ABOUT THE JOB

We are looking for a Senior Full Stack Engineer with 5+ years of experience building production-grade applications across the stack. You will work on our Vynca Clinical solution, collaborating closely with design, product, and engineering teammates to deliver performant, secure, and user-friendly software that improves the delivery of high-touch care.

You’ll own features end-to-end—from backend APIs to frontend UI—and work across a modern stack that includes React, TypeScript, FastAPI, and GraphQL. We are looking for someone excited by clean code, thoughtful design, and a strong sense of ownership in building product-focused software.

This is a hybrid position based in San Mateo, CA, with an expectation of working from the office 2 days per week.
