All-in-one POS for liquor stores. Backed by Y Combinator.
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
More about this role
Santé is the #1 operating system for local retailers.
Our platform runs the entire store — point of sale, integrated payments, eCommerce, inventory management, delivery-app integrations, marketing, bookkeeping, and AI Agents — so the owners of liquor, grocery, and convenience stores can compete like the big chains without losing what makes them local.
We're building a future where the corner liquor store has better technology than the national retailer: one place for selling to customers everywhere with AI agents that spots slow-moving inventory and creates the promotion to move it. Every feature we ship lands in real stores the same week, and the feedback loop is direct — our customers call us by name.
We move fast and ship daily. AI-assisted engineering isn't a talking point here; agents like Devin, Claude, and Codex are part of how the team works every day, and engineers who master that leverage ship multiples of what they could alone.
Money Movement owns everything at Santé that touches money after the sale: Payroll , Banking , and Lending .
Today that means the accounting backbone our merchants reconcile their businesses on — QuickBooks sync for invoices, bills, COGS journal...
