About The Position

ASML Wilton is seeking a Senior Process Engineer to join the Wilton Factory Optics team with primary ownership of CNC deterministic polishing processes. This role is responsible for process development, stabilization, and daily performance across CNC deterministic polishing operations. The position requires a deep technical understanding of optical fabrication, strong analytical capability, and the ability to drive sustainable improvements in a fast-paced production environment. The engineer will directly support output, yield, and quality targets—including improving First Pass Yield (FPY) through stable, predictable, and well controlled process behavior. This role requires a proactive engineering mindset: anticipating issues before they impact production, driving structured 6P readiness, performing thorough RCA, and continuously evaluating new technologies to strengthen long-term process control. This is not a reactive support role; the expectation is ownership, foresight, and continuous improvement. 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. The CNC deterministic polishing scope includes control of tooling, environment, fixturing, and other factors influencing surface figure and CNC deterministic polishing output. The PE will lead the introduction and qualification of new fixtures, tools, software, and machine upgrades, and will interpret final results from interferometry, profilometry, and surface inspection data and turn them into actionable decisions. A key responsibility is establishing strong process control: defining process windows, capability targets, and long-term monitoring systems. The PE will use JMP or Minitab to identify variation, drift, and chronic stability risks, ensuring processes are robust, documented, and repeatable using SPC analysis tools. This includes maintaining process specifications, work instructions, and standard work while driving alignment across production and support teams. The engineer will 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.

Requirements

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
Strong understanding of CNC deterministic polishing and tooling mechanics for accurate measurements

Demonstrated capability in 6P readiness, structured RCA, and verification driven corrective action
Work authorized in the United States without the need for employer sponsorship now or in the future.
Legally authorized to access controlled technology (as defined in the United States Export Administration Regulations) prior to beginning work.
