AmazonUI (AUI) is looking for an Front-end Engineer (FEE II) to help define a new front-end developer experience for building Amazon.com. 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, JavaScript and Ruby. 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.
In our team you will have the opportunity to:
- Build fascinating new web services and products
- Work directly with our customers and shape the vision of the web stack
- Create and drive metrics to measure complexity
- Brainstorm, prototype, test, and iterate on new ideas
- Work with the latest technologies and tools
- Learn from others and help grow other team members
- See the positive impact of your work on real customers
- Brainstorm, design, and implement front end components and user experience for AUI Customers
Interested in a team with a strong culture and camaraderie? Have the passion to build the best customers experience and the drive to actually ship it? Then we would love to talk to you.
