Are you passionate about solving complex business problems at scale through Generative AI? Do you want to build intelligent systems that reason, act, and learn from minimal supervision? Are you excited about taking innovative AI solutions from proof-of-concept to production? If so, we have an exciting opportunity for you on Amazon's Trustworthy Shopping Experience (TSE) team. At TSE, our vision is to guarantee customers a worry-free shopping experience by earning their trust that the products they buy are safe, authentic, and compliant with regulations and policy. We give customers confidence that Amazon stands behind every product and will make it right in the rare chance anything goes wrong. We do this in close partnership with our selling partners and empower them with best-in-class tools and expertise required to offer a high-quality selection of compliant products that customers trust. As a Senior Applied Scientist, you will lead the development of next Gen AI solutions to automate complex manual investigation processes at Amazon scale. You will work on some of the most fascinating challenges in applied AI—building systems that reason and act autonomously, learn rich representations from structured and relational data without extensive labels, adapt rapidly from limited examples, improve through feedback and interaction, seamlessly connect visual and textual understanding, and compress complex model capabilities into efficient, deployable systems. Your innovations will deliver significant impact to cost-of-serving customers while maintaining the highest standards of trust and safety. This role offers end-to-end ownership—from initial research and proof-of-concept through production deployment. You will see your innovations serving hundreds of millions of customers within months, not years.
Job Responsibility:
Design and build next-generation agentic AI systems that think, plan, and act—capable of multi-step reasoning, dynamic tool use, and autonomous task execution that transforms how investigations are conducted
Invent novel solutions across the AI frontier: autonomous reasoning, self-supervised representation learning, few-shot adaptation, feedback-driven optimization, and multimodal intelligence
Develop deep expertise in research areas strategic to the organization while maintaining solid understanding across adjacent domains
Identify and frame ill-defined customer and business problems, devising new research methodologies using a customer-obsessed scientific approach
Tackle ambiguous, high-impact challenges where the problem itself isn't yet fully defined—and shape the science roadmap that solves them
Automate complex investigation workflows involving unstructured text, documents, images, symbols, and rich relational data—directly impacting hundreds of millions of customers
Anticipate and articulate key scientific challenges of current and future customer needs, proactively presenting interventions to address them
Drive ideas from whiteboard sketch to production system—prototype rapidly, iterate relentlessly, and deploy solutions that scale
Engineer efficient, production-ready systems by distilling models into lightweight, cost-effective deployments without sacrificing capability
Build a proven track record of repeatedly delivering innovative, impactful scientific solutions into production
Write clear, compelling narratives and documentation that enable others to understand, reproduce, and build upon your work
Provide architectural guidance for AI systems—whether building from scratch or transforming existing solutions
Write significant portions of critical-path code that form the backbone of complex systems, setting the standard for technical excellence
Maintain deep knowledge of team solutions and proactively drive utilization and improvement upon state-of-the-art techniques
Independently assess emerging technologies and make sound decisions on adoption for your systems
Champion engineering best practices and conduct rigorous peer reviews that raise the bar for the entire team—your solutions, code, and designs set the example for others
Influence team strategy by contributing to roadmaps, goals, priorities, and scientific approach
Lead and participate in science reviews for your team and adjacent teams
Build consensus by communicating effectively, harmonizing discordant views, and resolving contentious technical debates
Actively participate in hiring top scientific talent and mentor fellow scientists—improving their skills and accelerating their ability to deliver impact
Drive the team's scientific agenda and role model the pursuit of publications at peer-reviewed venues when appropriate
