If you’re energized by tackling meaningful problems, excited to innovate with purpose, and motivated by work that truly matters, we’d love to hear from you. The Team: Upstart’s Solutions and Integrations team builds and scales the technology that connects our lending partners to Upstart.

The team owns core banking and API integrations that automate lender onboarding and downstream loan workflows, with a focus on helping our lenders purchase loans seamlessly, supporting new lending products, and building scalable integration and production support models. We've already built integrations with several major core banking platforms, and our priority now is helping more lending partners go live quickly, reliably, and at high quality. We're a small, collaborative team that works directly with lenders and partners across Product, Engineering, Implementation, and Account Management.

You will work directly with lending partners and internal teams to gather requirements, configure integrations, map data, establish connectivity, test end to end workflows, troubleshoot issues, and support successful production launches.
