Builder Works at Amazon sits at the intersection of traffic engineering, region flexibility, and developer enablement. Every time a customer clicks on Amazon.com, complex underlying systems route requests to the right machines in the right regions, computing and delivering content in milliseconds, even during Prime Day or Black Friday peaks.

We build frameworks and systems powering store presentations, catalog pages, and content pipelines used by both developers and creative teams to author Amazon’s shopping experiences at scale. Our mission: enable seamless, engaging customer experiences while operating at massive, global scale. Design and implement scalable systems that route customer requests to the optimal region, balancing latency, cost, and availability. Build and optimize frameworks enabling the creation of dynamic store presentations and catalog pages, supporting high traffic events like Prime Day.

Develop and maintain traffic engineering proxies and networking solutions to support region flexibility and data center expansion. Collaborate with internal Amazon developers and creative teams to build tools that enhance content authoring and presentation, reducing time-to-publish for promotional and cross-promotional content. Engineer systems to precompute and fetch data from thousands of sources, balancing real-time computation with precomputation for consistent low-latency delivery. Design with scalability in mind, ensuring system stability and performance at tens of thousands of transactions per second.

Contribute to the exploration and integration of AI-powered developer experiences within Builder Works to enhance productivity for Amazon’s engineering teams.
