• Model Development: Design and deliver new models and algorithms across forecasting, placement, inventory targets, safety stock, and exits to optimize cost, speed, and customer experience.
• Optimization & Machine Learning: Apply advanced techniques in optimization, probabilistic forecasting, and ML to improve efficiency and resilience across Walmart’s global network.

• Collaboration & Influence: Translate science into strategy, working with Merchandising, Supply Chain, and Tech partners to align on priorities and deliver measurable impact.
• Future-Focused Capabilities: Advance scenario modeling, dynamic inventory placement, multi-echelon optimization, and placement orchestration for omni-channel fulfillment.

What you'll Bring...

• Strong expertise in applied data science and advanced analytics (optimization, forecasting, simulation, machine learning)
• Comfortability operating at both strategic and technical depth — from building models to influencing enterprise priorities
• Experience simplifying complex science for senior leaders and business partners to drive adoption and decision-making
• Ability to excel in ambiguous, high-pressure environments with multiple stakeholders and competing priorities
• A passion for solving global-scale inventory optimization challenges that directly improve customer experience
• MBA, MS, or PhD in Operations Research, Industrial Engineering, Applied Mathematics, Statistics, Operations Management, or Supply Chain Management
• Experience implementing data science models using modern programming languages (e.g., Python, PySpark, R) and using large dataset mining tools (e.g., SQL)
• Experience with advanced analytical modeling tools, network optimization, and long-range planning
• Extensive experience or knowledge of eCommerce, retail and supply chain domains and related information systems — search, impressions, conversion, distribution/transportation, sourcing, planning, manufacturing, and inventory management
• Retail industry experience
