Senior Engineer, Materials Quality Engineering

Role Overview

• Lead supplier quality activities for organic chemistries used in cleans, etchants, and slurries, including formulation raw materials and critical additives
• Drive supplier performance improvement, including corrective actions, audits, process capability reviews, and chemical process/formulation assessments (batching, blending, filtration, packaging, and contamination controls)
• Support chemical qualifications, change management (MOC), and risk assessments for formulation changes, raw material changes, and supplier process changes
• Analyze chemical quality issues (impurities, particles, metals/ions, organics, stability, and performance) and lead robust root cause investigations (8D, 5-Why, fishbone, etc.)
• Understand supplier chemical manufacturing processes (batching, blending, pH control, reaction steps where applicable, filtration, and packaging) and how variability impacts downstream customer performance
• Develop and maintain chemical specifications, critical-to-quality requirements, certificates of analysis (COA) expectations, analytical test methods, and quality documentation
• Collaborate with chemical 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 chemical product performance (cleans, etchants, and slurries)
• Understand continuous improvement methodologies, structured problem‑solving techniques, SPC, and FMEA and apply them independently in role
• Ability to analyze, synthesize, and summarize complex data sets to drive clear decision making and action
• Partner with Business Units, Procurement, R&D, and Operations to ensure continuity of supply for critical raw materials and formulated products
• Monitor key supplier metrics and provide visibility and escalation to cross-functional teams when needed
• Participate in Business Continuity Planning (BCP) and risk mitigation strategies for critical chemical suppliers and high-impact chemistries
• Train suppliers on key requirements and expectations, including Change Control and quality system standards

Requirements

• Bachelor’s degree in Chemical Engineering, Chemistry, Materials Science/Engineering, or related discipline
• Advanced degree optional; Six Sigma Green Belt or Black Belt strongly preferred
• Experience with supplier quality engineering for chemical raw materials and formulated products (cleans, etchants, slurries) strongly preferred
• 5–7 years’ experience in chemical manufacturing, semiconductor chemicals, specialty chemicals, CMP/slurry manufacturing, or other high-tech manufacturing industries
• Working knowledge of chemical quality systems and controls, including impurity/contamination control, analytical method capability, SPC systems, PFMEA, and control plan development
• Proficiency with statistical analysis software (Minitab, JMP, SAS, 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
