Join the Programming Foundations Team within Amazon Builder Experience as a Software Development Engineer. Our team owns the languages, libraries, and tools that Amazon builders use daily to write their software. We work on Java, Python, Rust, TypeScript, and C++ language support, along with libraries like Coral (Amazon's service framework) and LPT (Local Package Testing, a tool for running tests locally). We also build and maintain developer tools including VSCode and IntelliJ plugins, CRUX (Code Review User Experience, Amazon's code review system), Gitfarm (Amazon's git hosting service), and DevSpaces (cloud-based development environments).
In this role, you will build tools that help thousands of engineers across Amazon write, test, and review their code. You will work on test infrastructure and frameworks that teams depend on for their daily work. You will also help integrate AI tools into the development workflow through services like builder_mcp (a Model Context Protocol server that connects AI assistants to Amazon's internal tools) and Ironhide (an AI code assistant).
Your work will directly affect how builders at Amazon do their jobs. When you improve a plugin or fix a bug in a test framework, you help engineers ship their code faster. This is practical work that requires understanding what builders actually need and building tools that solve their problems without getting in the way.
Key job responsibilities
You will design and build developer tools that Amazon engineers use every day. You will work with the languages and libraries that power Amazon's services, making them easier to use and more reliable. You will help maintain our IDE plugins for VSCode and IntelliJ, improving how engineers write and debug code. You will work on CRUX to make code reviews more useful and less tedious. You will build and improve test frameworks so teams can catch bugs before they reach production. You will collaborate with engineers across Amazon to understand their pain points and build tools that address them. You will write code, review code from teammates, and help others debug issues with our tools.
About the team
The Programming Foundations Team is part of Amazon Builder Experience. We work on the basic tools and infrastructure that builders use to write software. Our team includes engineers who care about developer experience and want to make building software at Amazon easier. We do not own customer-facing products directly, but our work affects every team that builds software at Amazon. We focus on doing useful work rather than flashy projects. If you like building tools that help other engineers and want to work on problems that span the whole company, this team might be a good fit.
