Position Summary...

What you'll do...
We are seeking a Staff Data Scientist to serve as a technical anchor for the Omni Price Recommendation Engine. You will lead the scientific design and end-to-end execution of high-frequency pricing systems that balance competitive positioning with long-term margin health. This is a high-visibility role requiring a deep mastery of Causal Inference, Reinforcement Learning, and Elasticity Modeling.

What You'll Do

• Design and deploy prescriptive ML models to address high-impact pricing and markdown needs, ensuring alignment with Walmart's Global Tech strategy and EDLP integrity.
• Perform elasticity analysis across large data sets and category segments to empower data-driven pricing decisions.
• Own the E2E Price Recommendation lifecycle, including scoping, feature engineering, causal modeling, experimentation (A/B testing), and ongoing performance optimization.
• Develop advanced pricing and optimization solutions using:
• Causal Inference & Elasticity: Identification of treatment effects beyond simple log-log approaches (Double ML, Instrumental Variables, Uplift modeling).
• Optimization & Reinforcement Learning: Multi-armed bandits, Deep RL (PPO, DQN) for sequential decision-making, and constrained optimization.
• Deep Learning: Modern architectures for demand sensing and price-response curves.
• Uncertainty Quantification: Bayesian approaches and conformal prediction to manage the risk of price changes.
• Build explainable pricing systems: Provide model interpretability and stakeholder-facing narratives on "why" a price recommendation was made (e.g., competitor move vs. inventory health).
• Apply graph-based modeling to capture cannibalization and halo effects across product hierarchies and spatial locations (GNNs, temporal graphs).
• Establish strong evaluation and monitoring: Backtesting against historical price changes, drift detection, and calibration of price-response curves.
• Drive best practices in AgentOps: Build Agentic workflows to enable chat-based price explainability and "what-if" scenario planning for Merchants.
• Collaborate and Mentor: Partner with Product, Business, and Engineering to set technical direction and mentor the next generation of MLEs.

What You'll Bring

• 8+ years in Data Science / Applied ML (or PhD + 5 years), with deep hands-on exposure to pricing, elasticity, or causal modeling.
• Demonstrated experience delivering production-grade optimization models with measurable financial outcomes (e.g., Margin lift, Inventory turnover).
• Strong knowledge of pricing dynamics: Seasonality, competitor indexing, promotional impact, regime changes, and price-point psychology.
• Hands-on experience with deep learning frameworks (PyTorch or TensorFlow) and modern architectures for decision-focused AI.
• Practical experience with Explainable AI (XAI) and communicating complex model reasoning to non-technical business stakeholders.
• Excellent coding skills in Python; strong grasp of software engineering fundamentals (testing, CI/CD, MLOps).

Preferred Qualifications

• Experience with Causal Inference & Decision Science: Impact estimation, counterfactuals, and policy evaluation.
• Advanced Graph Learning: Using GNNs to model cross-item elasticity and substitution patterns.
• Large-scale Data/Compute: Experience with Spark, Feature Stores, and distributed training in a cloud environment (GCP/Azure).
• Building Human-Centered AI: Dashboards for "driver decomposition" and "why the price changed" analysis.
• Agentic Frameworks: Experience deploying LLM-based agents to act as intermediaries between complex models and business users.
