• 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.

• 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.
