Lead Engineer, Manufacturing

Entegris is =seeking a Lead Engineer, Manufacturing to join our CMP Polishing Pads Manufacturing Engineering team. This position will be based in our Aurora, IL facility. 

As a new hire in this role, you will be responsible for the back-end manufacturing processes within the CMP Polishing Pads Business Unit at our Aurora 500C facility, with primary ownership of the grooving process (eCAM 4-axis CNC and Multicam 4-axis CNC groovers) and the Multicam milling operations. Reporting to the Engineering Manager, you will drive safety, quality, and productivity improvements, support New Product Introductions (NPIs) and Product Change Notifications (PCNs), and lead continuous improvement, cost-saving, and equipment-qualification initiatives across grooving, milling, and cleaning-room operations. 

WHAT YOU'LL DO

Manufacturing Process Support (45%) 

• Provide dedicated engineering leadership for the grooving process, including eCAM concentric and XY grooving, Multicam plunge grooving, and Multicam milling operations. 

• Serve as the site technical expert for eCAM 5-axis and Multicam 4-axis machines; develop and deliver training and certification for Operation Associates and Engineering Technicians. 

• Drive safety, quality, and productivity improvements across back-end manufacturing (grooving, milling, and cleaning-room operations). 

• Lead root-cause investigations of out-of-control conditions; troubleshoot equipment and processes and implement permanent corrective actions. 

• Develop, optimize, and maintain CNC programs (G-code / M-code), CAM post-processors, and recipe libraries for grooving and milling operations. 

• Provide hands-on technical support during machine breakdowns; coordinate external repair resources as needed. 

• Improve the preventative and predictive maintenance program for grooving and milling equipment to maximize uptime and OEE. 

• Own the Management of Change (MOC/EtQ) process for grooving and milling process changes. 

NPI / PCN Engineering Support (25%) 

• Ensure new product process flows are Designed for Manufacturing (DFM); review all NPI/PCN activities requiring grooving and milling operations. 

• Manage product scale-ups from Low Volume Manufacturing (LVM) to High Volume Manufacturing (HVM); coordinate process transfers with Product Development. 

• Partner with Product Development for surfacing (HAAS) and grooving (eCAM) programs — from process development through production readiness. 

• Design and execute DOE trials to validate new grooving and milling configurations, blade and tooling sets. 

• Lead MOC documentation and qualification plans for new product introductions and process changes. 

Productivity, Continuous Improvement & Cost-Saving Projects (20%) 

• Identify and implement safety, quality, productivity, and cost improvements across grooving and milling operations. 

• Act as the dedicated engineering resource to unblock stalled CI and cost-saving initiatives. 

• Apply statistical tools (SPC/SQC, DOE, Six Sigma) to reduce process variation and improve yield.
