About the Role

As a Maddox OEM Supply Planner, you will report to the Supplier Relations Manager under the direction of the OEM Purchasing Team Lead in a fast-paced procurement environment.

You will also assist the OEM Purchasing Team Lead and Analyst with purchasing, planning, supplier performance, and reporting projects as needed.

Daily tasks include reviewing weekly sales trends, calculating replenishment orders, and directing OEM Purchase Order Coordinators on what, how many, and from whom to order.
