About The Position

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 with innovative attitude and motivated Process Engineer 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.

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.
