## About the role

We're a small team building a live consumer credit product — a dynamic credit card: application funnel, KYC/credit decisioning, a double-entry ledger, statements, payments, and ACH. You'll own backend systems where correctness with money is the whole job. You'll help shape the product itself as well. You need strong product judgement.

## What they're looking for

- Strong backend fundamentals: data modeling, Postgres, async/queue-driven systems, idempotency, and designing for failure
- Comfort owning a feature across the stack: DB → API → infra → tests → deploy → monitoring
- The ability to operate with incomplete requirements and drive a problem to a concrete outcome
