This role focuses on solving complex, large-scale mathematical problems to inform strategic and operational decisions, including pricing, inventory, supply chain, and marketing optimization.

You will work at the intersection of data, mathematical modeling, and decisioning systems, translating business problems into formal optimization frameworks and delivering production‑ready solutions. This role requires deep hands‑on experience in operations research (OR), including building and solving large‑scale optimization models, alongside strong data engineering and software skills to operationalize those solutions. This role will report to the Sr. Director, Data Science.

• Formulate decision problems as mathematical optimization models (LP, MILP, MINLP), translating business constraints and objectives into structured frameworks
• Design and implement large‑scale optimization models, solving complex problems involving thousands to millions of variables and constraints
• Leverage solvers such as Gurobi (preferred) or equivalent tools to build high‑performance solutions, including model tuning and performance optimization
• Develop end‑to‑end decision systems, integrating optimization outputs into production workflows and business processes
• Collaborate with business stakeholders to define objective functions, constraints, and trade‑offs, ensuring solutions align with real‑world decision‑making
• Evaluate solution quality through scenario testing, sensitivity analysis, and stress testing of optimization results
• Scale and product ionize models, including API development, automation, monitoring, and retraining workflows
• Build and maintain data pipelines to support optimization models, ensuring data quality, availability, and performance at scale
• Communicate model structure, assumptions, and results clearly to leadership, translating complex math into actionable business insights

• Bachelor's Degree in Operations Research, Industrial Engineering, Applied Mathematics, Computer Science, or related field or equivalent years of experience
• Master's Degree in Operations Research, Industrial Engineering, Applied Mathematics, Computer Science, or related field or equivalent years of experience

• Hands‑on experience with Gurobi (strongly preferred) or similar solvers (CPLEX, OR‑Tools, etc.)
• Proven experience building and deploying large‑scale mathematical models (LP, MILP, etc.) in production environments
• Ability to design and maintain data pipelines for large‑scale modeling workflows and experience working with large, complex datasets, including feature engineering and data validation
• Proficiency in Python and SQL, with emphasis on scalable, maintainable code
• Familiarity with cloud environments (AWS, Azure, GCP) for scalable execution

• Paid Time Off (PTO)
• Generous store discounts
• Health care plans (medical, prescription, dental, vision)
