Qualifications

• 5+ years of software engineering experience with deep expertise in backend and platform engineering.
• Strong proficiency in TypeScript and/or Python for API and service development.
• Proven track record building scalable, production-grade REST or GraphQL APIs.
• Solid understanding of authentication (OAuth2, OIDC), API security patterns, and authorization model design.

• Security and Compliance by Design: Establish patterns for authentication, authorization, rate limiting, PHI access control, and audit logging. Ensure HIPAA compliance is embedded in platform design from day one.
• AI and LLM Integration Patterns: Define and implement reusable patterns for integrating AI capabilities into product APIs, including LLM routing, streaming responses, tool orchestration, and model output handling.
• Observability and Reliability: Build logging, monitoring, and alerting infrastructure so the platform is operable and debuggable at scale.
• Full-Stack Feature Delivery: Contribute to product feature development end-to-end using TypeScript and Next.js, from server-side APIs to rendered UI.
• Architecture Reviews and Standards: Drive architecture reviews and define backend engineering standards that the full engineering team builds on.
