Sr. Data Scientist , Companion Product & Servi (ComPAS)

ComPAS Business Insights sits at the intersection of pricing, marketing, and consumer science for Amazon"s Companion Products & Services portfolio; spanning Accessories, Pre-Owned Business (POB), and Trade-In (TI). AI is fundamentally changing how we solve these problems. As a Sr. Data Scientist, you will drive that transformation: building advanced ML models and AI-powered tools that automate decision science at scale, turning complex pricing, targeting, and segmentation challenges into intelligent, self-improving systems.

You will partner with product, marketing, finance, and engineering leaders to translate ambiguous problems into production-ready ML systems and AI-powered tools. Your work will span pricing science, consumer behavior analysis, marketing targeting, propensity score development, and customer segmentation - always with an eye toward how generative AI and foundation models can accelerate, scale, or reimagine the solution.

Key job responsibilities

Key Job Responsibilities

• Own the full lifecycle of model development - from problem framing and exploratory analysis through feature engineering, model design, deployment, and continuous improvement.
• Oversees the development of pricing science models, including price elasticity estimation, promotional effectiveness measurement, and optimal pricing recommendations across Accessories, POB, and TI product lines.
• Build and refine propensity models and customer segmentation frameworks that enable precision marketing targeting and personalized customer engagement.
• Conduct consumer behavior analysis to uncover purchase patterns, cross-sell opportunities, and drivers of performance across the ComPAS portfolio.
• Leverage generative AI and LLMs (e.g., Amazon Bedrock, foundation models) to build intelligent tools that automate insights generation, scale analytical workflows, and solve problems that were previously intractable.
• Identify and execute opportunities to optimize and automate existing analytical and scientific processes -ntransforming manual, repetitive work into scalable AI-powered pipelines.
• Design and run rigorous experiments (A/B testing, causal inference, synthetic control) to measure impact and guide strategic decisions on pricing, marketing, and product.
• Build data-driven business cases to prioritize science and AI initiatives, demonstrating measurable impact on revenue and customer outcomes.
• Contribute to the broader science community by mentoring data scientists and publishing technical work in internal and external forums.

A day in the life

Your mornings start with decision science - framing a pricing or targeting problem, writing Python/SQL to prototype a model, or stress-testing a segmentation approach. Afternoons shift to AI tool-building: experimenting with foundation models, designing automation pipelines, or collaborating with engineers on deployment architecture. Between deep work blocks, you"re leading problem-framing sessions with PMs, and business leaders, demoing AI prototypes to stakeholders, or hosting a Lunch & Learn that sparks the next automation idea across the team.
