Amazon's Customer Experience and Business Trends (CXBT) organization is hiring a Senior Data Scientist for its Benchmarking, Economics, Analytics and Measurement (BEAM) team. BEAM's mission is to improve customer experience across every Amazon business by turning fragmented internal and external data into decision-grade intelligence for senior leaders. This role anchors our Topline View of Retail initiative: an always-on competitive intelligence capability that fuses third-party transaction panels with Amazon's internal signals to answer how Amazon is winning or losing share of wallet, across segments, categories, and time. You will not just analyze metrics — you will decide which metrics should exist, then build the statistical and machine learning models that generate, forecast, and explain them. Given a new business question and a pile of raw panel and internal data, you are the person who defines what "competitiveness" means, translates it into a defensible, reproducible metric and model, and defends the methodology to skeptical senior stakeholders. We are looking for someone with exceptional business judgment and metric intuition, paired with deep hands-on modeling skills: a strong point of view on what to measure, and the technical ability to build the models that measure it at scale. You should be equally comfortable pressure-testing a model's assumptions and explaining its "so what" to a VP in two sentences. Key job responsibilities - Own the definition, methodology, and evolution of BEAM's competitiveness metrics (e.g., share-of-wallet, segment-level penetration, price/selection/fulfillment competitiveness), including the trade-offs behind each definition. - Design, build, and validate statistical and machine learning models — forecasting, causal inference, segmentation, and anomaly detection — that power those metrics and surface competitive shifts. - Pull together disparate third-party transaction-panel data and internal Amazon signals into coherent, reproducible modeling pipelines that leadership can trust for recurring reporting. - Translate ambiguous business questions ("are we losing ground in grocery?") into the right metric, the right model, the right cut of data, and a clear, defensible answer. - Productionize models and analyses so they run reliably as recurring mechanisms, partnering with data engineers to scale and automate. - Produce monthly flash reports and deep-dive narratives that turn models and metrics into decisions for CXBT and business-line leadership. - Set the standard for analytical and modeling rigor on the team — methodology reviews, documentation, and guardrails against misleading cuts. - Mentor and technically uplift other scientists and BIEs on the team — reviewing modeling approaches and raising the bar on rigor (e.g., partnering with our Data Scientist on the MatchIQ model to strengthen methodology and validation). About the team CXBT is a group of diverse functions dedicated to understanding, improving, and influencing customer experience globally, across all of Amazon. We are builders who develop products, services, and data-driven approaches that shape offerings for nearly every Amazon business and customer type — consumers, developers, sellers, brands, employees, investors, streamers, and gamers. We work backwards from customer needs, combine technical and non-technical methods, and track industry and business trends. Our roles span Product Managers, Data Scientists, Economists, Business Intelligence Engineers, Data Engine, Applied Scentist, and Product Manager.

We enable massive advertising programs, generating billions of impressions decorated with rich representations of customer state. The major challenges we are solving include integrating petabyte-scale distributed retail systems into a singular service to synthesize e-commerce data into measurement and optimization models. The successful candidate will have a strong technical background in ML and causal inference, experience with large scale data ML models, high judgment to drive business impact, an appreciation for white-space, and success building and developing high-performing teams. Key job responsibilities • Lead, hire, mentor, and develop a team of scientists and engineers, fostering a culture of innovation, scientific rigor, and operational excellence. • Set the technical vision and roadmap for the team’s measurement and modeling initiatives, aligning with business priorities. • Partner with senior leadership to define measurement strategies and translate business needs into science roadmaps and deliverables. • Guide the team in applying ML, statistics, and econometrics to develop, analyze, and productionize prototype models. • Drive the design and analysis of large-scale online experiments to validate models and measure impact. • Foster collaboration across science teams through peer-review processes, publishing research internally and at industry conferences. • Establish scalable, efficient, and automated processes for large-scale model development, validation, and implementation.
