Software Development Engineer, Checkout Applications Team

We're looking for an engineer to join our team building lightning-fast, frictionless checkout experiences for Amazon's retail website. This is a great time to join: we are modernizing the Checkout platform and adding support for agentic purchasing flows that will change how hundreds of millions of customers complete their orders.

As a Software Development Engineer on the Checkout team within the Purchase Experience organization, you will design and deliver full-stack features across the entire software lifecycle using Java, JavaScript, TypeScript, and React. You will work on distributed systems at massive scale and plug generative AI into checkout infrastructure. If you like solving hard problems and shipping software that customers use every day, we'd love to hear from you.

Key job responsibilities

• Design and build full-stack features for the Checkout platform using Java, TypeScript, and React (Native and Web), covering the full software lifecycle from design through deployment and operations.
• Own and improve distributed microservices that run frictionless, high-scale checkout experiences, keeping performance and maintainability in balance.
• Plug generative AI frameworks into checkout workflows to support agentic purchasing flows for customers.
• Work with product managers, UX designers, and engineers across 300+ teams to turn business and customer needs into reliable, well-documented solutions.
• Coach fellow engineers through code reviews and technical guidance, helping maintain a high-quality codebase and spotting ways to improve team operations.

A day in the life You will start your day reviewing metrics and operational health for the services you own, then jump into building features that millions of customers will use at checkout. You might spend the morning pairing with a teammate on a system design for a new agentic purchase flow, then write and test code in the afternoon. You will work closely with product managers, UX designers and researchers, and business intelligence engineers to create the best purchase experiences for our customers.

About the team The Checkout team's mission is to offer the most trusted and easy purchase experience on Earth. Collectively our team builds experiences that empower customers to collect and manage the items they intend to buy; provide the critical order details that enable them to make informed purchase decisions; surface contextual product and program-related benefits/recommendations to help them basket build and deepen their relationship with Amazon.

Our team of builders owns the software, systems, and processes that enable 300+ teams at Amazon to innovate on behalf of our customers each year in the final stages of a customer’s purchase journey. We are investing in modernizing our platform and launching agentic purchasing capabilities.

We care deeply about building an inclusive environment where everyone can be successful.
