Description

Contractor, Data Science and Ops Research Scientist - Supply Chain Planning COE

Key Responsibilities

Forecasting - Data Science

Develop and deploy time-series forecasting and machine learning models to improve demand planning across products, regions, and business segments.

Build ML solutions for demand sensing, anomaly detection, predictive analytics, and forecast improvement.

Perform feature engineering, model development, validation, and statistical analysis using large-scale supply chain data.

Design and implement end-to-end data science pipelines, from data preparation through deployment, monitoring, and continuous improvement.

Evaluate model performance using accuracy, bias, SMAPE, forecast attainment, and other relevant metrics.

Collaborate with multiple teams to productionize and scale data science solutions.

Inventory Optimization - MEIO Model Development & Ownership

Lead the end-to-end development and ownership of Multi-Echelon Inventory Optimization (MEIO) models across retail stores, distribution centers, hubs, and customer-facing nodes.

Translate business requirements, inventory policies, service objectives, and operational constraints into mathematical optimization models and scalable decision-support solutions.

Design and maintain model objectives, assumptions, constraints, and optimization logic to balance service, inventory, safety stock, leadtime variability, capacity and cost.

Own model lifecycle management, including design, development, validation, deployment, monitoring, and recalibration as business conditions evolve.

Partner with business stakeholders to align model outputs with planning strategies, inventory policies, and service objectives.

Optimization & Solver Engineering

Develop mathematical optimization models using Gurobi or comparable commercial solvers.

Apply techniques including linear programming, mixed-integer programming, scenario analysis, and uncertainty-aware optimization.

Improve model performance through reformulation, decomposition, heuristics, and solver parameter tuning.

Establish practices for reproducible testing, scenario analysis, benchmarking, and validation to ensure optimization recommendations are practical and implementable.

Data, Operationalization & Adoption

Develop and maintain SQL-based ETL processes and data pipelines supporting optimization models, scenario analysis, and production deployment.

Partner with data engineering teams to ensure the quality, availability, and integrity of model inputs, including demand variability, lead times, network structure, service policies, and operational constraints.

Establish governance, monitoring, and documentation to ensure model outputs are accurate, explainable, auditable, and production-ready.

Support algorithmic planning and predictive scenario analysis using supply chain planning systems and advanced analytics tools.

Drive adoption through user training, workshops, documentation, and ongoing support for planners and other stakeholders.

Required Qualifications

6+ years of experience in Operations Research, supply chain optimization, data science and forecasting, including direct ownership of MEIO or comparable inventory optimization solutions and demand forecasting models.

Demonstrated ability to translate business requirements, planning policies, and operational constraints into mathematical optimization and analytical solutions.

Experience developing and deploying optimization models using Gurobi preferred, or comparable commercial solvers.

Strong understanding of multi-echelon inventory optimization, including safety stock, service levels, demand and lead-time variability, replenishment policies, and network topology.

Strong foundation in data science and forecasting, including time-series and ML-based forecasting techniques such as ARIMA, Prophet and XGBoost.

Experience applying machine learning and predictive analytics to real-world supply chain problems.

Experience with stochastic optimization, robust optimization, scenario planning, or simulation.

Proficiency in Python and optimization frameworks such as gurobipy, Pyomo and similar OR Tools, with strong software development practices.

Advanced SQL skills, including ETL, data transformation, and development of model-ready datasets.

Experience with commercial MEIO platforms or comparable in-house optimization solutions.

Strong understanding of supply chain planning, inventory management, and S&OP processes.

Skills & Competencies

Strong technical expertise in mathematical optimization, solver tuning, model validation, and forecasting.

Strong data science skills, including time-series forecasting, machine learning, feature engineering, and model evaluation.

Ability to connect data, models, business processes, and operational outcomes to develop scalable solutions.

Strong leadership and communication skills, with the ability to influence stakeholders and explain technical concepts to diverse audiences.

Ability to operationalize solutions through governance, monitoring, documentation, and user adoption.

Strong project management and problem-solving skills with the ability to manage complex, cross-functional initiatives.
