EUV Tech stands at the forefront of the next era in advanced semiconductor manufacturing, delivering new and innovative solutions worldwide.

If you are looking to push the limits of cutting-edge technology in an impactful role with a talented team, we would love to hear from you!

About the Role

We are seeking an onsite Senior Mechanical Engineer to join our R&D Light Sources team. The Sr Mechanical Engineer will collaborate closely with scientists, optical engineers, electrical engineers, and system integration specialists to design the next generation of EUV light sources. The Sr Mechanical Engineer will work from concepts ranging from detailed CAD models to basic verbal descriptions, transforming them into functional, manufacturable mechanical components and assemblies for complex, high-vacuum, high-precision systems.

Designs must be robust enough for demanding operational environments, including continuous 24 / 7 industrial use. This is a highly hands-on role—beyond design, you will be directly involved in prototyping, assembly, and testing, ensuring that systems meet both performance and manufacturability requirements. The work is fast-paced and agile, with projects often moving quickly from initial concept to deployed product, making this position ideal for someone who thrives in multidisciplinary, rapid-prototyping environments.
