Remote Senior AI Full-Stack Platform Engineer

Relha LLC; New York, Northern (NY, KY); Hybrid; USD 128,000 - 176,000; Full time

Job summary

Humana’s CenterWell is seeking a Senior AI Full Stack Engineer (backend focus) to design the core backend platform, APIs, and secure data flows for AI-powered care tools. You’ll shape service patterns, ensure HIPAA-compliant design, and deliver scalable features with TypeScript and Next.js.

You will lead API integration, security-by-design, and observability at scale while collaborating with cross-functional teams to advance AI-driven care platforms.

Qualifications

• BS or MS 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.
