About Quanta

Quanta is the AI accounting platform for modern finance teams—combining in-house accountants with a general ledger built to scale with your business. Backed by Accel.

About the role

Questions that once took weeks to answer become as routine as a Google search: Why did margins change? Which customers are actually profitable? How are we tracking against budget? We're not bolting AI onto legacy software. Quanta was built from the ground up around granular financial data, flexible primitives, and systems that agents can safely understand and act on.

What they're looking for

  • Full-stack engineering experience , ideally on small, high-impact B2B teams
  • Strong technical fundamentals across modern backend and frontend systems
  • Systems thinking , including API design, data modeling, and reliability
  • Product mindset with good judgment around tradeoffs
  • Comfort with ambiguity , ownership, and self-direction
  • Bonus points for experience with financial systems, ledgers, or accounting workflows. You are excited about working in person with a collaborative team in San Francisco
More about this role

We're building a new system of record for finance, one that understands not just the numbers, but the business context behind them.

We've spent years closing the books for real, fast-growing companies and turning what we learn into product. We've already replaced much of what QuickBooks and NetSuite can do and the manual work surrounding them. Customers are now turning off legacy accounting systems and moving to Quanta.

We're still early. The problems are hard, the ambition is enormous, and there's no playbook for what we're building.

We're a small tight-knit team working together in person in downtown San Francisco....
