About The Position

The SIOP (Supply, Inventory, Operations & Planning) Manager leads McFarlane Aviation's planning, purchasing, inventory, and distribution functions, with oversight of the Purchasing team and the Distribution Supervisor. This role builds the systems and processes that turn customer demand, material requirements, supplier capability, and production capacity into an executable plan — with a strong focus on our ERP/MRP system and improving on-time delivery, fill rate, schedule attainment, and inventory performance. We’re looking for someone who can pull planning, purchasing, inventory, and distribution together into one connected system, partners closely with Operations, and is just as comfortable running the planning cadence from the ERP screen as walking the warehouse floor with the Distribution team.

7+ years of progressive experience in supply chain, materials, planning, or manufacturing operations, including leadership experience
Demonstrated experience building, improving, or leading an ERP/MRP-driven planning system in a manufacturing environment
Strong working knowledge of MRP, material and production planning, capacity planning, inventory management, purchasing, and supplier management
Demonstrated ability to translate demand into material, capacity, and production requirements
Experience improving operational measures such as OTD, fill rate, schedule attainment, inventory accuracy, shortages, or supplier performance
Strong understanding of ERP master data and how planning parameters affect purchasing, inventory, capacity, and production execution
Experience leading Buyers, Buyer/Planners, Distribution or Warehouse Supervisors, Material Planners, or similar roles
