Build the core issuing and transaction-processing systems behind every Affirm Card swipe
Affirm's Consumer Engineering team owns the issuing and processing infrastructure that sits on the critical path of every Affirm Card transaction — authorization, transaction processing, account/card lifecycle, tokenization, and platform security. This interview probes whether a 1.5+ year backend engineer can design, ship, and operate systems at that scale with Python or Kotlin, AWS, MySQL, and Kubernetes.
