About The Position

The Unsecured Installments team is responsible for one of Upstart's core lending products, which helps borrowers access credit through a seamless, digitally native experience. The team owns critical parts of the borrower journey, including offer generation, pricing, underwriting, funding, and the overall borrower experience.
