Job Summary

The Applied Machine Learning Scientist develops, validates, and operationalizes machine-learning and statistical solutions that improve supply-chain decisions. The role is primarily focused on demand forecasting, inventory optimization, and related decision-support problems. The successful candidate will combine strong applied modelling skills with the ability to work independently in Python and SQL, build reliable model-ready datasets, and translate experiments into maintainable production solutions. The role works closely with the Manager of Advanced Analytics & Machine Learning, and with business and technical stakeholders to ensure solutions are measurable, explainable,scalable, and aligned with operational constraints.

Key Responsibilities:

Applied Modelling & Experimentation

· Develop and improve forecasting and optimization models for supply-chain and operational use cases.

· Perform feature engineering, model selection, hyperparameter tuning, error analysis, and structured experimentation.

· Design evaluation frameworks using time-aware validation, backtesting, and business-relevant performance metrics.

· Apply appropriate statistical and machine-learning methods, including time-series analysis, regression, probabilistic modelling, and tree-based models.

· Investigate model bias, uncertainty, drift, and failure modes, and recommend practical improvements.

Productionization & Data Workflows

· Write clear, maintainable, production-quality Python and SQL.

· Build and maintain scalable model workflows and model-ready datasets using Snowflake and collaborative analytics environments such as HEX.

· Operationalize model outputs through reliable data pipelines, versioning, monitoring, retraining, and alerting practices.

· Contribute to shared coding, testing, documentation, and model-governance standards.

Project Execution & Collaboration

· Own defined modelling workstreams from problem formulation through validation, implementation, and business adoption.

· Partner with Supply Chain, IT, Data, and other stakeholders to define objectives, constraints, and success measures.

· Present technical findings clearly and translate model results into actionable business recommendations.

· Evaluate emerging methods and technologies based on their practical value to current business problems.

Qualifications & Experience

Education & Experience

·Master's degree in Data Science, Statistics, Computer Science, Mathematics, Operations Research, or a related quantitative field; or a bachelor's degree with equivalent applied machine-learning experience.

 · Three or more years of applied data-science or machine-learning experience, including meaningful ownership of a production modelling solution.

 · Demonstrated experience taking a modelling problem from raw data through feature engineering, validation, implementation, and performance review.

Required Technical Skills

· Strong Python skills, including practical use of pandas, NumPy, scikit-learn, and gradient-boosting libraries such as LightGBM or XGBoost.

 · Strong SQL skills and the ability to independently create, validate, and troubleshoot large analytical datasets. · Strong foundation in statistics, experimental design, time-series validation, model evaluation, and leakage prevention.

· Ability to design solutions that respect real operational constraints and balance model performance with maintainability and adoption.

 · Clear written and verbal communication with both technical and business audiences.

Preferred Assets

 · Experience with demand forecasting, inventory, supply-chain analytics, manufacturing, or operations research.

· Experience with Snowflake or another modern cloud data platform. · Familiarity with Git, automated testing, model versioning, monitoring, and reproducible ML workflows.

 · Exposure to MLOps, deep learning, or generative AI where relevant to an applied business problem.

· Credentials or practical knowledge in operations, supply chain, Lean, or CPIM are an asset.

The compensation for this position is between $91,300 and $110,000 annually, based on experience and qualifications.
