About The Position

ASML Wilton is seeking a Senior Process Engineer to join the Wilton Factory Optics team with primary ownership of visual inspection processes. This role is responsible for process development, stabilization, and daily performance across automated and manual visual inspection 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 visual inspection processes. Responsibilities include defining and optimizing process parameters, ensuring measurement stability, selecting tooling, and understanding machine behavior when applicable. The engineer will manage visual inspection performance, inspection control strategies, and inspection output quality while ensuring consistent results across tools, people, and shifts. The visual inspection scope includes control of tooling, environment, fixturing, and other factors influencing inspection output. The PE will lead the introduction and qualification of new fixtures, tools, software, manual processes, and machine upgrades, and will convert surface inspection data 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. 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, cross factory teams, quality, equipment engineering, and maintenance, balancing immediate production needs with structured long-term improvement projects. The Senior PE is expected to: • 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 Beyond daily support, the engineer is expected to proactively seek, evaluate, and integrate: • Inspection process control methods • Advanced inspection tools • Next generation inspection technologies • Equipment or software capabilities that improve stability, predictability, and throughput

Requirements

BS, MS, or PhD in Mechanical, Optical, Materials, or related engineering field.
Minimum 5 years of experience in optical fabrication and visual inspection.
Experience in tooling mechanics, Mil and ISO inspection standards, and process development.
Demonstrated ability in structured problem solving, data analysis, RCA, and process improvement.
Strong understanding of Mil and ISO visual inspection standards and tooling mechanics for accurate measurements.
Proficiency with manual and automated visual inspection tools.
Experience using JMP, Minitab, or equivalent statistical software.
Strong communication, cross functional collaboration, and leadership in a production environment.
Ability to manage multiple priorities under time sensitive conditions.
Demonstrated capability in 6P readiness, structured RCA, and verification driven corrective action.
Candidates must be legally authorized to work in the U.S. without sponsorship.
Qualified candidates must be legally authorized to access such controlled technology prior to beginning work.
