• Create and maintain SOPs, standard work documentation, and operational best practices
• Evaluate automation opportunities, capital equipment investments, and ROI-driven manufacturing improvements
• Partner with Production, Quality, Safety, Supply Chain, and Engineering leadership teams to execute operational priorities
• Mentor junior engineers and support the development of a continuous improvement culture throughout the facility

• Bachelor’s degree in Industrial Engineering, Manufacturing Engineering, Mechanical Engineering, or related field
• 5 to 15 years of Industrial Engineering or Manufacturing Engineering experience in a production environment

• Experience with labor studies, line balancing, plant layout development, capacity planning, and KPI management
• Strong analytical and problem-solving skills with the ability to turn operational data into measurable improvements
• Comfortable leading projects and influencing cross-functional teams without direct authority
• ERP and MRP system experience required
• CAD experience preferred
• Six Sigma certification or equivalent continuous improvement training is a plus
