Role Summary
Grayson Thermal Systems manufactures advanced Thermal Management Systems used for heating and cooling Electric, Hydrogen, and Hydrogen Fuel Cell buses and trucks. As a key supplier to global OEMs, we operate in a fast‑paced and dynamic manufacturing environment.
Reporting to the Materials Team Leader, you will provide comprehensive support across all material planning activities. The role requires accurate interpretation of manufacturing demand using MRP within our ERP system. You will be responsible for scheduling orders—either weekly or monthly—via MRP or spot purchases, ensuring suppliers are provided with accurate lead times and maintaining continuity of supply.
A core focus of the role is ensuring components are delivered on time and that any risks to supply are identified early and resolved promptly to prevent production line stoppages. You will manage a designated supplier base, maintaining consistent material flow and escalating issues where necessary. In cases of non‑delivery, you will work with the Materials Team Leader to implement corrective actions or coach suppliers to improve performance. Ensuring data accuracy within the ERP system is essential to avoid administrative discrepancies.
