Job description

PeakHealth AI is rebuilding primary care around proactive longevity. We pair advanced diagnostics with AI-driven care plans—think Levels × One

Our founder has previously founded two unicorn telehealth companies, our Chief Medical Officer is a 4X NYT best seller and we have strong tech and AI talent.

What you’ll own

• Build and scale full-stack features across mobile-web and desktop using React, TypeScript, Next.js (frontend) and Node.js, GraphQL, Postgres (backend).
• Translate clinician workflows and complex lab data into intuitive, consumer-grade UX — then bring it to life through performant, secure APIs and data models.
• Contribute across the stack: from UI implementation to backend API design, schema modeling (Prisma), and infra/debugging (AWS, CI/CD).
• Collaborate on shared UI and backend standards, evolve our component library, improve test coverage, and help shape engineering culture.

What we’re looking for

• 3–6 years of product engineering experience with strong ownership across the stack.
• 3+ years of React/Next.js experience; you can build clean, high-performing interfaces from Figma with motion and UX polish.
• Backend fluency: Node.js, GraphQL, Postgres, and comfort with Prisma or similar ORMs.
• Pragmatic about tech debt and infra — you ship, own, and debug your code in production.
• Strong startup instincts: you value velocity, clarity, and thoughtful code reviews over process-heavy ceremonies.

Comp: Competitive salary + equity variable to experience + benefits
