Sr. Applied Scientist, Supply Chain Optimization Technologies

Amazon is looking for an Sr. Applied Scientist to help build next generation selection/assortment systems. On the Selection team within the Supply Chain Optimization Technologies (SCOT) organization, we own the selection of the products that Amazon offers world-wide and what is prioritized for our fastest delivery speeds. The selection is generated with a series of Machine Learning (ML) and optimization models accounting for profitability, customer intents, and limited warehouse space. We build tools and systems that enable our partners and business owners to scale themselves by leveraging our problem domain expertise, focusing instead on introspecting our outputs and iteratively helping us improve our models rather than hand-managing their assortment. We partner closely with our business stakeholders as we work to develop state-of-the-art, scalable, automated selection management systems.

As a Sr. Applied Scientist, you will work with software engineers, product managers, and business teams to understand the business problems and requirements, distill that understanding to crisply define the problem, and design and develop innovative solutions to address them. Our team is highly cross-functional and employs a wide array of scientific tools and techniques to solve key challenges, including supervised and unsupervised machine learning, large language models, linear, nonlinear, and non-convex optimizations, reinforcement learning, causal inference, and experiment designs. Some critical research areas in our space include modeling substitutability between similar products, complementarity and basket building, measuring speed sensitivity of products through experiments, optimizing assortment under operational and capacity constraints, and supply and demand forecasting.
