About Alpaca

Alpaca Health is the operating system for autism care. We make it possible for clinicians to start and run their own practices — handling the operational complexity that usually stops them. Billing, payroll, payouts, intake, clinical workflows, parent communication. We handle it all so they can focus on delivering care.

Nearly 50 clinicians have launched their businesses on Alpaca. Over 200 children receive care through our platform every day. We're at $1.8M ARR, growing 30% month-over-month. Small team, everyone owns real problems end-to-end. No filler roles.

The Role

Alpaca runs a lot of complex operations — payroll, billing, insurance claims, intake, eligibility — and today, too much of it depends on people catching things by hand. The numbers are right, but only because smart people check them every cycle.

Your job is to make that unnecessary. You'll build the automation, tooling, and product workflows that turn manual checklists into durable systems. Monday might be a backend pipeline that validates payroll before anyone looks at it. Wednesday might be a parent-facing UI that shows a family exactly what they'll owe before a surprise bill shows up months later. Friday might be an LLM-powered workflow that cuts hours of clinical documentation down to minutes.

You work across the stack. You lean systems, but you build product when it matters — and at Alpaca, it matters a lot.

You'll be one of the first five engineering hires and report directly to the CTO.

What You'll Own

• Reconciliation and audit tooling. Build the systems that validate payroll, payouts, and billing before any human reviews them. "Is this number right?" becomes a dashboard, not a Slack message to the CTO.
• Workflow automation. Convert manual ops processes — intake, eligibility checks, end-of-period processing — into guardrailed automation that handles the happy path and flags the exceptions.
• Patient responsibility. Build the calculation and disclosure system that gives parents clear, accurate expectations about costs — before they get a surprise bill months later.
• AI-powered workflows. Build LLM-driven features that reduce operational and clinical burden — documentation assistance, intake automation, intelligent routing. Own making these features reliable and safe in a healthcare context.
• End-to-end testing on critical paths. The reconciliation tooling you build is itself a form of continuous testing. Own the confidence that core workflows produce correct results across edge cases.
