Introduction to the job

ASML is one of the world’s leading manufacturers of lithography systems that help enable Moore’s Law and the creation of increasingly powerful and capable electronic devices. Our San Diego-based light source division, Cymer, is renowned for developing both deep ultraviolet (DUV) lithography light sources and next generation extreme ultraviolet (EUV) light sources.We are a multinational company with over 70 locations in 16 countries, headquartered in Veldhoven, the Netherlands.We have 18 office locations around the United States including main offices in Wilton, CT, Chandler, AZ, San Jose, CA and San Diego, CA.

As the world’s leading semiconductor lithography machine (the machine that makes computer chips) manufacturer, ASML enables chip manufacturers to make cheaper, faster, chips, thereby enabling all the technology you use today. The machines we make require high speed, magnetically levitated stages with sub-nanometer accuracy, robotic mask delivery systems, mechatronic devices to shape and correct the laser illumination source, and optical modules that can detect sub-nanometer alignment errors and pattern distortions. Temperature controlled to milli-kelvins, particulate free, and operating in complete vacuum, the technical challenges are endless. Solving these requires expertise in servo controls, mechatronics, mechanical engineering, electrical engineering, embedded software engineering, optics, physics, manufacturing, industrialization, and more. If you like extreme challenges and want to help bring the next generation of technology to the world, then come join ASML.

If you have a passion for technology and innovation you’ll want to check us out. Be a part of ASML. Be a part of progress.

One Company, One Goal, Limitless Innovation. It's our people that make the difference.
