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.

We are seeking a Senior Software Engineer to join our Infrastructure Platform Engineering team, ensuring the reliability, availability, and operational efficiency of Affirm’s distributed systems. This role is ideal for engineers who thrive in highly scalable, cloud-native environments, focusing on incident response, observability, automation, and system resilience.

As part of the Platform, Reliability and Infrastructure Operations group, you will work on proactive failure mitigation, operational tooling, service scaling strategies, and on-call effectiveness to ensure low-latency, highly available services across Affirm's compute, storage, CI/CD, and observability stacks.

Platform Reliability Engineering at Affirm is a crucial team that helps our Engineering partners to "Operate What They Own" with excellence to protect customer experience. Our team accomplishes this by defining frameworks and best practices for operating applications, building tooling, and providing training and consulting services.
