Job Summary

ASML Wilton is seeking a Senior Process Engineer to join the Wilton Factory Optics team with primary ownership of CNC deterministic polishing processes.

Job Description

The Senior Process Engineer will operate as a technical leader within Wilton Factory Optics with end-to-end ownership of CNC deterministic polishing processes. Responsibilities include defining and optimizing process parameters, ensuring measurement stability, selecting tooling, and understanding machine behavior. The engineer will manage CNC deterministic polishing performance, environmental control strategies, and measurement output quality while ensuring consistent behavior across tools and shifts.

Responsibilities

  • Define and optimize process parameters
  • Ensure measurement stability
  • Select tooling
  • Understand machine behavior
  • Manage CNC deterministic polishing performance
  • Manage environmental control strategies
  • Manage measurement output quality
  • Ensure consistent behavior across tools and shifts
  • Lead the introduction and qualification of new fixtures, tools, software, and machine upgrades
  • Interpret final results from interferometry, profilometry, and surface inspection data and turn them into actionable decisions
  • Establish strong process control: define process windows, capability targets, and long-term monitoring systems
  • Use JMP or Minitab to identify variation, drift, and chronic stability risks, ensuring processes are robust, documented, and repeatable using SPC analysis tools
  • Maintain process specifications, work instructions, and standard work while driving alignment across production and support teams
  • Collaborate daily with production technicians, supervisors, grinding and polishing teams, quality, equipment engineering, and maintenance, balancing immediate production needs with structured long-term improvement projects
  • Build process stability that prevents rework and FPY loss
  • Detect and eliminate sources of variation impacting FPY and yield
  • Lead structured RCA using statistical and analytical methods
  • Ensure corrective actions are verified, embedded, and sustainable
  • Own full 6P readiness for process, material, or equipment changes

Education and Experience

  • BS, MS, or PhD in Mechanical, Optical, Materials, or related engineering field
  • Minimum 5 years of experience in optical fabrication and CNC deterministic polishing machine
  • Experience in tooling mechanics, CNC deterministic polishing interpretation, and process development
  • Demonstrated ability in structured problem solving, data analysis, RCA, and process improvement

Skills

  • Strong understanding of CNC deterministic polishing and tooling mechanics for accurate measurements
  • Proficiency with interferometry, profilometry, and surface inspection tools
  • Experience using JMP, Minitab, or equivalent statistical software
  • Strong communication, cross functional collaboration, and leadership in a production environment
  • Demonstrated capability in 6P readiness, structured RCA, and verification driven corrective action

Physical Requirements

  • Work includes time spent on the fabrication floor, interaction with CNC deterministic polishing equipment, and periods of standing or walking
  • The role may require lifting materials up to 35 pounds
  • Visual acuity for inspection tasks is required
  • The environment includes exposure to noise, vibration, and manufacturing equipment while wearing appropriate PPE
  • Must be willing to work in a clean room environment, wearing coveralls, hoods, booties, safety glasses and gloves for entire duration of shift

Additional Responsibilities

  • Potential for exposure to strong magnetic fields, high voltage and currents
  • This position requires access to controlled technology, as defined in the United States Export Administration Regulations (15 C.F.R. 730, et seq.)
