About Prosper Health

Prosper Health is on a mission to make life happier and healthier for autistic and neurodivergent adults, a group that has been systematically overlooked despite a 5x rise in autism diagnoses over 25 years. Prosper delivers specialized mental health services for autistic adults, covered by insurance, and has helped tens of thousands of people.

Prosper has raised a $16.2M Series A and has a Series B underway as it expands into ADHD diagnosis, medication management and clinician supervision tooling.

The Role

Prosper is hiring a Senior Product Engineer (5+ years): a product-minded, full-stack builder excited to own real work in building the first comprehensive platform for autistic and neurodivergent adults. This is a foundational hire as Prosper scales into new verticals, with about 70% greenfield work.

• Design and ship backend APIs and frontend experiences in a TypeScript monorepo (Node/Fastify, React, Supabase, tRPC, Prisma).
• Work directly with operations, clinical teams and incoming PMs to validate and ship solutions to real user problems.
• Own projects end to end with real influence on product direction.
• Contribute to developer experience: CI/CD, observability and code quality.

What You Bring

• 5+ years of full-stack product engineering
• Strong TypeScript with Node.js and React
• Product mindset and end-to-end ownership
• Ability to work in the Chelsea, NYC office 2-4 days a week
