Affirm is reinventing credit to make it more honest and friendly, giving consumers the flexibility to buy now and pay later without any hidden fees or compounding interest. Affirm, Inc. proudly includes Affirm, PayBright, and Returnly.
Affirm’s Machine Learning Underwriting team solves problems critical to Affirm’s business model - assessing creditworthiness in real time. Our innovative products necessitate the creation of novel machine learning solutions to drive both existing and new products/markets.
The Core Machine Learning Underwriting (CAML) team builds Affirm essential real-time point-of-sale underwriting models. These models determine who is approved for an Affirm loan, for how much, at what interest rate, and for what loan durations. These models are central to Affirm’s continued success and growth, and need to be explainable to the user and scalable across regions.
