About this role

🧠 ABOUT LEGION HEALTH

At Legion Health https://legionhealth.com/, 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 https://nypost.com/2026/03/27/business/artificial-intelligence-can-now-prescribe-mental-health-drugs/, 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 an AI Lifecycle Product and Marketing Leader to build the AI-native patient communication engine that helps people start care, stay in care, come back when they lapse, and feel personally supported across months and years of treatment.

This is not a typical lifecycle marketing job. We are not looking for someone to manage a static email calendar, build a few drip campaigns, and optimize subject lines. Legion has rich patient data, production AI, clinical workflows, scheduling events, insurance data, intake behavior, appointment history, medication renewal patterns, and care operations all inside one vertically integrated system. That means we can build something far more powerful: a personalized, proactive communication engine that knows where each patient is in their journey and automatically helps move them to the next right step.

You will build the system that makes Legion feel impossibly responsive. A patient who stalls in intake should get the right nudge. A patient who books but does not complete prep should get the right reminder. A patient at risk of missing follow-up should be guided before they lapse. A patient due for renewal should understand what to do next. A patient who churned should receive a thoughtful, relevant path back. Over time, the engine should become more intelligent, more personalized, and more autonomous.

The right person combines the lifecycle rigor of DoorDash, Instacart, Airbnb, or Sephora; the patient-journey discipline of Hims, Thirty Madison, Headway, or Talkiatry; the retention instincts of Noom, Peloton, WHOOP, or Duolingo; and the AI-native curiosity required to build communication systems that can generate, personalize, test, and improve patient journeys at scale.

This is a founding systems-builder role. You should be comfortable designing lifecycle strategy, mapping patient states, writing copy, building CRM logic, creating segments, using AI tools, QAing flows, debugging event data, launching experiments, and partnering with product, engineering, data, ops, and clinical teams to create an engine that increasingly works on its own.

✅ RESPONSIBILITIES AND DELIVERABLES

- Build Legion’s AI-native lifecycle engine across activation, booking, visit completion, follow-up adherence, medication renewal support, retention, reactivation, and winback.

- Design the patient communication system across email, SMS, push, in-app, transactional reminders, AI-assisted outreach, and future owned channels.

- Map the full patient journey into clear lifecycle states, triggers, audiences, suppressions, escalation rules, personalization rules, and next-best-action logic.

- Use Legion’s patient data to create highly personalized journeys based on intake status, appointment behavior, insurance status, treatment stage, follow-up cadence, renewal needs, engagement, risk of lapse, and communication preferences.

- Partner with product, engineering, and data to instrument the events, properties, data models, and workflows needed for intelligent lifecycle automation.

- Build AI-assisted communication workflows that can draft, personalize, route, test, and optimize messages while staying within approved clinical, compliance, and brand guardrails.

- Create proactive flows for abandoned intake, incomplete booking, pre-visit preparation, appointment reminders, no-show prevention, post-visit follow-up, refill and renewal nudges, reactivation, churn recovery, and long-term engagement.

- Build segmentation and personalization systems that can support thousands of patient-specific journeys instead of one-size-fits-all campaigns.

- Partner with clinical operations to ensure every me
