Founding Full-Stack Engineer

We're building a revenue cycle orchestrator on top of Attune's Agentic Voice platform: claims files come in, get enriched through RAG and EHR/payor integrations, and turn into supervised actions—payor calls, member outreach, appeal packets. This role owns the backbone that ties it together: the workflow engine that sequences those actions and the state that drives the human-in-the-loop portal.

You'll be one of three founding engineers. Expect to make foundational architecture decisions, write production code across the stack, and shape how the whole product hangs together.

Design and build the workflow orchestration layer: how a claim moves through states, when actions fire, how human approvals gate progress, and how it all stays auditable.

Build the services behind the approve / deny / kick-off experience—the queues, the state machine, and the APIs the portal runs on.

Integrate with Attune's voice and agentic APIs to launch and track payor and member calls as first-class workflow actions.

Make reliability and observability a feature, not an afterthought—retries, idempotency, and clear audit trails in a domain where correctness is money.

Partner closely with the product lead and the other founding engineers; move fast without leaving a mess.

6+ years building production full-stack software; comfortable owning a service end to end from schema to UI-facing API.

Strong backend fundamentals: workflow/state-machine design, event-driven systems, queues, and data modeling for complex domains.

Experience with long-running, multi-step processes and human-in-the-loop or approval workflows.

Pragmatic full-stack range: primarily backend, but able to build and reason about the front end the portal needs.
