## About the role

You'll be one of the first engineers on Santé's payroll build, and a technical owner of the financial systems where correctness is non-negotiable: ledgers, accounting sync, and the money movement rails underneath them. This means designing systems an auditor could read — double-entry ledgers, idempotent payment execution, reconciliation that proves everything ties out — and debugging from ambiguous production signals ("this merchant's books are off by $0.47 since the 9th") down to root cause.

## What they're looking for

- Build Santé's payroll product from the ground up — earnings computed from shift data the platform already has, tax withholding, payment execution, and filings integrations
- Develop Santé’s bill pay product that moves our customers from paying their suppliers by check to one-click handling accounts payable directly in our platform
- Embed bank accounts directly into our OS so that our customers have access to their card processing revenues in minutes
- Own and harden our accounting integrations (QuickBooks today), where a sync bug shows up as a merchant's books not balancing at month-end
- Design and maintain the ledgers behind loyalty, gift cards, and deposits — correct, idempotent, and auditable under concurrent writes
- Establish the financial-correctness patterns (double-entry ledgers, idempotency keys, reconciliation jobs, timezone cutoffs) that other teams adopt
