- Work with patient and provider data with the care regulated data requires.
- Make technical decisions and deliver with minimal supervision.
What we're looking for
- 5+ years of full-stack development.
- LLM features shipped to production: prompt design, retrieval (RAG), evaluation and handling model failures.
- NestJS and Next.js in production with TypeScript; monorepo experience.
- REST and/or GraphQL APIs, solid PostgreSQL, data pipelines and integrations.
- Observability, Docker and CI/CD.
- C1 English.
- Available to start within two weeks for about six months.
Nice to have: GCP or AWS, Python, HIPAA or regulated data, healthcare or EHR, experience with US companies.
