Responsibilities

• As an Applied Scientist on this team, you will build machine learning and deep learning models on large-scale global data to simulate customer behavior across the business.
• You will partner closely with business, finance, engineering, and science stakeholders to take ideas from concept and prototype through to production.
• Build models that simulate customer behavior to answer counterfactual "what-if" questions that guide major content and product investment decisions.
• Apply deep learning, reinforcement learning, causal inference, and experimental design to large-scale customer data to model how customers respond to change.
• Design and prototype agentic AI systems and other novel ML approaches and research new methods to improve the accuracy and scale of our models.
• Validate and calibrate models against real-world randomized experiments, and partner with software engineers to deliver scalable, production-ready systems.
• Translate model outputs into clear recommendations and communicate results to business, finance, and science stakeholders through both technical papers and business-facing documents.
• About the team
• The Prime Video Science team is a multidisciplinary group of applied scientists, data scientists, economists, and engineers.
• We take on some of the hardest research questions in the business, and our work carries visibility up to the CFO/CEO level.
• We pursue ambitious research at the intersection of machine learning, AI, and causal inference, turning that research into innovations that improve customer experience and strengthen business profitability.
• Few science teams get to work on problems this hard and this impactful; if that combination excites you, we'd love to talk.
