Senior Front End Engineer, Shopping Foundations
AmazonUI (AUI) is looking for a Senior Front End Engineer 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. 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. We value testability, maintainability, code quality, and cogent design.

Key job responsibilities
Lead design and development of scalable, reusable UI components for Amazon’s global shopping experience

Architect performant, accessible, and modular front-end systems used across worldwide platforms

Drive adoption of modern front-end technologies, standards, and best practices

Integrate GenAI into development workflows to accelerate component creation and documentation

Establish QA frameworks, performance monitoring, and accessibility standards for reliable releases

Partner with design, product, and platform teams to deliver cohesive customer experiences

Mentor engineers and promote a culture of technical excellence and innovation

A day in the life
- You’ll collaborate with designers and engineers to build next-generation UI components that power millions of customer experiences.
- A typical day may involve designing a new pattern for AUI, integrating GenAI-assisted tools to generate component code or documentation, optimizing load performance for high-traffic pages, and reviewing code for accessibility and design consistency.
- You’ll work closely with partner orgs to align UI frameworks, share learnings, and evolve Amazon’s front-end systems at scale.
