✅ Responsibilities and Deliverables

Serve as Legion’s senior clinical voice with payers, referral partners, health systems, regulators, advisors, provider groups, and the broader medical community.

Build trust in Legion’s model of AI-native psychiatry by clearly communicating how care is delivered, how clinicians remain involved, and how patient safety is protected.

Partner with the founders on payer, provider-referral, employer, health-system, and strategic partnership conversations.
