Senior Engineer, Materials Quality Engineering

Senior Engineer, Materials Quality Engineering 

We are seeking a dynamic Senior Engineer to join our Materials Quality Engineering (Supplier Quality) team supporting our regional supplier base and US manufacturing operations. In this role, the engineer will be responsible for assessing and managing quality performance, supplier risk, and capability for Resins used in semiconductor manufacturing, including various thermoplastic and thermoset materials such as PE, PP, fluoropolymers, and other high-performance polymers.  

This position supports the Advanced Purity Solutions Division and the manufacturing plants in Colorado while also working closely with global teammates. The ideal candidate will work with autonomy and sound engineering judgment to lead supplier development, drive continuous improvement, and maintain robust quality systems for critical resin suppliers. The role requires strong collaboration with Commodity Management, Operations, R&D, and Customer Quality teams to ensure continuity of supply and rapid resolution of internal and customer issues related to resin quality, variability, and contamination control. 

In this role you will: 

• Lead supplier quality activities for commodity, engineering, and specialty polymers such as PE, PP, fluoropolymers, and other high-performance resin systems. 

• Drive supplier performance improvement, including corrective actions, audits, process capability reviews, and polymerization process/formulation assessments (raw material handling, polymerization, compounding, mixing, extrusion, packaging, and contamination control processes). 

• Support resin qualifications, change management (MOC), and risk assessments for formulation changes, raw material changes, and supplier process changes. 

• Analyze resin quality issues (impurities, particles, metals/ions, organics, stability, and performance) and lead robust root cause investigations (8D, 5-Why, fishbone, etc.). 

Technical & Resin Engineering Responsibilities: 

• Understand supplier resin manufacturing processes (raw material handling, polymerization, compounding, mixing, extrusion, packaging, and contamination control processes) and how variability impacts downstream customer performance. 

• Develop and maintain resin specifications, critical-to-quality requirements, certificates of analysis (COA) expectations, analytical test methods, and quality documentation. 

• Collaborate with resin suppliers on process improvements, capability studies, control plans, sampling strategies, and advanced quality planning activities. 

• Support continuous improvement initiatives to reduce batch-to-batch variation, improve yield, enhance reliability, and strengthen resin product performance. 

• Understand con
