• Partner with tooling and maintenance teams to minimize downtime and improve changeover efficiency (SMED).
• Drive scrap reduction and die performance optimization.
• Oversee CNC wire bending/forming machines and related automation.
• Ensure program accuracy, tooling selection, bend sequence optimization, and repeatability.
• Monitor wire feed systems, straighteners, and cut-to-length performance.
• Collaborate with quality to maintain tight tolerance control on formed components.
• Partner with Master Planner/Scheduler to align production output with demand and capacity planning.
• Drive throughput improvements across laser, stamping, forming, and secondary operations.
• Accountable for production quality, first-pass yield, and corrective action implementation.
• Maintain MRO budget and ensure cost-effective procurement of tooling, consumables, and spare parts.
• Lead Lean Manufacturing initiatives including Kaizen events, 5S, visual management, and waste elimination.
• Monitor KPIs including OEE, scrap %, labor efficiency, and on-time delivery.

• Coordinate with Supply Chain to manage raw material levels (sheet steel, coil stock, wire rod).
• Ensure accurate inventory transactions within ERP/MRP systems.
• Oversee cycle counts, annual physical inventory, and WIP accuracy.
• Optimize material flow from receiving through fabrication to shipping.
• Work closely with Maintenance to maximize equipment uptime across lasers, presses, and wire formers.
• Ensure adherence to preventative and predictive maintenance schedules.
• Support root cause analysis on equipment failures.
• Drive continuous improvement in machine reliability and asset longevity.
• Maintain plant organization and cleanliness aligned with 5S methodology.
• Implement continuous improvement strategies to improve workflow and reduce bottlenecks.
• Support layout optimization initiatives for fabrication cells and material staging.
• Maintain appropriate staffing levels aligned with production demands.
• Enforce performance management standards.
• Develop team members in laser programming & operation, press setup, wire forming, and Lean methodologies.
• Foster cross-training initiatives to increase workforce flexibility.
• Lead by example in accountability, discipline, and performance expectations.
• Perform other duties as assigned by manager(s).

• Bachelor’s degree in Engineering, Manufacturing, Operations Management, or equivalent experience.
