(USA) Distinguished, Data Scientist
About The Position
We are hiring a Distinguished Data Scientist to lead the design and development of Walmart Connect's next-generation ads incrementality measurement platform. We are looking for a scientist with rare depth in causal inference, incrementality and RCT experimentation who thrives on doing the hard technical work, not just directing it. You will own the methodology end-to-end, partner with engineering and product to carry solutions into production, and serve as the team's go-to authority on the hardest measurement problems. You will help set the bar for what rigorous, causally grounded ads measurement looks like at Walmart Connect. The team advances advertising measurement by applying innovative data science and machine learning techniques. It focuses on causal inference and incrementality experimentation to deliver actionable insights.
Requirements
- PhD or Master's in Statistics, Economics, Econometrics, Computer Science, or a related quantitative field — PhD strongly preferred
- 8+ years in data science or quantitative research
- ads industry experience preferred
- Deep, specialized expertise in causal inference and/or incrementality-based optimization — Randomized control trials, PIE model, instrumental variables, uplift DNN, regression discontinuity and related methods
- Strong command of experiment design at scale — power analysis, variance reduction, interference and spillover handling, and bias correction
- Proficiency in Python and SQL for large-scale data data analysis and experience with distributed data platforms (Spark, BigQuery, or equivalent)
- Strong statistical foundations and machine learning knowledge
- Bachelor’s degree in Statistics, Economics, Analytics, Mathematics, Computer Science, Information Technology or related field and 6 years' experience in an analytics related field.
- Master’s degree in Statistics, Economics, Analytics, Mathematics, Computer Science, Information Technology or related field and 4 years' experience in an analytics related field.
- 8 years' experience in an analytics or related field.
Nice To Haves
- Data science, machine learning, optimization models
- PhD in Machine Learning, Computer Science, Information Technology, Operations Research, Statistics, Applied Mathematics, Econometrics
- Publications or active peer reviewer in related journals or conference
- Successful completion of one or more assessments in Python, Spark, Scala, or R
- Using open source frameworks (for example, scikit learn, tensorflow, torch)
- We value candidates with a background in creating inclusive digital experiences, demonstrating knowledge in implementing Web Content Accessibility Guidelines (WCAG) 2.2 AA standards, assistive technologies, and integrating digital accessibility seamlessly.
- The ideal candidate would have knowledge of accessibility best practices and join us as we continue to create accessible products and services following Walmart’s accessibility standards and guidelines for supporting an inclusive culture.
Responsibilities
- Design and implement large-scale causal inference methodologies to measure the true incremental lift of advertising across campaigns, channels, and segments
