Senior Quality Engineer

At Entegris, we are looking for a Senior Quality Engineer to join our Advanced Purity Solutions Quality organization at our Chaska, Minnesota manufacturing facility.

The Chaska facility manufactures high-purity fluid handling products and components using a diverse range of manufacturing technologies, including injection molding, extrusion, machining, blow molding, rotational molding, compression molding, assembly, and related processes.

This position will serve as a key Quality partner to Manufacturing, Engineering, Operations, and other cross-functional teams.

The Senior Quality Engineer will provide hands-on quality engineering support for assigned products and manufacturing processes, lead structured problem solving, manage product and process risk, drive corrective actions and continuous improvement, and help strengthen the site's overall quality systems and performance.

This is an excellent opportunity for an experienced Quality Engineer who enjoys being close to manufacturing, solving complex problems, working across functions, and moving an organization from reactive problem solving toward proactive quality improvement.

In this role, you will

• Provide day-to-day Quality Engineering support for assigned Chaska products, manufacturing areas, and value streams.

• Lead and support investigations of internal and customer quality issues, including containment, root-cause analysis, corrective action, effectiveness verification, and closure.

• Coordinate and support Quality Notifications (QNs), material review activities, product disposition, and risk assessments. This will require working cross-functionally with Operations, Customer Service, Materials, Tooling, and other functions as appropriate.

• Partner directly with Manufacturing and Engineering to identify recurring defects and process variation and implement sustainable corrective and preventive actions.

• Apply structured problem-solving and statistical methods to manufacturing and quality issues, using tools such as FMEA, SPC, capability analysis, Pareto analysis, MSA/Gage R&R, process mapping, and 8D/root-cause methodologies.

• Support customer complaint investigations and help develop technically sound, timely responses and corrective-action packages.

• Participate in and support customer, internal, and quality-system audits.

• Support change management activities, including risk assessment, manufacturing change reviews, validation and qualification activities, and quality documentation.

• Develop, review, and maintain quality-related documentation such as inspection methods, control plans, risk assessments, specifications, and other process-control documentation.

• Support new product introduction and product/process changes through FMEAs, control plans, measurement strategies, validation/qualification activities, and data analysis.

• Use manufacturing and quality data to identify adverse trends and proactively drive improvements in product quality, process capability, defect reduction, and customer performance.

• Work with Operations and Engineering to strengthen process controls and prevent defects rather than relying exclusively on inspection or containment.

• Participate in continuous-improvement activities and cross-functional projects that improve quality, delivery, cost, and manufacturing effectiveness.

• Serve as a technical Quality resource for engineers, technicians, inspectors, manufacturing leaders, and operators.

• Mentor less-experienced engineers and help build structured problem-solving capability across the organization.

Traits we believe make a strong candidate

• Demonstrated ability to independently lead complex quality investigations from initial containment through sustainable corrective action.

• Strong analytical and structured problem-solving skills.

• Comfortable working directly on the manufacturing floor and collaborating with operators, technicians, engineers, and leadership.

• Ability to balance urgent production/customer needs with longer-term systemic improvements.

• Strong technical judgment and an ability to make risk-based decisions using data.

• Effective written and verbal communication skills, including the ability to explain technical quality issues to different audiences.

• Strong cross-functional collaboration skills and the ability to influence without relying solely on formal authority.

• A proactive mindset with an interest in preventing defects and improving processes rather than simply responding to failures.

• Ability to manage several priorities simultaneously in a fast-paced manufacturing environment.

Minimum qualifications

• Bachelor's degree in Engineering, Quality, Manufacturing, Materials Science, or a related technical discipline.

• Approximately 5 or more years of relevant Quality Engineering or closely related manufacturing engineering experience.

• Experience in a manufacturing environment.

• Demonstrated experience with root-cause analysis, corrective action, risk assessment, and structured problem solving.

• Experience applying core quality tools such as FMEA, SPC, MSA/Gage R&R, control plans, process capability, and statistical analysis.

• Experience working with cross-functional manufacturing and engineering teams.

• Proficiency with Microsoft Office applications.
