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 (EUV laser source creation).

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.

Job Mission

We are looking for a talented Opto-Mechanical Engineer with a strong and diverse background in mechanical design for optical assemblies to join our DUV Platforms team.This position will be a key contributor in sustaining and developing the optomechanical assemblies in our DUV lasers.

Job Description

  • Mechanical design of optical assemblies

  • Design mechanisms for positioning and aligning optics (translation, tip/tilt focus, androtation).

  • Designing mounts for prisms, gratings, mirrors, and other optical components

  • Calculating mechanical tolerance stack ups, specifically as they effect optical alignment

  • Analyze the mechanical and thermal stability of optical assemblies using FEA and other analytical tools.

  • Contribute to the development of alignment and assembly processes for optical instruments

  • Collaborate with other engineering groups such as Optics engineers and Systems engineers on optical sub-assembly design.

  • Collaborate with vendors on the fabrication of mechanical parts, mechanisms, and optics

  • Other responsibilities may be added as business conditions arise


  • Requires a B.S in Mechanical or Optical Engineering. (M.S or Ph.D. Preferred)


  • Minimum of 5 years opt-mechanical design experience is required.
  • Expert knowledge of opto-mechanics

  • Experience designing optical assemblies

  • Experience designing mounts for optical components

  • Proficient with CAD software. Creo is preferred.

  • Finite Element Modeling experience (structural, thermal, vibration)

  • Strong working knowledge of optics

  • Experience with optical adhesives

  • Familiar with outgassing and low outgassing materials

  • Ability to do mechanical tolerance analysis with an understanding of the impact on optical performance

  • Experience working with machine shops and optics fabricators

  • Bonus skill: working knowledge of an optical ray trace software (Zemax, Oslo)
