Job description

Job Summary ASML Wilton is seeking a Senior Process Engineer to join the Wilton Factory Optics team with primary ownership of mechanical inspection processes. This role is responsible for process development, stabilization, and daily performance across automated and manual mechanical 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. Job Description 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. The engineer will manage mechanical inspection performance, inspection control strategies, and inspection output quality while ensuring consistent results across tools, people, and shifts. The mechanical 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 mechanical 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 Education and Experience • 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, mechanical inspection methods, and process development • Demonstrated ability in structured problem solving, data analysis, RCA, and process improvement Skills • Strong understanding mechanical inspection best practices and tooling mechanics for accurate measurements • Proficiency with manual and automated mechanical 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 Physical Requirements Work includes time spent on the fabrication floor, interaction with visual inspection 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. Candidates must be legally authorized to work in the U.S. without sponsorship Additional Responsibilities: There is 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.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.
