Position Summary...

About Walmart Business
Walmart Business is a rapidly growing omnichannel platform designed to serve businesses, nonprofits, and government agencies at scale. By combining Walmart’s unmatched assets with purpose-built B2B experiences, we are redefining how organizations purchase and operate.
This is a unique opportunity to shape foundational decision-making in a high-growth business while leveraging the scale and complexity of the world’s largest omnichannel retailer.

What you'll do...

As a Principal Data Scientist, you will serve as a technical authority in causal inference, experimentation, and decision science, influencing strategy across Product, Business, and Executive leadership.

• Define and lead the causal measurement strategy for major product, pricing, and operational initiatives, ensuring decisions are grounded in robust causal evidence rather than correlation.
• Design and evaluate large-scale experimentation frameworks, including A/B testing, sequential experimentation, and quasi-experimental designs, to measure true business impact.
• Develop and apply advanced causal and statistical models, such as:
  • Treatment effect and uplift models
  • Difference-in-differences and synthetic controls
  • Propensity score and matching methods
  • Instrumental variables and observational causal techniques
• Translate complex causal findings into executive-ready insights, clearly communicating assumptions, limitations, uncertainty, and business implications.
• Partner directly with senior business and product leaders to frame ambiguous, high-stakes problems, define learning agendas, and determine the right analytical or experimental approach.
• Connect leading indicators to lagging outcomes, demonstrating how specific product and operational levers causally impact revenue, conversion, retention, and customer experience.
• Influence roadmap and investment decisions by identifying high-ROI opportunities and quantifying trade-offs through experimentation and modeling.
• Set technical standards and best practices for experimentation and causal analysis, mentoring senior data scientists and raising the overall analytical maturity of the organization.

What You’ll Bring

• Deep expertise in causal inference and experimentation, with a strong track record of applying these methods to real-world business decisions.
• Advanced modeling and statistical skills, including causal modeling, experimental design, and large-scale observational analysis.
• Strong technical proficiency in SQL, Python, and/or R, with experience working on complex, high-volume data systems.
• Strategic and systems thinking, with the ability to connect business objectives, product strategy, and analytical methods end-to-end.
• Executive influence without authority, able to shape decisions through rigor, clarity, and credibility rather than formal management responsibility.
• 10+ years of experience in data science, applied research, or advanced analytics roles, operating at principal or staff-level scope.
• Retail, eCommerce, or marketplace experience is a plus, including pricing, supply chain, merchandising, or digital platforms.
