• Fluency with Git and collaborative development workflows.
• Experience deploying and operating services in AWS or Azure.
• Proficiency with CI/CD and Dev Ops practices.
• Bachelor’s degree in CS or related field, or equivalent hands‑on experience.

• Active, daily use of AI coding tools integrated into development workflow.
• Ability to critically evaluate AI‑generated code for correctness, security, and maintainability.
• Experience providing AI tools with meaningful context to get higher quality output.
• Comfortable working in a workplace where AI‑supported delivery is standard.

• Deep experience with FHIR resources, profiles, and implementation guides.
• Familiarity with SMART on FHIR, OAuth2, and healthcare authentication/authorization models.
