Senior Engineer, Quality Assurance Engineering

The Role: 

Entegris is seeking a highly motivated Chemical Process Engineer who thrives in a fast-paced environment where safety, quality and continuous improvement are paramount. You will be a key player on a dynamic, skilled team whose objective is to sustain and continuously improve specialty chemical processes used in semiconductor manufacturing. Our specialty chemicals enable our customers to build high performance semiconductor products. 

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 by utilizing structured problem-solving methodologies (e.g., 8D, RCA, CAPA) to address product and process nonconformance. 

• Support daily manufacturing quality activities by monitoring critical 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, and Cpk to achieve operational and business objectives. 

• Manage non-conforming materials and products, coordinate containment activities, prevent recurrence, and ensure timely disposition 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 the change management activities including risk assessment, documentation updates, process verification, and implementation effectiveness tracking. 

• Prepare and maintain quality documentation, performance tracking systems, quality reports, CAPA records, and continuous improvement project 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. 

• Familiar with 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 manufacturing environment. 

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

• Ability to identify opportunities and implement sustainable quality and process improvements that positively impact manufacturing 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 business objectives. 

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