Job description
Introduction
ASML US, LP 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 including main offices in Wilton, CT, Chandler, AZ and San Jose, CA.
Job Mission
ASML is the world’s leading provider of lithography systems for the semiconductor industry, manufacturing complex machines that are critical to the production of integrated circuits or microchips. This position is for a First Line Support Production Engineer with an innovative attitude to work in the Production Engineering department in Wilton Factory (Wilton, CT). The candidate will work with cross-sector employees to provide rapid responses to resolve production disturbance notices related to engineering issues. In addition, the candidate will perform the engineering steps listed in the production operator dashboard (POD) to support output
As a First Line Support (FLS) Production Engineer, you’ll work directly with manufacturing to solve technical issues that arise during the build, test, and qualification of complex high-tech products. This is a highly hands-on engineering position, with approximately 75% of your time spent in the cleanroom supporting production and troubleshooting issues that could impact manufacturing output.
You’ll provide rapid engineering support for problems involving mechanical assembly and alignment, glass-to-metal bonding, flow and thermal performance, tooling and test stands, module testing, and final qualification. You’ll evaluate failed parts, perform root-cause analysis, develop troubleshooting guidelines and OCAPs, and partner with multidisciplinary engineering and manufacturing teams to implement both immediate fixes and longer-term improvements.
Beyond day-to-day troubleshooting, you’ll contribute to PFMEA, manufacturing procedures, diagnostic qualification, technical work instructions, DOA root-cause analysis, and cycle-time and labor-hour improvements.
What We’re Looking For
Bachelor’s degree in Mechanical Engineering or another engineering discipline with 2 years of experience, or a Master’s degree in an engineering field.
Hands-on experience with mechanical assembly, alignment, tooling, and test equipment.
Working knowledge of epoxy application in opto-mechanical designs.
Experience with detectors, electro-optical devices, and opto-mechanical constructions.
Ability to read and interpret mechanical, optical, and electrical technical drawings.
Strong troubleshooting and root-cause problem-solving capabilities.
Ability and interest in working approximately 75% of the time in a cleanroom/manufacturing environment.
Strong ownership, communication, teamwork, and continuous-improvement mindset.
Knowledge of MATLAB, LabVIEW, and Python.
Additional Experience That Stands Out
Experience with SPC, FMEA, NX, Teamcenter, SAP, optical-electrical sensors, geometric or wave optics, data/signal processing, statistics, or software development would be valuable additional experience.
