Software Engineer, Unsecured Installments

Unsecured Installments is one of Upstart's core lending products, helping borrowers access credit through a seamless, digitally native experience. The team owns critical parts of the borrower journey across offer generation, pricing, underwriting, funding, and borrower experience, while working closely with the broader lending platform that powers Upstart at scale. Recent work has focused on improving borrower flows, repricing and rate flexibility, partnership experiences, and the overall quality of the customer-facing experience.

As a Senior Software Engineer on the Unsecured Installments team, you'll be a technical leader for the frontend and full-stack experiences that borrowers interact with directly. Working primarily in React and TypeScript, you'll own the delivery of large, multi-month projects, shape the architecture of the team's mobile-web and full-stack surfaces, and set a high bar for quality across the borrower experience. You'll partner closely with product, design, and backend engineers to turn ambiguous problems into durable, well-architected solutions, and you'll mentor other engineers along the way.

How you’ll make an impact

• Own the design and delivery of large, complex frontend and full-stack initiatives using React and TypeScript, from planning and sequencing through launch and long-term maintenance.

• Set technical direction for the team's frontend architecture and full-stack patterns, owning a 3–6 month roadmap and proactively addressing systemic gaps that threaten team effectiveness.

• Partner closely with product, design, and backend engineers to translate roadmap priorities and borrower needs into scalable, high-quality experiences.

• Raise the bar for engineering excellence through strong component and API design, thoughtful state management, testing, observability, and operational rigor across borrower-facing surfaces.
