Data Scientist II, EU Prime and Marketing Analytics & Science (PRIMAS)

Job Title: Data Scientist II, EU Prime and Marketing Analytics & Science (PRIMAS) Company: Amazon Job Category: Data Science Roles & Responsibilities: The EU Marketing \& Prime organization is looking for a Data Scientist to join the PRIMAS team. This role sits at the intersection of applied statistics and large\-scale analytics — you'll design experiments and causal models, and also own the data pipelines, metrics, and reporting infrastructure that make those results usable across the business. Key job responsibilities * Design and implement scalable, statistically rigorous experiments (A/B, geo, holdout, quasi\-experiments) to measure marketing incrementality across channels. * Perform power analysis and minimum detectable effect (MDE) calculations to determine experiment sample sizes, durations, and design trade\-offs before launch. * Build causal and treatment\-effect models that produce conversion and valuation signals consumed by downstream bidding and budgeting systems. * Building the ETL, metric definitions, and datasets that make results scalable, extensible, and repeatable rather than one\-off analyses. * Develop measurement frameworks that quantify the true, platform\-independent contribution of marketing over time, and build the dashboards and reporting that keep those metrics visible to the business. * Apply statistical, mathematical, and machine learning techniques to solve ambiguous business problems where the right approach isn't obvious. * Analyze experiment results for validity — inspecting distributions, checking for sample ratio mismatch, exploring covariate balance, and tracking down the source of anomalies. * Communicate experiment design, results, and trade\-offs clearly to business and leadership audiences, including inputs into business reviews, and influence decisions and technical direction across teams. * Establish scalable, repeatable processes and best practices for experiment design, data modeling, and analysis.
