Senior Engineer, Materials Quality Engineering

Entegris • Hillsboro, OR

3d • $85,500 - $125,500

About The Position

Entegris is seeking a Senior Engineer to join its Materials Quality Engineering (Supplier Quality) team. The role supports regional suppliers and U.S. manufacturing operations, assessing and managing quality performance, supplier risk, and capability for polyurethane foams, polymeric materials, and related formulated materials used in CMP polishing pads. It supports the Materials Solutions Division and U.S. manufacturing plants, while collaborating with global teammates. The engineer is expected to work autonomously and use sound engineering judgment to lead supplier development, continuous improvement, and quality systems for critical polyurethane foam suppliers. The role works closely with Commodity Management, Operations, R&D, Customer Quality, Business Units, and Procurement to maintain continuity of supply and resolve internal and customer issues involving quality, variability, and contamination control.

Responsibilities include leading supplier quality activities; improving supplier performance through corrective actions, audits, capability reviews, and process assessments; supporting qualifications, change management, and risk assessments; and investigating foam quality issues using structured root-cause methods. The engineer will develop and maintain specifications, critical-to-quality requirements, COA expectations, test methods, and quality documentation, and collaborate with suppliers on process improvements, capability studies, control plans, sampling strategies, and advanced quality planning. The position also involves monitoring supplier metrics, participating in continuity planning and risk mitigation, and training suppliers on requirements and quality-system standards.

The role requires knowledge of polyurethane foam manufacturing and how process variability affects CMP pad and customer performance. The engineer applies continuous improvement, problem-solving, SPC, and FMEA methods; analyzes complex data to guide decisions; and supports efforts to reduce variation, improve yield and reliability, and strengthen material and product performance. Domestic or international travel of up to 10% is required, as is travel to a local manufacturing plant.

Entegris describes a collaborative, values-driven culture that encourages employee input and aims to support employees’ lives inside and outside work. The position does not offer immigration-related sponsorship.

Requirements

• Bachelor’s degree in Chemical Engineering, Chemistry, Polymer Science or Engineering, Materials Science or Engineering, or a related discipline.

• Working knowledge of polyurethane foam quality systems and controls, including formulation and cure control, physical property testing, contamination control, analytical method capability, SPC systems, PFMEA, and control-plan development.
• Proficiency with statistical analysis software such as Minitab, JMP, SAS, or Camline.
• Strong project management, communication, and interpersonal skills.
• Ability to work independently, lead projects, and collaborate with cross-functional teams.
• Ability to travel up to 10% domestically or internationally and travel to a local manufacturing plant.

Nice To Haves

• Advanced degree.
• Six Sigma Green Belt or Black Belt certification.
• Experience in supplier quality engineering for polyurethane foams, polymeric materials, formulated materials, elastomers, adhesives, or CMP pad materials.

Responsibilities

• Lead supplier quality activities for polyurethane foams and related raw materials, additives, and formulation components used in CMP polishing pads.
• Drive supplier performance improvement through corrective actions, audits, process capability reviews, and assessments of foam processes and formulations.
• Support foam qualifications, management of change, and risk assessments for formulation, raw material, and supplier process changes.
• Analyze foam quality issues and lead root-cause investigations using methods such as 8D, 5-Why, and fishbone analysis.
• Understand supplier foam manufacturing processes and how variability can affect downstream CMP pad and customer performance.
• Develop and maintain foam specifications, critical-to-quality requirements, COA expectations, test methods, and quality documentation.
• Collaborate with suppliers on process improvements, capability studies, control plans, sampling strategies, and advanced quality planning.
• Support continuous improvement to reduce lot-to-lot variation, improve yield and reliability, and strengthen foam and CMP pad performance.
• Apply continuous improvement methodologies, structured problem-solving, SPC, and FMEA independently.
• Analyze, synthesize, and summarize complex data to support decisions and actions.
• Partner with Business Units, Procurement, R&D, and Operations to ensure continuity of supply for critical foam materials and products.
• Monitor supplier metrics and provide visibility and escalation to cross-functional teams as needed.
• Participate in Business Continuity Planning and risk mitigation for critical suppliers and high-impact materials.
• Train suppliers on requirements and expectations, including change control and quality-system standards.
• Travel up to 10% domestically or internationally and travel to a local manufacturing plant.

Benefits

• Competitive base salary range of $85,500–$125,500 based on years of experience.
• Generous 401(k) plan with employer match.
• Health, dental, and vision insurance packages.
• Flexible work schedule.
• 11 paid holidays per year.
