Job Category

Optics, Physics




Do you have a creative way of thinking and do you like to be challenged in solving complex problems? If so then you will enjoy working in our EUV Laser Light Creation and Performance department! It’s a great opportunity for professional development and personal growth. Especially when you are a true self-starter who likes to understand and improve a highly complex laser system.

Job Mission

As an Optical Design Engineer you are part of a multidisciplinary product development team (thermal, mechanical, electrical, software and industrialization) that designs and improves the Laser in the EUV Source. You achieve your goals by building knowledge of the product design, functionality and fundamental working principle. You do this by coming up with creative solutions, creating optical models and translating the outcome into practical designs. Once the concept is understood, you detail and implement the design together with your multidisciplinary team and supplier(s). The last step is to verify the design and work side by side with the industrialization team to also enable the efficient production and service activities.

Job Description

Your daily activities are:
Product Development
-Come up with practical solutions which fulfill the customer needs and solve field issues.
-Use optical modelling to come to design choices.
-Align your designs with team members from different disciplines and our suppliers.
-Document specifications, identify technical risks and mitigation options and prepare design reviews.
Testing & Verification
-Built understanding of phenomena that act as bottlenecks to increase system performance.
-Verify and improve the optical models based on the actual system performance.
-Document lessons learned and spread the knowledge within your team.
Field & Factory Support
-Support the field and factory teams during the introduction phase of the new design.


Master Degree in Optics or (Laser) Physics


Minimal of 4 year industry experience in testing and designing high end (laser) optics setups

Personal skills

-Ability to overview and understand the physical operation principal of complex optical system and generate detailed modeling and simulation to predict its performance.
-Understanding of high-level system requirements and cascading of these requirements into lower-level modules, sub-modules and component design specifications.
-Proven experience in using at least 2 of the following packages to model, design and analyze optical/ laser systems: Zemax, FRED, MATLAB
-Experience in modeling physical/wave propagation of laser beams is a big pro
-Define and build-up optical tests setups.
-Analyze test results (using Excel and/or MATLAB).
-We expect you to act as a professional:
-Have strong written and oral communication skills in English.
-Express a ‘can-do’ and problem solving mentality.
-Commitment to deliver on time.
