About the role
Senior Software Engineer, Payments
Location: San Francisco (Rincon Hill)
Company Overview
Mission: Make high-quality early childhood education accessible to all by empowering childcare providers with tools and support while helping parents find quality learning environments.
What We're Building: A category-defining platform at the intersection of marketplace, SaaS, and public sector systems, increasingly powered by AI. Series B backed by a16z, Goldman Sachs, and First Round.
The Role
Own the engineering behind a payments platform that processes at least $3 billion through our platform, working alongside a small, dedicated team. We move money across banking, debit cards, Stripe, SAP, partner advances, and payroll, we run our own billing platform, and we lean on third-party partners for most of our fintech capabilities, so much of this is integration, orchestration, and tracking work. There is a lot to build here. You will consolidate and refactor a system built across many legacy integrations into something clean, reliable, and fast, and you will spend a lot of time directly with customers.
