Legion Health (YC S21) | Founding Engineer (AI-Native Ops Infra)
Location: San Francisco | ONSITE | VISA SPONSORSHIP Compensation: $130k–$190k + Equity
Legion Health is building the AI-native operations layer for mental health care. They run their own psychiatric practice and use AI agents to handle the complex "backend" of healthcare—scheduling, intake, documentation, billing, and risk detection. They have $3M+ ARR, $7M+ raised, and their infrastructure currently supports 2,000+ patients with only one human support lead.
They are hiring a Founding Engineer to own their backend and agent systems end-to-end. This is not a "wrapper" role; you will be architecting the state machines and event streams that turn clinical intent into reliable operations.
