Full Job Description
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 Senior Software Development Engineer to own and drive the architecture, design, and delivery of systems that operate at massive scale. You'll define technical direction for ambiguous problem spaces, lead design across multiple workstreams, and mentor engineers - all while shaping how the next generation of builders, both human and AI, interact with source control at Amazon.

Key job responsibilities

- Own end-to-end design, architecture, and delivery of source control infrastructure serving millions of repositories and billions of monthly code operations across Amazon.

- Lead technical design and drive architectural decisions for highly available services supporting GitFarm, GitHub Enterprise, and GitLab - platforms that cannot go down.

- Define and build APIs and platform capabilities that enable AI agents and automated systems to interact with source control safely and at scale.

- Identify and drive technical investments that improve platform scalability, reliability, and developer experience across the source control ecosystem.

- Drive operational excellence - set the bar for on-call, reduce operational toil through automation, and advance our AI-native operations approach.

- Influence technical direction across ASBX to deliver a unified, secure developer experience across all source control platforms.

- Mentor and grow engineers on the team, raising the technical bar through design reviews, code reviews, and hands-on guidance.

A day in the life

As an SDE III on Code Services, you own technical direction for systems every Amazon developer depends on. You define approaches for ambiguous problems - whether that's architecting how AI agents safely interact with source control at scale, designing GitLab's integration into Amazon's infrastructure, or solving monorepo performance challenges that break assumptions baked into git itself. You influence across multiple workstreams, mentor engineers, and set the technical bar for the team - all while shipping production systems with the highest standards for availability and performance.
