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.

- Partner daily with product to build, ship, measure, and iterate
- Build within the laws and regulations governing payments and financial services
Who You Are
- Senior engineer with a strong payments background and real experience building payment systems and integrations (fintech a plus)
- Exceptionally high attention to detail; strong finance background is a plus
- Excited to be close to the build and close to customers
- Likes working on a small team and moving fast; bias toward action

About Wonderschool
Wonderschool is an AI-powered marketplace solving the child care crisis by connecting governments, providers, parents, teachers, and nonprofits on one integrated platform.

We assist with licensing, classroom setup, pricing strategy, website creation, enrollment support, daily operations, and more. Our platform is designed to let educators focus on what they do best: caring for and educating children. For governments, we offer AI-powered tools to help manage and expand early education ecosystems. Our technology helps states and municipalities identify child care deserts, support local providers, increase quality, and ensure families can access programs that meet their needs. By unifying data, services, and funding mechanisms, we help public agencies scale solutions effectively and equitably. We are proud to partner with leaders across sectors—from families and educators to policymakers and nonprofits—to create a future where every child has access to early learning.
