Full-Stack Product Designer — Growth + Core Product (backed by Y Combinator, $5M+ ARR, $23M+ 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 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 tens of thousands of 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.

ROLE LOGISTICS

• Job Type: Full-Time

• Role Type: Product Design / UX & UI / Brand / Growth Creative

• Ideal Experience Level: 5+ years or equivalent evidence of exceptional shipped work

• Location: Onsite in San Francisco, CA

THE OPPORTUNITY

Legion is hiring a Full-Stack Product Designer to own the experience from the first ad or landing page through onboarding and ongoing care. You will combine deep product design with strong visual, brand, and web craft, helping patients understand what Legion does, get into care, and feel confident about what comes next.

You will work closely with Growth, Product, Engineering, and the founders. Your work will span patient experiences, clinician and operator tools, the website, landing pages, lifecycle touchpoints, and acquisition creative. A shared, prioritized backlog will make the tradeoffs between core product delivery and growth experiments explicit.

This is a hands-on individual contributor role with end-to-end design ownership: understand the problem, explore alternatives, prototype, craft the interface, contribute directly to implementation, and improve the shipped result. Full-stack means breadth across the design process and product/growth surfaces, including regularly shipping well-scoped production PRs in close partnership with Engineering.

AI-native design is a core expectation of this role. You will use tools such as v0, Claude Design, Figma AI, Cursor, and comparable tools throughout the design process—not as occasional add-ons, but as everyday tools for divergent exploration, interactive prototyping, implementation, and rapid iteration.

✅ RESPONSIBILITIES AND DELIVERABLES

• Translate user needs and complex care workflows into clear journeys, information architecture, interaction flows, prototypes, and polished interfaces.

• Design patient onboarding and ongoing care experiences alongside clinician and operator workflows, with particular attention to clarity, trust, accessibility, and mobile usability.

• Define complete interaction states, including loading, empty, error, permission, and recovery experiences; write clear interface copy and remove avoidable dead ends.

• Build a practical design system with reusable components, patterns, and guidance that helps the team ship consistently and quickly.

• Ship production PRs regularly. This is a product-design role—not a software-engineering role—but you are expected to work directly in the codebase and open production-quality PRs for well-scoped changes such as instrumentation, internal tools, workflow logic, UI and copy improvements, prototypes, and small fixes. You should be comfortable testing, reviewing, and safely rolling out your work in close partnership with engineering.

• Bring Legion's brand to life across the website, landing pages, lifecycle communications, and acquisition creative.

• Develop paid-creative concepts and experiment variants with Growth; use performance feedback to sharpen the message and improve the experience.

• Use user research, usability testing, product analytics, and experiment results to identify friction and decide what to improve.

• Connect acquisition promises with the product experience, creating a coherent path from first impression to activation and continued care.

• Work AI-natively throughout the design process. Use v0, Claude Design, Figma AI, Cursor, and comparable tools to generate and compare directions, build high-fidelity interactive prototypes, test ideas earlier, accelerate implementation, and shorten the loop from concept to shipped product—while applying strong judgment to every final decision.

YOU’LL BE SUCCESSFUL IF YOU…

• Ship clear, useful, visually excellent experiences that patients and teammates can use with confidence.

• Improve usability, task completion, onboarding conversion, and adoption of the product surfaces you own.

• Create faster design-to-engineering cycles with fewer avoidable implementation gaps and a reusable component foundation.

• Deliver a steady cadence of thoughtful landing-page and creative experiments with explicit hypotheses and useful learning.

• Earn trust as a partner who prioritizes well, explains tradeoffs clearly, and follows through on the shipped result.

IDEAL BACKGROUND AND SKILLS

• A portfolio of shipped product work that shows the problem, your personal contribution, alternatives, tradeoffs, interaction detail, and outcomes.

• Strong product-design depth and strong visual craft across typography, layout, brand, and web. We need evidence of both.

• Experience taking ambiguous problems from discovery through polished UI and production collaboration with engineers. Comfortable working directly in a codebase, using Git and pull requests, testing well-scoped changes, and incorporating engineering review before a safe rollout.

• Demonstrated fluency with AI-native design and prototyping workflows is required. You should be able to show how you have used v0, Claude Design, Figma AI, Cursor, or comparable tools to materially improve the speed, breadth, fidelity, or quality of shipped work.

• Website or landing-page work and the ability to develop effective acquisition creative; curiosity about what makes creative perform.

• Comfort using qualitative feedback and quantitative evidence without reducing every design decision to a single conversion metric.

• Clear writing, low ego, high ownership, and the ability to balance speed with quality in an early-stage team.

• Experience in healthcare or another trust-sensitive consumer product is helpful. Sound judgment and strong shipped work matter most.

COMPENSATION & BENEFITS

• Salary: $180,000 – $230,000 annual base salary, based on experience

• Early-Stage Equity: Very competitive

• Health Insurance: Medical, dental, and vision benefits

• Additional Perks: In-person retreats, meal stipends, learning stipend, and AI tooling budget

• Time Off: Flexible, unlimited vacation policy

• Work Setup: Full-time, onsite in San Francisco, CA

• Impact: Own the design quality of a coherent care experience across product and growth.

• Autonomy and Learning: Own your work end-to-end with close cross-functional and founder collaboration.

• Growth Opportunities: Broaden your design leadership as Legion scales, while staying close to users and the work.

HOW TO APPLY

Apply through this posting and include a portfolio link. Show at least one substantive product case study and work demonstrating your brand, website, or growth craft. Explain what you personally owned and what changed after launch.

Show us how you work with AI. Include at least one example of moving from problem framing to prototype or shipped experience with AI tools. Explain what the tools accelerated, what you changed or rejected, and how your judgment improved the final result.

We will share the interview process and timing with candidates as the search progresses.
