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. What You'll Do · You will be responsible for owning and delivering quarterly goals for your team, leading engineers on your team through ambiguity to solve open-ended problems, and ensuring that everyone is supported throughout delivery. · You will support your peers and stakeholders in the product development lifecycle by collaborating with product management, design & analytics by participating in ideation, articulating technical constraints, and partnering on decisions that properly consider risks and trade-offs. · You will proactively identify project, process, technology or business issues, advocate for them, and lead in solving them. · You will support the operations and availability of your team’s artifacts by creating and monitoring metrics, escalating when needed, and supporting “keep the lights on” & on-call efforts. · You will foster a culture of quality and ownership on your team by setting or improving code review and design standards for your team, and advocating for them beyond your team through your writing and tech talks. · You will help develop talent on your team by providing feedback and guidance, and leading by example. What We Look For · You have 4+ years of experience designing, developing and launching backend systems at scale using languages like Python or Kotlin. · You have a track record of developing highly available distributed systems using technologies like AWS, MySQL and Kubernetes. · You have experience building or evolving CI/CD, deployment, or release automation systems that reduce manual toil and improve rollout predictability, recovery, and auditability across many engineering teams. · You are comfortable working on shared developer infrastructure and defining clear platform interfaces, templates, or guardrails that make it easier for product teams to adopt standard deployment patterns with confidence. · You have experience defining a technical plan for the delivery of a significant feature or system component with an elegant, simple and extensible design. You write high quality code that is easily understood and used by others. · You are proficient at making significant changes in a large code base, and have developed a suite of tools and practices that enable you and your team to do so safely. · 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. · This position requires either equivalent practical experience or a Bachelor’s degree in a related field.
