Sr Quality Engineer

A Day in Your Life at MKS:

As the Senior Quality Engineer at the MKS ESI Klamath Falls manufacturing site, you will serve as the site’s primary quality resource and provide hands-on support for the production of precision consumable MLCC carrier plates. Working closely with Operations, Engineering, Supply Chain, and customers, you will own day-to-day product and process quality, sustain the ISO 9001:2015 quality management system, resolve internal and external quality issues, and lead practical improvements that protect delivery, cost, and customer performance. This role requires an experienced manufacturing quality professional who can operate independently, balance production urgency with disciplined quality controls, and build scalable processes appropriate for a small, high-mix/mid-to-high-volume operation.

You Will Make an Impact By:

Production Quality & Process Control:

• Provide daily floor support for machining, finishing, cleaning, inspection, packaging, and release of consumable carrier plates.
• Develop and maintain control plans, inspection instructions, acceptance criteria, sampling plans, and reaction plans for critical product and process characteristics.
• Interpret customer drawings, specifications, tolerances, and workmanship requirements; ensure requirements are translated into effective production and inspection controls.
• Apply SPC, capability analysis, first-pass yield, defect pareto, and trend analysis to prevent escapes and reduce variation, scrap, and rework.
• Establish and sustain measurement methods, gage calibration, measurement system analysis, and inspection equipment controls appropriate to dimensional and surface-quality requirements.
• Support new product introduction and process changes through risk assessment, process qualification, first article approval, and production readiness reviews.
• Maintain product identification, traceability, inspection status, record retention, and final release controls.

Nonconformance, Corrective Action & Customer Quality:

• Own the control and disposition of nonconforming material, including containment, segregation, material review documentation, and verification of rework or repair.
• Lead structured root cause investigations and corrective actions using 8D, 5-Why, fishbone, and risk-based problem-solving methods; verify effectiveness before closure.
• Coordinate responses to customer complaints, returns, corrective action requests, and quality inquiries with timely containment and fact-based communication.
• Analyze internal defects, customer escapes, and warranty or return data to identify systemic risks and prioritize prevention.

Quality Management System & Compliance:

• Serve as the site focal point for the ISO 9001:2015 quality management system, ensuring required processes, procedures, records, and performance reviews remain effective and audit-ready.
• Plan and conduct internal audits; coordinate external certification and customer audits; manage findings, corrective actions, and on-time closure.
• Maintain document and change control, training competence records, calibration controls, quality records, and risk-based operational controls.
• Prepare quality inputs for management review, including objectives, KPI trends, audit results, customer performance, nonconformities, risks, and improvement actions.

Supplier Quality & Incoming Material:

• Define incoming inspection and supplier controls based on material risk, historical performance, and process capability.
• Investigate supplier-related nonconformances, issue supplier corrective action requests, and verify corrective-action effectiveness.
• Partner with Supply Chain and suppliers on qualification, performance monitoring, change notification, and improvement of critical materials and outsourced processes.

Quality Metrics & Continuous Improvement:

• Own a practical site quality dashboard covering customer complaints, defects, scrap, rework, first-pass yield, process capability, supplier performance, audit actions, and corrective-action closure.
• Facilitate cross-functional improvement projects using Lean, Six Sigma, mistake-proofing, standard work, and risk-reduction methods.
• Train and coach production personnel on inspection, defect recognition, nonconformance control, problem solving, and adherence to quality procedures.
• Escalate significant product, process, compliance, or customer risks and drive clear ownership and closure of corrective actions.

• Strong working knowledge of ISO 9001:2015, internal auditing, document control, corrective action, risk-based thinking, and management review.
• Proficiency in control plans, inspection planning, SPC, process capability, sampling, measurement system analysis, calibration, and basic statistical analysis.
• Experience leading root cause analysis and corrective action for internal defects, customer complaints, and supplier nonconformances.
• Ability to interpret engineering drawings, specifications, dimensional tolerances, and customer-specific quality requirements.
• Proficiency with common metrology tools and quality data systems; experience with ERP, Minitab or equivalent statistical software, and electronic QMS tools is preferred.
• Strong written and verbal communication skills, sound judgment, and the ability to work directly with operators, leaders, suppliers, auditors, and global customers.
