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

The Opportunity

Liong is hiring a Medical Leader 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.

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.
• Help shape Legion’s clinical brand: how we talk about psychiatry, AI, medication management, access, safety, outcomes, and patient trust.
• Own Legion’s medical quality standards across psychiatric evaluation, medication management, documentation, follow-up, escalation, and patient outcomes.
• Develop clinical protocols and care standards that make Legion easy for payers, PCPs, therapists, health systems, and other referral partners to trust.
• Partner with product, engineering, data, clinical operations, and compliance to ensure Legion’s AI-enabled workflows are clinically sound, explainable, and responsibly governed.
• Support referral growth by helping clinical partners understand when Legion is appropriate for their patients and how to refer with confidence.
• Help build payer-facing and partner-facing clinical materials, including care model overviews, outcomes narratives, quality frameworks, and medical policies.
• Recruit, mentor, and support psychiatrists, PMHNPs, supervising physicians, and future clinical leaders.
• Represent Legion in high-stakes clinical conversations, including payer diligence, partner diligence, medical advisory discussions, and regulatory conversations.

Qualifications

• MD or DO with board certification in psychiatry.
• Child/adolescent psychiatry, addiction psychiatry, consultation-liaison psychiatry, medical informatics, or public psychiatry experience is a plus.
• 5+ years of clinical psychiatry experience, ideally including outpatient psychiatry, telepsychiatry, medication management, and clinically complex populations.
• 2+ years in a medical leadership role.
• Strong external presence with the ability to build trust with payers, referring clinicians, health systems, regulators, advisors, and clinical partners.
• Experience supporting payer, provider, health-system, employer, or strategic partnership conversations.
• Strong judgment around psychiatric prescribing, medication renewals, medication safety, risk stratification, escalation workflows, and documentation quality.
• Experience supervising psychiatrists, PMHNPs, collaborating physicians, therapists, or multidisciplinary clinical teams.
• Comfort turning clinical standards into partner-facing materials, payer-facing narratives, medical policies, and operational workflows.
• Strong understanding of telehealth, multi-state clinical operations, CPOM, licensure, supervision models, HIPAA, state medical board expectations, and payer quality requirements.
• Familiarity with measurement-based care, outcomes tracking, PHQ-9/GAD-7 workflows, safety planning, suicidality escalation, and evidence-based psychiatric care.
• Ability to work cross-functionally with product, engineering, data, operations, legal, compliance, growth, partnerships, and founders.
• High judgment around AI in clinical care. You do not need to be an engineer, but you should understand how to explain, govern, and responsibly scale AI-enabled clinical workflows.
• Low ego, high ownership, and strong executive presence. You can speak with a payer in the morning, advise on a referral partnership at lunch, review a clinical protocol in the afternoon, and help founders make a hard judgment call by evening.
