• Work with patient and provider data with the care regulated data requires.
• Make technical decisions and deliver with minimal supervision.

• 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.
