The Wilton Factory Optics, Chemical Engineer joins the Optical Fabrication organization to own and optimize manufacturing chemistries for milling and polishing operations. This role involves managing coolant systems, polishing slurries, filtration practices, and fluid management processes to ensure high-quality surface finishes and equipment performance. The engineer will develop standard work, establish chemical specifications, monitor parameters like pH and conductivity, and lead root cause investigations into defects such as corrosion or contamination. Key technical skills include experience with industrial coolants, slurry chemistry, and advanced manufacturing techniques like Six Sigma and DOE. Candidates should be proficient in tools such as JMP, Minitab, Python, and SAP while managing chemical safety and supplier relations. The role addresses critical challenges in precision manufacturing for the semiconductor industry, specifically focusing on maintaining stable, repeatable chemical processes to protect optical quality and enhance production efficiency.
Own and optimize manufacturing chemistries for milling, grinding, and polishing operations including coolants, slurries, and adhesives.
Establish and maintain chemical specifications, operating windows, process controls, and standard work for fluid management.
Develop monitoring systems to track key parameters like pH, conductivity, viscosity, and particle size distribution.
Use SPC and data analysis to detect process drifts and lead corrective actions for manufacturing excursions.
Lead root cause investigations into surface defects, contamination, and chemical stability issues in production.
Execute projects to improve chemical life, reduce waste, and lower operating costs using Lean and Six Sigma methods.
Manage supplier relationships to qualify new materials and ensure consistent quality of critical process chemistries.
Ensure all chemical handling, storage, and disposal practices comply with EHS regulations and safety standards.
What we're looking for
Bachelor's degree in Chemical Engineering, Chemistry, or a related technical discipline.
Minimum of 5 years of experience in manufacturing, process engineering, chemical process development, industrial fluid management, or a related technical environment.
Experience with industrial coolants, polishing slurries, process fluids, cleaning chemistries, and chemical delivery systems.
Strong understanding of fluid chemistry, contamination control, filtration, chemical compatibility, and process monitoring methods.
Experience applying SPC, statistical analysis, root cause analysis, and data-driven problem solving in a manufacturing environment.
Experience in optical fabrication, precision manufacturing, semiconductor manufacturing, advanced ceramics, glass processing, or ultra-precision surface finishing (preferred).
Proficiency with JMP, Minitab, Power BI, Python, Excel, or equivalent data analysis and visualization tools (preferred).
Familiarity with coolant reclamation, filtration, centrifugation, ultra-filtration, DI water systems, chemical delivery systems, and waste treatment processes (preferred).
