Affirm is a fintech company that provides a buy-now-pay-later service, letting consumers split purchases into predictable installments without hidden fees. The Trust and Safety Foundations team within Checkout Engineering builds the data pipelines and backend systems that power Affirm's risk assessment, credit reporting and compliance workflows. As a Staff Software Engineer on this team you would help define the technical roadmap for a year-long horizon, turn ambiguous risk-related problems into concrete designs, and drive cross-functional projects from concept through launch. Day-to-day work includes designing highly available services, improving monitoring and alerting, establishing code-review and design standards, and mentoring other engineers through code reviews, tech talks and hands-on guidance.

The role suits engineers with eight or more years of backend experience, proficiency in Python or Kotlin, and a track record of building scalable distributed systems on AWS using technologies such as MySQL, Spark and Kubernetes, who can navigate ambiguity, communicate clearly and lead by example.
