You will evaluate existing and new manufacturing requirements; propose new methods, measurement strategies, and process controls to maximize manufacturing efficiency, improve yield, reduce defects, and ensure product quality.

The Metrology Engineer will drive the following key business processes in the silicon carbide growth and fabrication factory:

• Optimize, troubleshoot, and support metrology tools and inspection systems used in manufacturing operations.
• Perform measurement system analysis (MSA) studies to ensure accuracy, repeatability, and reproducibility of measurement methods and equipment.
• Develop, maintain, and improve Statistical Process Control (SPC) systems and monitoring strategies for critical process parameters.
• Conduct data analysis using Minitab and other analytical tools to identify trends, variation sources, process capability, and improvement opportunities.
• Lead root cause investigations and corrective action activities for quality issues, defect escapes, yield loss, and process excursions.
• Drive defect screening improvement initiatives focused on defect reduction, containment effectiveness, and yield enhancement.
• Develop and maintain inspection criteria, quality screening methods, and process control strategies.
• Support Failure Mode and Effects Analysis (FMEA) and Control Plan development and maintenance for manufacturing processes.
• Perform risk assessments and support implementation of preventive actions to reduce process and product quality risks.
• Collaborate with manufacturing teams to improve process stability, measurement reliability, product quality, and operational efficiency.
• Generate reports, dashboards, and statistical analyses to support management decision-making and continuous improvement initiatives.
• Support internal, customer, and third-party audits, including compliance with IATF requirements and quality management system standards.
• Promote Lean Manufacturing principles including 5S, Kanban systems, standard work, and continuous improvement practices.
• Assist with qualification activities for new equipment, measurement methods, process changes, and manufacturing improvements.
• Train operators, technicians, and engineers on quality tools, SPC methodologies, inspection techniques, and metrology best practices.
• Participate in cross-functional teams to improve manufacturing performance, cycle time, capacity utilization, and product quality.
• Other duties as needed or assigned.

The successful candidate will possess:

• B.S. degree in Engineering (Mechanical Engineering, Industrial Engineering, Manufacturing Engineering, Chemical Engineering, Electrical Engineering, or related discipline).
• 3-7 years of engineering experience in manufacturing, quality, metrology, process engineering, or semiconductor operations preferred.
• Strong understanding of Statistical Process Control (SPC), process capability analysis, and statistical problem-solving techniques.
• Experience conducting Measurement System Analysis (MSA), Gauge R&R studies, and measurement system qualification activities.
• Working knowledge of FMEA, Control Plans, risk analysis methodologies, and corrective/preventive action systems.
• Experience with Minitab for statistical analysis, data visualization, and process improvement projects.
• Familiarity with IATF 16949 requirements, audit preparation, and quality management systems.
• Experience working with manufacturing quality systems, defect screening methods, and yield improvement programs.
• Knowledge of root cause analysis tools including 8D, Fishbone, 5 Why, and other structured problem-solving methodologies.
• Understanding of Lean Manufacturing principles including 5S, Kanban, waste reduction, and continuous improvement practices.
• Strong analytical skills with the ability to interpret large data sets and communicate actionable recommendations.
• Proficiency with Microsoft Office applications, including Excel for data analysis and reporting.
• Excellent communication and presentation skills with the ability to work effectively across cross-functional teams and organizational levels.
• Highly organized, self-motivated, and capable of managing multiple priorities in a fast-paced manufacturing environment.
