Software Engineer, Core Product (Contract)

You'll pair closely with our senior billing engineer, who carries deep domain knowledge about payer-specific edge cases, billing rules, and payout conditions. Today he executes that knowledge manually every cycle. Your job is to encode it into automated workflows so he can shift from doing the manual work to owning the correctness of the automated version.

Our platform engineer will be building the foundational domain models and invariants. You build the product and automation layers on top of that foundation — the systems and interfaces that turn platform correctness into operational leverage.

3+ years of experience in fintech, payments, billing, or a similar domain where money has to be exactly right.

You're obsessed with correctness and idempotency. You think about what happens when a job runs twice, a webhook fires out of order, or a record updates mid-calculation. You don't hand-wave edge cases.

You build across the stack. You're comfortable writing a backend reconciliation pipeline and a product interface in the same sprint. You lean systems, but you can build the UI when it matters.

You build tooling, not just features. You've built reconciliation systems, audit logs, internal dashboards, or workflow engines. You find satisfaction in making manual processes disappear permanently.

You're comfortable with ambiguity. The business rules you're automating are still being discovered. You can work with incomplete specs, ask the right questions, and ship something that handles edge cases gracefully rather than waiting for a perfect spec that never arrives.

You ship quickly and iterate. We're a small, fast team. You own your work end-to-end — from understanding the manual process, to building the automation, to proving it's correct.

Alpaca's vision is an autonomous clinic — a system that handles the full operational complexity of running an autism care practice so that humans can focus on clinical care and family relationships. Every manual process you automate moves us closer. Every reconciliation check you build reduces the risk that a family gets a wrong bill or a therapist gets paid incorrectly. Every AI workflow you ship gives clinicians hours back.

You'd be joining early enough to shape how the product works, with enough traction that you're not guessing whether anyone wants it. The product is live, the growth is real, and the problems are worth solving.
