Spherical CNC Process Engineer_ Wilton Factory Optics

About the role

This position is for a highly skilled, innovative, and motivated Process Engineer to join the ASML Wilton Factory Optical Fabrication team. The role supports daily manufacturing operations, drives continuous improvement, and partners closely with engineering, quality, and production teams to advance equipment capability and product performance.

Responsibilities

• Champion a safety-first culture by identifying potential hazards, implementing risk mitigation strategies, and ensuring all work adheres to established EHS safety protocols.
• Develop complex spherical optics on precision CNC Generators, High-Speed Polishers, and centering machines.
• Implement advanced machining strategies and tooling designs for continuous improvement efforts.
• Optimize cycle times, toolpaths, feeds/speeds, and work holding to improve quality and throughput.
• Collaborate with cross-functional teams including production, quality, and metrology to resolve technical challenges and implement sustainable solutions.
• Diagnose and resolve machining issues related to tooling, fixturing, programming, and equipment behavior.
• Partner with maintenance and vendors to address machine performance, repeatability issues, or reliability concerns.
• Analyze machining performance using SPC, capability studies, and data-driven problem solving.
• Define process specifications and control limits; utilize statistical analysis tools (e.g., JMP, Minitab) to evaluate process capabilities and drive data-driven decision-making while maintaining 6P=P from feasibility to production-readiness phases.
• Perform hands-on process trials and support qualification of new equipment, materials, and process changes to enhance production performance.
• Support root-cause analysis and corrective actions for quality deviations or nonconformances.
• Drive 5S and workplace organization around CNC areas.

Requirements

• Bachelor's or Master's degree in Engineering (Mechanical, Optical, Materials, or related field).
• Minimum 10+ years of experience in optical fabrication process engineering or a related manufacturing environment.
• Hands-on experience with optics fabrication techniques, including CNC machining, polishing, and surface inspection.
• Proficient in root cause analysis (RCA) and lean manufacturing tools.
• Familiarity with metrology techniques and quality assurance in optics manufacturing.
• Demonstrated ability to lead problem-solving initiatives and implement process improvements.
• Excellent communication and teamwork skills, with ability to work effectively across different departments.
• Ability to manage multiple priorities and deliver results under tight deadlines.
• Candidates must be legally authorized to work in the USA.
• This position requires access to controlled technology, as defined in the Export Administration Regulations (15 C.F.R. 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work.

Skills

• Manufacturing of spherical or plano optical elements.
• Knowledge of Design of Experiments (DOE) and Six Sigma methodologies.
• Solid Modeling Software, NXCAM Software, Mastercam.
• Proficiency in data analysis tools such as JMP, Minitab, or equivalent software.
• Experience with SAP or MES systems.
• Knowledge of cleanroom protocols and practices.

Physical Demands

• Regular computer work requiring sitting, typing, and precise hand-eye coordination.
• Frequent movement within the optics fabrication floor and office environments.
• Occasional need to lift or move equipment, tooling, or materials weighing up to 20 pounds.
• Required visual abilities include close vision, color differentiation (for inspection and analysis), and the ability to interpret detailed technical information.
• Work performed primarily in an optics fabrication environment that may include exposure to noise, vibration, and various processing equipment.
• Must be able to wear required PPE (personal protective equipment) including safety glasses, hearing protection, and other protective equipment as required in manufacturing areas.
• Ability to analyze complex data, interpret technical documents, and communicate findings effectively.
• Capability to respond to production issues in a timely manner, which may occasionally require extended periods of standing or walking through production areas with various fabrication equipment.
• Some travel may be required to support global manufacturing and supplier interactions.
• Potential for exposure to strong magnetic fields, high voltage, and currents.
