Senior Backend / Infrastructure Engineer - Healthcare Tech (Hybrid NYC)
We're a mission-driven healthcare technology company backed by leading healthcare-focused VCs, partnering with health plans and state governments to help Medicaid and Medicare members stay connected to their care and benefits.
The Role
We're looking for a Senior Backend/Infrastructure Engineer (5-8+ years) to own backend architecture across our member engagement platform, web onboarding flows, and the integration layer connecting health plan partners and internal systems. Our stack: JavaScript/TypeScript on AWS, Next.js, Supabase, Snowflake, and Postgres. You'll also help deploy pragmatic AI agents across the member experience.
As one of our first in-house senior engineers, you'll shape architecture, engineering practices, and hiring standards as we grow - with real autonomy and scope.
What You'll Do
- Own core backend services (AWS Lambda/ECS/Fargate/API Gateway, Supabase, Postgres, Snowflake)
- Harden workflows currently on low-code tools into production-grade services with proper observability and testing
- Drive architecture for personalization, AI enablement, and a unified member hub
- Lead vendor integrations and migrations; write ADRs and runbooks
- Partner cross-functionally with product, design, ops, and compliance
- Set the bar for API design, testing, observability, and on-call practices
About You
- 5-8+ years owning production backend systems end-to-end
- Strong API design fundamentals (REST/event-driven), regardless of framework
- Proficient in JS/TS, Python, or Kotlin; AWS infrastructure; Postgres/Supabase; Snowflake or similar
- Experience integrating with underdocumented vendor APIs and handling production edge cases
- Observability-first mindset; solid data modeling instincts
- Nice to have: NestJS, Terraform, Auth0, HIPAA/SOC 2 experience, LLM-powered workflow deployment
