Software Development Engineer II, Amazon Software Builder Experience (ASBX)
About The Position
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.
