About the role
Location: San Francisco (Rincon Hill)
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.

- Design for correctness first, because money movement demands it
- Work directly with customers to understand real-world failure modes and edge cases
- 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
- Comfortable with the regulatory landscape around payments, banking, and cards
- Uses AI tools and figures things out independently
Compensation & Benefits

Application
