A well-established window and door manufacturer is seeking an experienced Plant Manager to lead its Riverside, California operation.

This is a hands-on plant leadership role with broad responsibility across manufacturing, production planning, warehouse and shipping operations, inventory, purchasing, maintenance, safety, quality, staffing, and continuous improvement.

The right candidate will inherit an operation with a capable workforce and meaningful opportunity to improve performance. We are looking for someone who can establish operating discipline, strengthen accountability, improve production flow, reduce backorders, and build a more consistent Lean operating culture.

The Opportunity

The Plant Manager will lead a non-union, single-shift manufacturing operation with approximately 110 employees. The facility manufactures vinyl window and door products and currently produces approximately 250–400 units per day.

Reporting directly to senior leadership, this individual will have the visibility and authority to influence the operation across multiple functions and lead meaningful change.

Key Responsibilities

• Lead day-to-day plant operations while delivering against safety, quality, delivery, cost, and productivity objectives.

• Improve inventory accuracy, material availability, and coordination between purchasing, manufacturing, warehouse, and shipping.
• Ensure preventive and predictive maintenance programs support equipment reliability and reduced downtime.
• Maintain strong safety and quality standards throughout the operation.
• Recruit, train, coach, and develop plant leaders and employees.
• Support budget performance, margin improvement, cost reduction, and effective asset utilization.
• Promote a culture of continuous improvement, urgency, ownership, and respect.

What We Are Looking For

• At least five years of progressive manufacturing leadership experience
• Experience leading a manufacturing plant or a substantial portion of plant operations
• Demonstrated success improving safety, quality, delivery, productivity, staffing, or cost performance
• Strong knowledge of Lean manufacturing and KPI-based operating management
• Experience managing production, warehouse, shipping, inventory, maintenance, or related supply-chain functions
• Strong analytical, problem-solving, communication, and people-leadership skills
• Bachelor’s degree in business, industrial engineering, engineering, operations, or a related field preferred
