Job description

The mission of Fitness and Fandom is to create delightful discovery, browse, and search experiences that connect customers to strategic shopping programs and enable best-in-class experiences for Sports fans worldwide.

We are looking for a Senior Software Development Engineer to drive the technical vision and delivery of our Licensed Sports fan experience — building the systems that power end-to-end fan shopping across NFL, NCAA, MLB, NBA, NHL, International Soccer, F1, and emerging leagues. You will help make Amazon the premier licensed sports shopping destination by designing and building scalable, AI-powered systems that deliver personalized, event-driven experiences to millions of fans.

You will partner closely with product, applied science, design, and business teams to translate ambitious product strategies into robust, production-grade solutions. You will set the technical bar for the team, mentor engineers, and drive operational excellence across services that handle high-traffic sporting events and real-time customer experiences.
