Several of our engineering teams are hiring and our interview process is designed to make sure we find the best mutual team fit. To get an idea of the different teams and what they’re working on, read below: 

Consumer Team: Our consumer products enable customers to find new merchants, take out Affirm loans to buy from those merchants, and service their full loan lifecycle across both web and mobile platforms.

Risk Team: Our platform provides a comprehensive automated decision-making system for all of Affirm's financial products, from identity verification to fraud detection to underwriting, credit, and pricing. We are focused on managing our risk exposure, growing our business, and empowering our developers, data scientists, and product managers with data that enables them to understand our customers’ behavior and empower their own decision-making.
