The opportunity

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.

What you'll do

  • Define and drive the vision for resilience engineering at Affirm, with a: focus on production load testing and chaos engineering as first-class engineering practices.

  • Lead and mentor a team of engineers building platforms and tooling for safe production experimentation.

  • Partner with infrastructure, product, and security leadership to embed: resilience validation into the software development lifecycle.

  • Establish best practices for safely testing system limits and failure scenarios in production.

  • Own the design and evolution of platforms that enable safe, controlled: production load testing and fault injection.

  • Ensure strong safeguards are in place, including isolation boundaries,: approval workflows, and automated rollback mechanisms to protect real users.

What they're looking for

  • Build systems that provide end-to-end observability, traceability, and: auditability for all resilience experiments.
  • Drive reliability improvements by systematically identifying weaknesses: through load testing and chaos experiments.
  • Establish monitoring, alerting, and incident response practices tailored to proactive resilience validation.
  • Work closely with engineering teams to design and execute production load tests and chaos experiments safely.
