Software Engineer, Conversion

The Conversion Engineering team sits at the intersection of product performance and business growth at Upstart. We are responsible for optimizing how borrowers move through the application journey—from rate check to funding—directly impacting Conversion Rate, one of the company’s most important operating metrics and a key driver of revenue.

As a Software Engineer on the Conversion Engineering team, you will play a critical role in building and evolving the core borrower experiences that drive ~80% of company revenue. You’ll work on highly visible, user-facing systems such as the funding form and got rate page, helping to shape both the technical direction and execution of key initiatives.

Our team builds and iterates on high-impact experiences while partnering closely with Product, Design, and Machine Learning to launch new product flows, ship model upgrades, and continuously test and personalize borrower journeys. This is a high-impact team with ambitious goals and significant headcount growth planned.
