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

  • 10+ years of software engineering experience , with significant experience owning and shipping customer-facing products in production
  • Strong product judgment. You can take an ambiguous customer problem, understand what actually matters, and translate it into a product and technical solution
  • Strong technical depth across application architecture, APIs, data modeling, backend systems, and the tradeoffs required to build reliable products
  • Excellent technical judgment and an instinct for finding the simplest solution that solves the customer's problem without creating unnecessary complexity
  • High ownership. You don't stop at shipping code—you care whether customers use what you built, whether it solved the problem, and what should happen next
  • Ability to create clarity from ambiguity and independently identify the highest-leverage product and technical problems to solve

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.

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...
