About The Position

The Production Planning and Scheduling Manager oversees the integrated planning function, establishes and leads Sales, Inventory & Operations Planning (SIOP), and develops the processes and ERP data discipline needed to support company growth. The role balances production capacity, inventory, lead times, and operational constraints, translating the master schedule into executable work-center and station-level plans. This position maintains integrated master schedules across multiple customer programs and product platforms that share constrained manufacturing resources. It leads planning process adoption and improvement in a dynamic restart and scale-up environment, making decisions amid imperfect data, evolving requirements, and shifting priorities. The position is based onsite in Riverside, California, with working hours from 8 AM to 5 PM and potential flexibility. There is no immediate team management responsibility, though a team may be managed as the function grows.

Bachelor's degree in Supply Chain, Engineering, Business, or a related field.
At least 6 years of experience in production planning, scheduling, capacity planning, or as a master scheduler, with senior-level proficiency.
Experience in the automotive or aerospace industries.
Deep understanding of manufacturing processes, production planning, inventory management, material availability, capacity planning, customer delivery commitments, and SIOP.
Strong knowledge of ERP systems such as SAP, Oracle, Epicor, or similar platforms, including planning master data and scheduling logic.
Understanding of low-volume, high-mix, and engineered-to-order manufacturing environments with complex capacity constraints and long planning horizons.
Demonstrated ability to manage capacity constraints, production schedules, material requirements, and manufacturing execution workflows.
Ability to incorporate equipment availability, planned downtime, and maintenance constraints into capacity plans in coordination with Facilities and Maintenance.
Strong leadership skills to guide cross-functional adoption of planning processes and resolve barriers with functional leaders.
Ability to operate effectively in a restart and scale-up environment despite imperfect data, evolving requirements, and shifting priorities.

Establish the weekly planning performance review within the Operations management operating system.
Design and implement planning processes, standard work, meeting cadences, responsibilities, escalation rules, and a phased improvement roadmap.
Lead cross-functional adoption of planning processes, resolve barriers with functional leaders, and use performance results to reduce delays, improve flow, and increase schedule reliability.
Maintain direct responsibility for integrated master schedules across multiple customer programs and product platforms sharing constrained resources.
Balance customer, operational, and business priorities, using data to challenge infeasible commitments.
Incorporate equipment availability, planned downtime, and maintenance constraints into production capacity plans in coordination with Facilities and Maintenance.
