Senior Research Scientist, Fulfillment by Amazon (FBA) Science

The Fulfillment by Amazon (FBA) Science team is looking for a passionate curious and creative Senior Research Scientist with deep expertise in statistical modeling machine learning and large language models (LLMs) and a proven record of solving complex forecasting problems at scale. Our team sits at the intersection of supply chain science seller behavior modeling and policy analytics building the forecasting backbone that powers FBAs shipment creation inbound arrival planning and inventory management.
We develop science solutions that predict seller shipment creation patterns model inbound arrival timing and quantity and forecast inventory levels across Amazons fulfillment network. A key challenge we tackle is understanding how seller behavior changes driven by market dynamics FBA policy updates and incentive structures and how these behavioral shifts propagate into forecasting signals. We aim to build forecasting systems that are not only accurate but also explainable and actionable for both internal stakeholders and sellers.
To do so we build and innovate science solutions at the intersection of statistical learning machine learning econometrics operations research and generative AI. As a Senior Research Scientist you will propose and deploy solutions drawing from a range of scientific areas including time-series forecasting causal inference Bayesian methods LLMs and deep learning. This role has high visibility to senior Amazon business leaders and involves close collaboration with scientists engineers and product teams to integrate scientific work into production systems.


Key job responsibilities
- As a senior member of the FBA Science forecasting team play an integral role in building and advancing Amazons FBA shipment creation inbound arrival and inventory forecasting systems.
- Research and develop statistical models ML models and LLM-based solutions to forecast seller shipment creation behavior inbound arrival patterns and downstream inventory levels across the FBA network.
- Model and quantify the impact of seller behavior changes and FBA policy updates (e.g. capacity limits fee structures inbound placement policies) on forecasting accuracy and develop robust forecasting approaches that adapt to these dynamics.
- Build explainability frameworks for forecasting models enabling science teams product managers and business stakeholders to understand model drivers diagnose forecast errors and trust model outputs.
- Define a long-term science vision and roadmap for the forecasting team driven fundamentally by customer and seller needs translating those directions into specific plans for research and applied scientists as well as engineering and product teams.
- Drive and execute forecasting science projects end-to-end: from ideation analysis and prototyping through to development deployment metrics definition and monitoring.
- Review and audit modeling processes and results for other scientists both junior and senior.
- Advocate the right science solutions to business stakeholders engineering teams and executive-level decision makers.


A day in the life
In this role you will be a technical leader in forecasting science with significant scope impact and high visibility. Your solutions will directly influence billions of dollars in inventory decisions inbound logistics planning and seller experience across Amazons global fulfillment network. As a senior scientist on the team you will be involved in every aspect of the process from idea generation business analysis and scientific research through to development and deployment of advanced forecasting models giving you a real sense of ownership.
From day one you will work with experienced scientists engineers and product designers who are passionate about what they do. You are expected to make decisions about modeling methodology technology choices and explainability approaches. You will strive for simplicity and demonstrate judgment backed by mathematical rigor. You will also collaborate with the broader decision and research science community at Amazon to broaden the horizon of your work and mentor engineers and scientists. We are seeking someone who wants to lead projects requiring innovative thinking and deep technical problem-solving skills to create production-ready forecasting solutions. The candidate will need to be entrepreneurial wear many hats and work in a fast-paced high-energy highly collaborative environment.


About the team
Fulfillment by Amazon (FBA) is a service that allows sellers to outsource order fulfillment to Amazon enabling them to leverage Amazons world-class fulfillment infrastructure to deliver on the Prime promise. FBA ships more than half of all products offered on Amazon and our science team is at the heart of making that possible. The FBA Science forecasting team focuses on predicting seller shipment creation inbound arrival and inventory dynamics providing the signals that drive capacity planning inbound logistics and inventory positioning across the network. We work full-stack from foundational forecasting models to seller-facing explainability tools. Our culture is centered on rapid prototyping rigorous experimentation and data-driven decision-making.

- PhD or Masters degree and 5 years of quantitative field research experience
- 3 years of investigating the feasibility of applying scientific principles and concepts to business problems and products experience
- Experience with big data technologies such as AWS Hadoop Spark Pig Hive etc.
- Experience communicating qualitative research methods and findings to non-qualitative researchers
- Experience in standard machine-learning and statistical modeling tools and techniques (e.g. random forests gradient-boosted regression LASSO logistic regression)
- Proficiency working with Python and other high-level languages (Java/C/Scala) with at least 5 years of coding experience

- Extensive knowledge and practical experience in several of the following: time-series forecasting Bayesian methods causal inference deep learning LLMs and reinforcement learning
- Experience building model explainability frameworks for production forecasting systems
- Practical experience building and evaluating deep learning models using major frameworks (e.g. PyTorch TensorFlow or similar)
- Significant peer-reviewed scientific contributions in premier journals and conferences
