About The Position

The Senior Production Planner will own and maintain the master production schedule for a production facility. The position holder serves as the principal point of accountability for the production plan and is responsible for establishing the schedule, administering the change control process, and determining the appropriate response, within agreed parameters, when demand, material availability, or capacity conditions change. The role occupies the intersection of demand forecasting, materials management, and manufacturing execution. Operations executes against the schedule issued by this position, purchasing procures to it, and the commercial organization derives customer commitments from it. Where the plan and operating reality diverge, this position leads the resolution in coordination with operations, purchasing, and commercial stakeholders, and escalates decisions that fall outside [defined thresholds]. This is a senior individual-contributor appointment carrying meaningful decision-making responsibility and significant cross-functional visibility.
