About the job
The Code Services team in Amazon Software Builder Experience (ASBX) owns all source control at Amazon — GitFarm, GitHub, and GitLab. Amazon builds on our platforms — literally. Millions of repositories, hundreds of thousands of production systems, and every AI agent writing code at Amazon today push changes to infrastructure we own and operate. We're looking for a Software Development Engineer to build and scale the platforms where all Amazon code lives, at a time when AI agents are becoming first-class participants in source control alongside human developers. You'll design and deliver systems that operate at massive scale while shipping features that shape how the next generation of builders — both human and AI — interact with code.
Responsibilities
- Design, build, and operate source control infrastructure serving millions of repositories and billions of monthly code operations across Amazon.
- Deliver scalable, highly available services that support GitFarm, GitHub Enterprise, and GitLab — platforms that have >4 nines of availability.
- Build APIs and platform capabilities that enable AI agents and automated systems to interact with source control safely and at scale.
- Drive operational excellence — own on-call, reduce operational toil through automation, and contribute to our AI-native operations approach.
- Collaborate with engineers across ASBX to deliver a unified, secure developer experience across all source control platforms.
- Solve hard distributed systems problems — monorepo scaling, high-throughput git operations, cross-platform consistency, and performance at Amazon scale.
- Contribute to technical design, code reviews, and mentoring of junior engineers.
