DescriptionWe are seeking a senior scientist to develop new and enhanced statistical models for A/B testing large experiments at scale. Our team owns "causal inference as a service" for the Pricing and Promotions organization; we run A/B tests on new pricing, promotions, and pricing/promotions CX algorithms and, where experimentation is impractical, conduct observational causal studies.The scientist for this role will help explore new randomization methodologies (e.g. cluster and stratified strategies, as well as switchback or crossover designs) as well as build cutting-edge solutions to newer paradigms such as bipartite experimentation. Research opportunities also exist for intra-experiment and inter-experiment spillover effect measurement.Key job responsibilitiesWe are seeking a senior scientist to help envision, design, and build the next generation of pricing, promotions, and pricing/promotions CX for Amazon. On our team, you will work at the intersection of economic theory, statistical inference, and machine learning to design and implement in production new statistical methods for measuring causal effects of an extensive array of business policies.This position is perfect for someone who has a deep and broad analytic background, is passionate about using mathematical modeling and statistical analysis to make a real difference. You should be familiar with modern tools for data science and business analysis and have experience coding with engineers to put projects into production. We are particularly interested in candidates with research background in experimental statistics.A day in the life
Discuss with business problems with business partners, product managers, and tech leaders
Brainstorm with other scientists to design the right model for the problem at hand
Present the results and new ideas for existing or forward looking problems to leadership
Dive deep into the data
Build working prototypes of models
Work with engineers to implement prototypes in production
Analyze the results and review with partners
About the teamWe are a team of scientists who design and implement the econometrics and statistics powering pricing, promotions, and pricing/promotions CX.Basic Qualifications
