Job description

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.

The team collaborates closely with European engineering counterparts and engineers across our global Servicing Engineering organization to build cohesive, scalable solutions, and you'll play an active part in that. If you are passionate about creating world-class user experiences and excited by the challenge of launching products in new regions, join us. Help build the next generation of Affirm's platform and learn what it takes to define our presence around the world.
