Amazon Leo is building a global e-commerce experience for Internet Service Provider (ISP) customers, and we need a Front End Engineer II to help us do it. You will work with React and Next.js to design, build, and ship features that serve customers worldwide.

We are part of the Leo Commerce engineering organization at Amazon, building the e-commerce experience for a global ISP customer base. Our team works closely with backend commerce services, product, marketing, and business partners to launch new experiences from scratch. We are scaling the team and investing in AI-based development and operational workflows to meet the growing needs of our customers. If you are looking for a place where you can grow your expertise by tackling new problems regularly alongside an inclusive group of engineers, we would be glad to have you.

A day in the life

You might start your morning reviewing a pull request from a teammate, suggesting improvements to a React component's accessibility and performance. After standup, you pick up a new feature that doesn't have a clear precedent yet, sketching out an approach with your product manager before writing code. In the afternoon, you pair with a designer to refine interaction details for an upcoming launch, then dig into an operational metric that looks off, tracing it to a rendering edge case you fix before it reaches customers.
