Job description

The Team: 

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.

How you'll make an impact

  • Deliver critical user-facing features that improve loan application and rate check experiences-directly driving improvements in conversion and funding form submission metrics.
  • Maintain full-stack web applications through monitoring of key system metrics such as latency and error rates at scale
  • Help define and build the next-generation, platform funding form that supports multiple products, contributing to architectural direction and long-term scalability.
  • Strengthen engineering excellence by improving system performance, reliability, and on-call health for the features you build and own.

Minimum Qualifications 

  • Bachelor's degree in Computer Science, Engineering, or Mathematics, or a related field (or its equivalent) + 4 years of experience
  • Experience delivering end-to-end features across frontend and backend systems, including APIs and microservices.
  • Strong frontend development experience building customer-facing web applications with a focus on performance, usability, and experimentation.
  • Experience working in cross-functional environments with Product, Design, and other engineering teams.

Preferred Qualifications

  • Experience improving conversion funnels or other high-scale, metrics-driven user journeys through experimentation (e.g., A/B testing, personalization).
  • Experience operating in a microservices-based architecture.
  • Experience in fintech or other highly regulated, high-availability environments.

Position location This role is available in the following locations: Remote

Time zone requirements The team operates on the East/West coast time zones. 

Travel requirements As a digital first company, the majority of your work can be accomplished remotely. The majority of our employees can live and work anywhere in the U.S but are encouraged to to still spend high quality time in-person collaborating via regular onsites. The in-person sessions' cadence varies depending on the team and role; most teams meet once or twice per quarter for 2-4 consecutive days at a time.
