Job description

At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most. 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, CI/CD pipelines, test automation, dependency management, 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.

• You will strike the right balance of speed and quality in your work, ensuring that we hit our business goals while protecting our systems from downtime.
• You will contribute to a sense of community on your team by engaging in growth and development activities.

What We Look For

• You have previous work or internship experience designing, developing and launching backend systems at scale and are experienced using one of Python or Kotlin.
• You are familiar with the building blocks of distributed systems, and the technologies like AWS, MySQL and Kubernetes.
• You have mastered taking a simple problem or business scenario into a solution that interacts with multiple software components, and executing on it by writing clear, easily understood, well tested and extensible code.
• You are comfortable navigating a large code base, debugging others' code, and providing feedback to other engineers through code reviews.
• Your experience demonstrates that you take ownership of your growth, proactively seeking feedback from your team, your manager, and your stakeholders.
• You have strong verbal and written communication skills that support effective collaboration with our global engineering team.
