• Impact and Career Growth: You will invent new experiences and influence customer-facing shopping experiences; this is your opportunity to work within the fastest growing businesses across all of Amazon!
• Turn customer needs into data science problems and actionable recommendations for your product, engineering, and sales partners
• This role combines analytical rigor, technical strength, product focus, and business understanding
• Build and apply LLM-based solutions (retrieval-augmented generation, prompting, and agentic workflows) to solve Ad Sales problems and generate seller-facing insights and recommendations
• Translate ambiguous business problems into data science problems, and build the statistical and machine learning models that complement LLM workflows, such as ranking, retrieval evaluation, segmentation, and forecasting
• Analyze large, complex datasets, including conversation and LLM interaction data, to surface insights, quantify gaps, and identify opportunities to improve our generative AI products
• Design and run experiments (A/B tests, offline and online evaluations, causal inference) and define metrics that measure the quality, accuracy, and business impact of LLM-driven solutions
• Write code (Python, SQL) to acquire, transform, and analyze data at scale, and partner with applied scientists and engineers to move solutions into production
• Present findings and recommendations clearly to technical and non-technical audiences, and mentor junior data scientists on your team
