The ML/AI Engineer designs, builds, and operationalizes machine learning models and AI-powered solutions that drive measurable business value across mSupply’s distribution operations. Working within the enterprise data platform (Microsoft Fabric, dbt, Power BI), this role partners with Data Scientists, Data Engineers, and Business Product Owners to turn analytical models into reliable, scalable production systems. You will bridge the gap between data science experimentation and production-grade AI. Your models will directly influence inventory positioning, demand forecasting, pricing strategy, and customer segmentation across a multi-location distribution network. If you want to build ML systems that run at scale in a real operational environment, not just prototypes that never ship, this is the role.
