You will work with React and Next.js to design, build, and ship features that serve customers worldwide. Many of these experiences are built from zero-to-one, so you will regularly move from ambiguous problem to working product. You will own the full software development lifecycle, collaborating with product, marketing, business, and backend engineering partners to deliver accessible, performant interfaces. If you enjoy working with AI-driven development workflows, picking up new frameworks quickly, and turning complex requirements into clean user experiences, this is the role for you.Export Control Requirement:Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

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.About the teamWe are part of the Leo Commerce engineering organization at Amazon, building the e-commerce experience for a global ISP customer base.
