Leadership & Continuous Improvement

• Own the KPIs and performance metrics for the Purchasing/Planning and Distribution functions, aligned with company objectives

• Partner closely with Operations, Sales, Engineering, Quality, Finance, and Customer Service


• Develop standardized processes and departmental SOPs that support scalable growth and regulatory requirements


• Develop the planning, purchasing, and distribution organization to operate proactively through systems and standard processes rather than reactive expediting

• Demonstrated experience building, improving, or leading an ERP/MRP-driven planning system in a manufacturing environment

Preferred

• Experience with S&OP/SIOP or other integrated demand and supply planning processes preferred

• Can our ERP/MRP system provide reliable signals that our team can execute against?

Ultimately, success will be demonstrated through measurable improvement in customer OTD, fill rate, schedule attainment, material availability, supplier performance, inventory accuracy, distribution performance, and planning effectiveness, while reducing reliance on expediting and manual intervention.
