Sr. Research Scientist

Job ID: 1639264 | Amazon Dev Centre Canada ULC


Are you an exceptional science leader who is interested in building innovative products that optimize a global supply chain? Within Amazon's Supply Chain Optimization Technology (SCOT) team, the Capacity team owns the systems that help decide where to place hundreds of millions of units of inventory a week, ensuring that we are optimizing capacity across our supply chain globally to get inventory closer to customers. We are looking for a Sr RS that enjoys solving complex supply chain problems and has a deep knowledge of analyzing large-scale data using optimization and machine learning, leading the team to success. As a leader in SCOT, you will own and drive improvements in the Amazon's supply chain, continually raising the bar by delivering Supply Chain efficiencies. There are no textbook solutions to the problems we are solving and very few attempts have been made to solve at Amazon's scale, which necessitates an analytical thinking to solve problems.

The ideal candidate will be a proven sciences leader who is a self-starter comfortable with ambiguity, demonstrates strong attention to detail, and thrives in a fast-paced environment. You will have excellent business, technical, analytical and data dive-deep skills. You are effectively able to work with product, business and technology leaders to define and prioritize key customer problems, build data acquisition and integration pipelines to create data sets, develop statistical and machine learning models and deliver analyses and insights that answer these problems. You will have strong quantitative modeling skills and expertise using data mining and statistical analyses at web-scale to coach and guide the team to produce actionable insights and recommendations. You will lead by example and are comfortable taking on projects and delivering results as an individual contributor.
