Description

AmazonUI (AUI) is looking for a Senior Software Development Engineer (SDE-III) to modernize Amazon's front-end developer experience. AUI provides a library of front-end components, build tools, a templating engine, and runtime libraries used by thousands of engineers.

AUI engineers have a range of skills but, as a team, we set the bar for engineering accessible features, deploying client-side code, generating HTML, and ultra-low JavaScript golf scores. Our customer base gives us incredible leverage and the spotlight is often on us. We think in terms of frameworks not features. We make tools and languages.

As a team, we have been using either Kotlin or TypeScript for the last year, though we maintain existing code bases that use Java, Perl, and JavaScript. We use git for our VCS, and a proprietary system for managing our continuous deployments. We value testability, maintainability, code quality, and cogent design. Our products include the front end framework for Amazon, a JavaScript and CSS build system used by thousands, and a compiler for deploying markup templates across multiple languages.
