You will design experiments where possible and robust observational studies where they are not, helping us understand the incremental effect of product, algorithmic, and policy changes on outcomes such as GMV, profitability, and operational efficiency. Working closely with Product, Engineering, Analytics, Applied Science and business stakeholders, you will turn ambiguous questions into clear evaluation strategies, reliable evidence, and better product decisions.
