• Troubleshoot complex manufacturing issues and lead cross-functional problem-solving efforts.
• Support and improve manufacturing processes involving fine wire processing; cable extrusion and jacketing; tubing extrusion; braiding; taping and serving operations; and cabling and shield application.
• Drive Lean Manufacturing and continuous improvement initiatives throughout the facility.

• Collaborate with machine development teams to define requirements for new manufacturing equipment.
• Provide technical input for machine control systems, automation strategies, PLC integration, and production monitoring systems.
• Participate in equipment specification, design reviews, factory acceptance testing, installation, and commissioning activities.
• Support development of next-generation manufacturing technologies and production capabilities.

• Develop and maintain process documentation, work instructions, process specifications, and validation records.
• Partner with Quality Engineering to support PFMEA development, control plans, corrective actions, and process validation activities.
• Ensure processes comply with internal quality standards and customer requirements.

• Work closely with Product Development Engineering to evaluate manufacturability and improve product designs.
• Support Manufacturing and Operations teams with technical expertise and training.
• Mentor junior engineers and manufacturing personnel on best practices, problem solving, and process control.

• 7+ years of process engineering or manufacturing engineering experience in a production environment.
• Experience in one or more of the following industries:
• wire and cable; RF/microwave components
• fiber optics
• electrical connectors
• aerospace and defense manufacturing
• Experience leading manufacturing process development and product launch activities.
• Working knowledge of PLC-controlled equipment, automation systems, motor drives, and industrial controls.

• Direct experience with small-diameter, high-performance cable manufacturing.
• Extensive extrusion experience involving FEP, PFA, PTFE, ETFE, or other high-temperature fluoropolymers.
• Primary insulation and jacketing extrusion expertise.
• Microwave cable serving and shielding experience.
• Fine wire processing experience.
• Design of Experiments (DOE) and statistical analysis experience.
• Lean Manufacturing or Six Sigma certification.
• Experience specifying, commissioning, and improving automated manufacturing equipment.
• Knowledge of data acquisition, machine vision, SPC systems, and advanced process controls.
• Experience in ISO 9001, AS9100, or medical device quality environments.
