A day in the lifeAs an SDE II on Code Services, you design and build systems that every Amazon developer depends on. You might spend the morning optimizing git operations for monorepo performance, then shift to building APIs that AI agents use to interact with source control. You collaborate with teammates across GitFarm, GitHub, and GitLab to deliver features and resolve operational issues. Your customers are literally all of Amazon — from principal engineers to AI coding assistants. You balance shipping new capabilities with operating infrastructure that is always available.

About the team

The Code Services team owns all source control at Amazon — GitFarm, GitHub, and GitLab.

We manage Amazon's external open-source presence on GitHub and operate one of the largest GitLab installations in the world.
