Backend Engineer

Responsibilities

• Implement backend features in our Python stack: API endpoints, data models and migrations, and the glue between services.
• Write meaningful tests and make it (or its equivalent) pass — correctness is proven by the controls, not by hoping.
• Contribute to integrations with wearables and clinical data sources under guidance.
• Instrument what you build — add the metrics and logs that make your code observable — and learn our tooling (CloudWatch, Sentry) and how the platform runs in production.
• Learn and respect the safety/privacy context — PHI handling, least privilege — as part of normal development.
• Use AI coding agents effectively, and build the habit of verifying what they generate.
• Communicate clearly in code, PRs, and updates.

Qualifications

• Solid programming fundamentals and some backend experience (Python a plus; we care more about strong fundamentals and learning speed).
• Comfort with APIs, databases/SQL, and version control; eagerness to learn good testing and design.
• A real drive to build and ship, and curiosity to keep learning.
• Openness to AI-augmented development with a healthy, verify-it mindset.
• Exposure to FastAPI / SQLAlchemy / Postgres, AWS, or healthcare data (FHIR, wearables) preferred.
• Any experience in regulated, safety-critical, or high-reliability software preferred.
