* Build for scalability: Design and deploy customer-feedback-driven, self-optimizing agentic architectures that serve millions of customers across Amazon surfaces, programs, and marketplaces.
* Drive platform-level impact: Contribute to a platform science team responsible for organizing and reasoning over diverse customer interactions to continuously improve personalization quality.
* Champion scientific rigor and responsible evaluation: Own the end-to-end science lifecycle—from hypothesis formulation and offline experimentation to online A/B testing and production accountability. Design evaluation that measure personalization quality and safety at scale, ensuring every launch is backed by statistically sound evidence.
This is not incremental work.

Your innovations will directly shape how millions of customers experience Alexa Plus daily.
