Ever wondered what powers the content experiences seen by hundreds of millions of Prime members across every Amazon marketplace on the planet? Prime Customer Experience Engineering (CXE) provides the governance and technical backbone for the development lifecycle of every Prime experience, spanning the CX layer and the wiring that connects it to the data sources behind it. We own the core framework for building and maintaining Prime CX widgets and the content experimentation systems for every Prime experience. Together, these systems power Prime C - Xs across functions like acquisition, onboarding, engagement, and retention, across channels including .com, email, notification, text, and WhatsApp ensuring Prime-owned C - Xs, which drive roughly 70% of Prime member growth, scale consistently and reliably. Within CXE, the CX Authoring team owns the content infrastructure layer the self-service platforms, tools, and frameworks that enable teams across Prime to create, configure, localize, and deploy customer experiences at global scale without deep engineering expertise. We're building an AI-native framework that is fundamentally reimagining how Amazon creates customer experiences. Our vision is bold: compress CX development from weeks of manual effort down to hours of AI-assisted generation with human-in-the-loop validation - pioneering design-to-code Gen. AI workflows, automated content generation, intelligent compliance checking, and multi-agent orchestration. Our north star? Anyone can create world-class Prime experiences without writing code, AI handles localization and optimization automatically, and launch timelines collapse from weeks to days - across all Prime marketplaces worldwide. At Amazon and in the Prime CX Authoring team, you will grow into the high-impact, innovative person you know you're ready to be. Do you want to build AI-native platforms that fundamentally reimagine how software is developed? Do you enjoy working on generative AI, scalable distributed systems, and self-service tooling in a team environment? At Amazon, we hire the best minds in technology to innovate and build on behalf of our customers. The focus we have on our customers is why we are one of the world's most beloved brands - customer obsession is part of our company DNA. Our Software Development Engineers (SD - Es) use innovative technology to solve complex problems and get to see the impact of their work first-hand. Key job responsibilities 1. Build the Gen.
