Description
- We are seeking a Applied Scientist to join the Alexa AI PAPI (Personalization, Autonomy, and Proactive Intelligence) Science team. In this role, you will architect and scale next-generation memory intelligence and personalization capabilities that power Alexa Plus—enabling it to learn, memorize, reason, and deliver deeply personalized, useful, and delightful responses that approach the vision of a true general personal assistant. Your responsibilities include: * Advance core technology: Invent, design, and implement state-of-the-art solutions for previously unsolved problems in agentic AI, memory retrieval, and context management at scale. * Solve real customer problems: Build systems that learn from heterogeneous, multi-modal customer signals—conversations, device visual signals, ambient activities, purchase histories, and more—to deliver the right information, in the right format, at the right time. * 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. You will push the boundaries of what personalized AI assistants can do—bridging research in generative AI, memory systems, and agentic reasoning with production systems that operate at Amazon on scale. Your innovations will directly shape how millions of customers experience Alexa Plus daily.
