Senior TypeScript Functional Backend Engineer

Description

We are hiring a Senior Functional Backend Engineer to help us connect to insurance portals across the U.S. to ingest, transform, and deliver structured healthcare data — including claims, EOBs, plan documents, and accumulators.

This role sits at the intersection of production reliability and system design. You'll own integration health in production, onboard new portals, expand data coverage, and write clean, strongly typed backend code. The team values functional principles - composability, explicit error handling, type safety - and uses Effect extensively, but prior Effect experience is not required.

This is hands-on engineering in a system where correctness and clarity matter.
