Summary

The Process Engineering Technician IV is a senior level engineering technician on the process engineering team, serving as a subject matter expert and process owner for advanced manufacturing processes supporting thin-film-based pigments production. The role requires a high degree of self-direction and independent judgment, operating with minimal daily oversight to lead process control, complex troubleshooting, and continuous improvement efforts across roll-coating platforms and post-process unit operations, while providing technical mentorship to less experienced technicians. Advanced analytical skills and proficiency with MS Excel, production data systems, and statistical methods are essential.

This is a 24x7 production support role requiring shift flexibility. 12-hour shift assignments. As the senior on-shift technical resource, this role is typically the primary escalation point for off-shift process and quality issues.

Process Troubleshooting

• Act as the primary escalation point for complex, cross-shift process issues; lead root-cause investigations and implement corrective actions with minimal engineering oversight.

Metrology & Data Analysis

• Develop and improve data analysis systems and tools; independently design and execute studies and experiments; produce comprehensive technical reports and present findings to engineering and leadership.

Production Documentation

• Author and own work instructions, standard operating procedures, and Product/Process Change Notices (PCNs); serve as process owner of record for one or more manufacturing processes.

Quality Management

• Provide final disposition on complex or ambiguous non-conforming material reports (NCMRs); drive root-cause corrective and preventive actions; actively lead QMS, EHS, and Continuous Improvement initiatives.

Cross-Functional Collaboration

• Lead or facilitate cross-functional projects and problem-solving teams; serve as a recognized technical resource for engineering, quality, and operations organizations.

Training & Development

• Train, mentor, and provide technical oversight to Process Engineering Technicians I-III; own and continuously improve training content and standard work documentation.

Engineering Project Support

• Independently lead or manage engineering projects including NPI, continuous improvement, corrective and preventive actions, PFMEAs, HAZOP studies, and quality tools, with reduced engineering oversight.

Safety & Compliance
