In this role you will:

• Drive plant quality performance through effective process control, root-cause analysis, corrective/preventive actions, and continuous improvement initiatives across manufacturing operations.

• Lead factory quality issue resolution byutilizingstructured problem-solving methodologies (e.g., 8D, RCA, CAPA) to address product and process nonconformance.

• Support daily manufacturing quality activities bymonitoringcritical process and product parameters, ensuring process stability and compliance with quality standards.

• Monitor and improve key factory quality metrics including Yield, Scrap, DPPM,CCPK,SPC, andCpkto achieve operational and businessobjectives.

• Manage non-conforming materials and products, coordinate containment activities, prevent recurrence, and ensuretimelydisposition with production and engineering teams.

• Partner closely with Production, Process Engineering, Manufacturing Engineering, Supply Chain, and Operations teams to drive sustainable quality and process improvements.

• Apply statistical analysis and SPC methodologies to support process capability improvement, control plan effectiveness, and manufacturing risk reduction.

• Conduct process audits, quality reviews, and production line assessments to ensure compliance with internal procedures, customer requirements, and regulatory standards.

• Participate in qualification and validation activities for new products, materials, equipment, tooling, and process changes to ensure manufacturing readiness and quality performance.

• Lead thechangemanagement activities including risk assessment, documentation updates, process verification, andimplementationeffectiveness tracking.

• Prepare andmaintainquality documentation, performance tracking systems, quality reports, CAPA records, and continuousimprovementproject documentation.

• Collaborate with global quality organizations and cross-functional manufacturing teams to standardize best practices and enhance operational excellence across sites.

• Demonstrate strong execution, teamwork, learning agility, communication, and leadership behaviors aligned with Entegris PACE values.

Traits we believe make a strong candidate:

• Bachelor’s degree or above in Chemical, Mechanical, Electrical/Electronic Engineering, or other related technical disciplines.

• Experience in quality, manufacturing, process, equipment, or materials engineering within semiconductor or high-tech manufacturing industries.

• Solid experience supporting plant/manufacturing quality operations, including process control, line quality improvement, excursion management, and continuous improvement activities.

• Hands-on experience with quality methodologies and tools such as FMEA, SPC, MSA, Control Plan, 8D, CAPA, DOE, process mapping, and statistical data analysis.

• Strong problem-solving capability with the ability to perform root-cause analysis and drive effective corrective and preventive actions in manufacturing environments.

• Experience working cross-functionally with Production, Process Engineering, Manufacturing Engineering, Supply Chain, and Operations teams to resolve quality and process issues.

• Familiarwith manufacturing KPI management including Yield,FPY, Scrap, DPPM,CCPK,Cpk, and process capability improvement.

• Knowledge of quality systems, change management, audit processes, risk assessment, and qualification/validation activities.

• Self-motivated, results-oriented, and capable of managing multiple priorities in a fast-paced manufacturingenvironment.

• Strong communication, teamwork, planning, and execution skills with the ability to influence and drive operational improvements.

• Ability toidentifyopportunities and implement sustainable quality and process improvements that positivelyimpactmanufacturing performance and customer satisfaction.

• Excellent written and verbal communication skills in both English and Mandarin.

Your success will be measured by:

• Achievement of key plant quality and manufacturing performance metrics including Yield, FPY, Scrap, DPPM,CCPK,Cpk, excursion reduction, and CAPA effectiveness.

• Effectiveness in driving process control, root-cause analysis, corrective/preventive actions, and continuous improvement initiatives across manufacturing operations.

• Ability to support stable production quality, reduce process variation, and improve overall factory operational performance.

• Successful collaboration with cross-functional teams including Production, Process Engineering, Manufacturing Engineering, Supply Chain, Operations, and Global Quality organizations.

• Timely resolution and containment of manufacturing quality issues while preventing recurrence and minimizing production impact.

• Contribution to quality system compliance, audit readiness, qualification activities, and implementation of sustainable process improvements.

• Demonstration of strong ownership, execution, teamwork, communication, and problem-solving capabilities in support of plant and businessobjectives.

• Alignment with Entegris PACE values emphasizing People and Teamwork, Accountability, Creativity and Innovation, and dedication to Excellence.
