Requirements

  • 5+ years building production financial systems: billing, payments, ledgers or revenue infrastructure, at a fintech or a usage-based SaaS company.
  • Deep fluency in money-correctness patterns: idempotency, double-entry accounting, exactly-once event processing, reconciliation and safe migrations of financial data.
  • Hands-on experience with Stripe (or similar processors) and a billing/invoicing platform, including contract, subscription and usage-based models.
  • Strong TypeScript and SQL. Comfortable with Postgres and analytical stores (ClickHouse or similar) at high event volume.
  • Working knowledge of accounting: AR/AP, revenue recognition, deferred revenue, month-end close. You can talk with Finance in their language.
  • You work well across teams. You'll partner daily with Provider, Trust & Safety, Sales, CS and Finance, and turn messy business asks into clean systems.
  • High agency and AI-forward. You use coding agents daily and like automating away manual finance ops.
