Senior Software Engineer, Backend Continuous Delivery

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.

Our team sits within Developer Productivity, whose mission is to make software development at Affirm simpler and faster across the company. The broader org owns much of the path between a developer’s laptop and production, including developer environments, test automation, code standards, CI/CD, and release engineering, all in service of helping engineers ship code quickly, safely, and with confidence. The Continuous Delivery team’s charter is centered on enabling engineering teams to release independently through strong automation, standard patterns, predictable rollouts, resilient recovery mechanisms, and less manual toil.

This role is uniquely positioned to help solve one of Affirm’s most important engineering challenges: scaling developer productivity in an era where the software development lifecycle is increasingly AI-enhanced. The team builds and improves the platforms, workflows, and guardrails that help engineers move from idea to production faster, with better safety, consistency, and developer experience. We value engineers who listen closely, invite feedback, and work well across organizational boundaries, while also holding a high bar for ownership, technical judgment, and follow-through. Strong candidates will care about building reliable shared systems, reducing friction for other engineers, and making durable improvements that raise the quality and speed of software delivery across Affirm.
