Senior Software Engineer

About this role

## About Alpaca Health

Alpaca Health enables clinicians to become entrepreneurs, starting in autism care.

We help clinicians launch and scale their own clinics by providing AI-powered software, payer contracting, and full back-office infrastructure. Our goal is simple: shift power in healthcare away from large consolidated entities and back to clinicians.

We've raised over $14M in funding from early-stage investors like Core Innovation Capital, Adverb Ventures, and South Park Commons, and are building for long-term category leadership. More importantly, we're serving hundreds of patients, while growing 30% MoM.

This role is full-time. We’re looking for candidates based in NYC or open to relocating who are open to 5 days a week in the office.

One day you're designing a schema migration strategy. The next you're building an LLM pipeline for clinical documentation. The day after that you're debugging a billing edge case that only appears when Colorado Medicaid is the secondary payer.

This isn't a job for someone who wants to specialize. It's a job for someone who gets uncomfortable when critical business logic lives in someone's head instead of in code.

## What You’ll Own

• **The core domain model.** Patients, providers, credentials, authorizations, sessions, claims, payments. You design how Alpaca represents these things — and how they evolve without breaking what's already in production.
• **Money invariants.** The rules governing how money moves — rate calculations, payout conditions, payroll logic — live in code, not Notion docs. You make them testable and enforceable.
• **Lifecycle ...
