Careers

The Central Science Team within Amazon’s People Experience and Technology org (PXTCS) uses economics, behavioral science, statistics, and machine learning to proactively identify mechanisms and process improvements which simultaneously improve Amazon and the lives, well-being, and the value of work to Amazonians. We are an interdisciplinary team, which combines the talents of science and engineering to develop and deliver solutions that measurably achieve this goal. We are looking for an Applied Scientist to build models at the intersection of prediction, causal inference, and optimization. These models are the science foundation for operational workforce planning at Amazon's scale — predicting who stays, who shows up, and suggesting which levers Amazon should use to ensure smooth business operations and the best employee experience. As an Applied Scientist, you will own the forecasting and prediction models. Your forecasts go straight into planning cycles that commit real hiring, so accuracy, calibration, and being able to explain a number to business partners all matter for success. You will work with other scientists and economists on the team, so you will need an interdisciplinary mindset and an eye on how causal inference and forecasting interact. You will also collaborate with engineers to put models into production, so you should be comfortable owning a live system and not only an analysis. Key job responsibilities - Design and develop forecasting and prediction models that feed Amazon's workforce planning and optimization systems. - Build models and algorithms from prototype to production-level systems, and support them once planners depend on them. - Partner with the team's economists to connect forecasts with causal estimates of policy levers. - Extend models to new sites, shifts, and business lines as the platform expands. - Translate ambiguous business problems into modeling approaches, and drive the technical design with planning, engineering, and operations partners. A day in the life - Analyze data to investigate a forecast miss or model performance, and identify improvements - Brainstorm modeling approaches with fellow scientists and economists on the team - Build and backtest new features for your model - Run a simulation or experiment to evaluate your model's performance - Meet with planning, compensation, or finance partners to review requirements, data, design, or other project decisions - Review code changes or a design document from a fellow scientist or engineer - Write and present a document covering method, results, and recommendations

Worldwide Global Selling has been helping individuals and businesses increase sales and reach new customers around the globe. Today, more than 50% of Amazon's total unit sales come from third-party selection. The Global Selling team in China is responsible for recruiting local businesses to sell on Amazon's 19+ overseas marketplaces and supporting local Sellers' success and growth on Amazon. Our vision is to be the first choice for all types of Chinese business to go globally. The Worldwide Global Selling Analytics, Intelligence, and Technology (WWGS-AIT) team serves as the research, automation, and insight arm of the International Seller Service data hub, enabling rapid delivery of growth insights through strategic investments in regional data foundations, self-service business intelligence solutions, and artificial intelligence tools. The WWGS-AIT team is positioned to establish AI-ready foundational capabilities across the WWGS organization while maintaining excellence in business insight generation, and self-service BI/AI application development. WWGS-AIT is looking for a Data Scientist to design and build seller-facing AI agents that turn our AI-ready data foundation into intelligent, conversational experiences for Amazon's global sellers. You will own the intelligence layer of these agents end-to-end, from modeling and retrieval to evaluation and launch, working alongside applied scientists, data engineers, and the Seller Assistant platform team to put trustworthy AI directly into sellers' hands. Key job responsibilities - Design, build, and iterate seller-facing AI agents (LLM-powered) that help Chinese sellers grow globally, reasoning over WWGS-AIT's AI-ready data foundation and knowledge base. - Develop the intelligence layer of agents: retrieval-augmented generation (RAG) over our knowledge management system, tool-use / function-calling orchestration, prompt engineering, and model fine-tuning or adaptation where needed. - Ground agent responses in standardized metrics and unified seller profiles to guarantee consistency and accuracy across agents; design and enforce guardrails that prevent hallucination and protect sensitive, compliance-restricted data. - Build rigorous evaluation frameworks (golden datasets, offline evaluation, and online experimentation) to measure and continuously improve agent quality, safety, and seller impact. - Develop seller-intelligence models (segmentation, entity resolution / One-ID, ranking and recommendation) that power personalized agent experiences. - Partner with WWGS Tech and the Seller Assistant platform team to productionize agents and tools (e.g., via MCP), defining the model and intelligence contract while engineering operates the runtime. - Collaborate with business, product, and cross-functional partners to translate seller pain points into agent capabilities and measurable business outcomes. - Stay current with advances in GenAI and agentic systems, and bring applied research into production.
