• 5+ years'' experience in manufacturing engineering, process engineering, industrial engineering, or production operations within a precision manufacturing environment.
• Demonstrated experience reducing manufacturing cost through cycle time reduction, yield improvement, labor efficiency, material utilization, scrap reduction, and routing accuracy.
• Practical knowledge of Lean Manufacturing, Six Sigma, SPC, DOE, FMEA/PFMEA, process capability, root cause analysis, and corrective action methods.
• Experience developing and maintaining manufacturing documentation including routers, travelers, work instructions, BOMs, process flows, standard labor assumptions, and control plans.
• Working knowledge of automation, robotics, machine integration, data acquisition, and manufacturing systems used to improve process repeatability and throughput.
• Proficiency with Microsoft Office tools and data analysis/reporting platforms; ability to interpret ERP/MRP, production, quality, and cost data to drive action.

Skills

• Experience supporting optical, crystal, ceramic, sapphire, YVO4, or other precision component manufacturing processes.
• Hands-on experience implementing automation, robotics, vision systems, AI-enabled analytics, or machine learning tools in a manufacturing environment.
• Lean Six Sigma Green Belt/Black Belt, SME, ASQ, or equivalent continuous improvement certification.
• Experience building cost models, capacity models, labor standards, OEE/throughput dashboards, or variance reduction scorecards.
• Strong cross-functional leadership skills with ability to influence Operations, Quality, Planning, Engineering, Supply Chain, and Finance without direct authority.
• Excellent problem-solving, communication, organization, and follow-through skills with a bias toward measurable business results.

Physical Requirements

• Ability to regularly walk throughout manufacturing, assembly, test, coating, polishing, and warehouse areas.
• Ability to stand for extended periods (up to 4-8 hours per day) while supporting production activities, process observations, and troubleshooting efforts.
• Ability to occasionally lift and carry materials, tooling, fixtures, and equipment weighing up to 25 pounds.
