Process Engineering

• Support characterization, optimization, and control of photolithography and etch manufacturing processes.
• Monitor process performance and analyze data to identify trends, opportunities, and process variation.
• Utilize Statistical Process Control (SPC) methods and process capability metrics (Cp/Cpk) to maintain stable processes.
• Assist with the design, execution, and analysis of Design of Experiments (DOE) activities.
• Investigate process excursions, defects, and yield losses using structured problem-solving methodologies.
• Perform root cause analysis and implement corrective and preventive actions (CAPA).
• Support process validation, qualification, and change management activities.
• Conduct risk assessments utilizing PFMEA, control plans, and related methodologies.
• Develop and maintain process documentation, operating procedures, specifications, and work instructions.
• Create and maintain process dashboards, KPIs, and manufacturing performance reports.

Manufacturing & Continuous Improvement

• Participate in Lean Manufacturing and Six Sigma initiatives focused on efficiency and waste reduction.
• Support Kaizen events and continuous improvement projects.
• Identify opportunities to improve process capability, cycle time, throughput, and equipment utilization.
• Contribute to cost reduction and productivity improvement efforts.
• Assist with capacity planning and manufacturing optimization activities.
• Implement error-proofing (Poka-Yoke) solutions to enhance quality and reduce defects.
• Develop and sustain standard work practices that improve operational consistency.

Quality & Compliance

• Support compliance with quality management systems and applicable industry standards.
• Participate in change control activities, process audits, and documentation reviews.
• Assist in managing nonconformance investigations and corrective action implementation.
• Support calibration programs and Measurement System Analysis (MSA/GR&R) activities.
• Ensure manufacturing processes comply with internal procedures and regulatory requirements.

Project & Cross-Functional Support

• Lead or support small-to-medium scope engineering projects.
• Collaborate with Manufacturing, Equipment Engineering, Quality, Facilities, Supply Chain, and R&D teams to resolve technical challenges.
• Work with equipment vendors, suppliers, and contractors on process-related improvements.
• Support capital equipment installations, qualifications, process transfers, and technology transfers.
• Prepare technical reports, presentations, and engineering recommendations for stakeholders.

Preferred Qualifications & Experience:

• Experience supporting semiconductor wafer fabrication, photolithography, etch, thin film, plating, metrology, MEMS, advanced packaging, assembly, test, or other precision manufacturing processes.
• Experience sustaining and improving manufacturing processes to achieve safety, quality, yield, throughput, and cost objectives.
• Experience supporting process transfers, technology transfers, new product introductions (NPI), or manufacturing scale-up activities.
• Experience implementing CAPA and continuous improvement initiatives.
• Experience working within documented quality systems and regulated manufacturing environments.
• Familiarity with ISO 9001, IATF 16949, AS9100, ISO 13485, or similar quality management systems.
• Six Sigma Green Belt certification or equivalent continuous improvement training.
