Senior AI Platform & API Engineer

Humana Inc; Dallas (TX); On-site; USD 107,000 - 147,000; Full time

Job summary

Humana Inc. is hiring a Senior Full Stack Engineer to build a scalable platform and API layer supporting AI capabilities across CenterWell clinics. You will design core backend services, REST/GraphQL APIs, and secure, compliant data flows for PHI.

You will contribute to the UI with Next.js/React, ensure robust security patterns, and drive architectural standards across the team. This role is based near designated IT locations including Dallas, TX.

Qualifications

• B.S. or M.S. in Computer Science, Engineering, or a related field (or equivalent experience)
• 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
• Working knowledge of HIPAA requirements, particularly secure transmission, storage, and access control for PHI
• Experience with Next.js and React sufficient for full-stack feature contribution
• Demonstrated ownership of complex backend systems end-to-end, from architecture through production operation
• Hands-on experience with AI-assisted development tools and LLM coding harnesses (Claude Code, Pi Agent, Cursor, Codex, or similar)

Responsibilities

• Platform and API Architecture: Design and lead development of core backend services, REST and GraphQL APIs, and service-to-service integrations that connect all layers of Centerwell's AI product stack.
• 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—not bolted on after the fact.
• 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.
