Job Summary: Reporting to the Plant Manager, the Manufacturing Process Engineer is responsible for developing, optimizing, and sustaining manufacturing processes to improve efficiency, quality, and cost performance. This role serves as the liaison between customer engineering requirements and the production floor, translating customer specifications into manufacturable processes, and supporting accurate cost estimation for quoting. The Manufacturing Process Engineer partners closely with production, maintenance, quality, and engineering teams to troubleshoot issues, reduce waste, improve process capability, and drive continuous improvement across machine operations and production workflows.

Essential Duties and Responsibilities:

Process Development & Optimization

• Design, implement, and improve manufacturing processes to increase efficiency, throughput, and yield

• Analyze production workflows to eliminate waste and improve cycle times

• Develop and maintain standard work instructions, PFMEA (Process Failure Modes & Effects Analysis), and control plans

• Support new product introductions (NPI) with scalable, repeatable, and well-controlled processes

• Conduct Design of Experiments (DOE) and process capability studies to optimize process performance and stability

Production Support & Troubleshooting

• Provide hands-on support to production teams to resolve process and equipment issues

• Perform root cause analysis and implement corrective and preventive actions (CAPA)

• Monitor process performance and improve yield, scrap, and efficiency

• Collaborate with maintenance to resolve equipment-related issues impacting production

Machine & Equipment Optimization

• Evaluate and improve machine performance, reliability, and capability

• Support equipment selection, installation, validation, and commissioning

• Develop and maintain process parameters to ensure consistent operation within defined limits

• Drive improvements in Overall Equipment Effectiveness (OEE)

Continuous Improvement

• Lead Lean Manufacturing and Six Sigma initiatives to improve productivity and reduce costs

• Facilitate Kaizen events and structured improvement projects

• Identify and implement automation opportunities where applicable

• Track and report improvements in key metrics

Quality & Compliance

• Partner with quality teams to ensure processes meet product specifications and compliance standards

• Develop and implement process controls, including SPC (Statistical Process Control), PFMEA, and control plans

• Perform Measurement System Analysis (MSA), including Gage R&R studies, to ensure accuracy and reliability of measurement systems

• Conduct process capability analysis (Cp, Cpk) and drive continuous quality improvement

• Support internal and external audits and maintain compliance with quality systems (e.g., ISO)

• Drive defect reduction and sustainable corrective actions

Safety & Ergonomics

• Ensure manufacturing processes incorporate safety and ergonomic best practices to minimize risk of injury and improve operator efficiency

• Identify and mitigate process-related safety risks, including ergonomics, machine guarding, and material handling

• Partner with EHS and operations teams to support safe work environments and continuous safety improvement initiatives

• Support implementation of safety standards, procedures, and training related to process changes.

Cross-Functional Collaboration

• Work closely with production, quality, maintenance, supply chain, and engineering teams

• Act as the technical bridge between customer requirements and manufacturing execution
