Software Engineer
Back-end engineer focused on building and operating the core infrastructure for card issuance and transaction processing, including authorization, lifecycle management, tokenization, and security across multiple card products.
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 Affirm Card is one of the company’s fastest-growing products and an increasingly significant contributor to overall platform GMV. Our team builds and operates the systems behind every card issued at Affirm and every transaction processed across Affirm ’s card products, including the Affirm Card and one-time virtual cards. We own the core issuing and processing infrastructure powering authorization, transaction processing, account and card lifecycle management, tokenization, and platform security.
As Affirm continues to expand its card offerings, the scale, complexity, and reliability requirements of our systems continue to grow. You will work on systems that sit directly on the critical path of every card transaction, collaborating closely with product and cross-functional partner teams. This is a unique opportunity to help shape some of Affirm ’s most strategic and fastest-growing products while solving complex engineering challenges at scale.
