Senior Machine Learning Finance Jobs in Oregon (NOW HIRING)

The Team: 

Marketplace Optimization builds the intelligent systems that power Upstart's AI lending marketplace. Our teams make real-time decisions about how borrowers are matched with capital, how offers are constructed, and how the marketplace evolves through experimentation. We solve complex optimization problems at scale, balancing borrower experience, investor objectives, profitability, and operational efficiency while operating some of the most critical services at Upstart.

Within Marketplace Optimization, engineers join one of two closely related teams:

• Monetization builds the marketplace services that optimize marketplace economics through origination fees, offer construction, and experimentation capabilities that allow the business to rapidly evolve monetization strategies.
• Matching & Offer Selection builds the real-time decision engine that intelligently matches borrowers with capital providers while balancing borrower outcomes, investor commitments, marketplace efficiency, and business objectives.

As a Senior Software Engineer, you'll partner closely with Product, Machine Learning, Pricing, Capital Markets, Lending Partnerships, and Analytics to build highly reliable distributed systems that power millions of lending decisions.  You'll work on systems at the heart of Upstart's lending marketplace. The software your team builds determines how borrowers are matched with capital, how offers are constructed, and how marketplace decisions are executed in real time. It's an opportunity to solve challenging distributed systems problems while building software with direct, measurable impact on borrowers, investors, and the business.
