CNC Process Engineer

Process Engineer

ASML US brings together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, more energy-efficient microchips. We design, develop, integrate, market and service these advanced machines, which enable our customers - the world's leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics.

Our headquarters are in Veldhoven, the Netherlands, and we have 18 office locations around the United States.

This position is for a highly skilled process engineer with an innovative attitude and motivation to join ASML Wilton Factory Optical Fabrication team. This role supports daily manufacturing operations, drives continuous improvement, and partners closely with engineering, quality, and production teams to advance equipment capability and product performance.

Role and 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, document, and improve CNC machining processes, programs, and workflows for new and existing products.
• 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 and 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.

Required Qualifications

• 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

Preferred Qualifications

• Experience in a semiconductor or CNC manufacturing environment
• Knowledge of Design of Experiments (DOE) and Six Sigma methodologies
• Solid Modeling Software, NX
• CAM 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

Additional Information

• 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
• Candidates must be legally authorized to work in USA
