Pay: $220,000–$300,000 + equity

A fast-growing, venture-backed software and payments company is building payroll, bill pay and banking features from scratch. This engineer will set the patterns every money-moving system at the company follows.

What you'll do

• Build payroll and bill pay from the ground up
• Build ledgers, embedded accounts and accounting syncs
• Set the standards for idempotency, retries and reconciliation
• Find root causes when numbers don't match, and fix them for good

What you bring

• 5+ years building production backend systems, ideally TypeScript or Node
• Transaction guarantees: idempotency, retries, atomicity
• Deep PostgreSQL
• Precision about reconciliation and rounding

Nice to have: payroll, banking or audited ledger systems; ACH, payment processors or accounting integrations; directing AI coding agents
