The mechatronics department for the Projection Optics Box (POB) in ASML’s EUV systems develops ultra-stable structures and actuation solutions for mirror alignment. You will contribute to improving system stability by detecting unintended mechanical shortcuts between structural frames. These shortcuts can reduce performance and are difficult to localize with visual inspection alone. In this internship: you will help turn measurement data into actionable insight. Your work supports high-precision performance in EUV manufacturing.
In complex mechanical systems, hidden connections between frames can disturb dynamic behavior and reduce positioning accuracy. In this internship you will investigate how changes in dynamic behavior reveal the presence and location of these shortcuts. Your main responsibilities will be:
Analyze measurement data to detect changes in system dynamics
Perform modal fitting on frequency response data
Compare results with reference data from nominal conditions
Identify patterns in mode shape variations linked to structural shortcuts
Develop software tooling for data analysis and visualization
Validate findings with engineering insights and simulations
Present results and recommendations to the team
This is a master non-thesis internship for minimum 4 months and maximum 6 months, for 5 days per week (2 days on-site). The start date of this internship is as of September 2026.
To be suitable for the internship, you:
Are pursuing a master’s degree in mechanical engineering, mechatronics or a related field
Have experience with system identification and dynamic modeling
Have practical experience using MATLAB or similar tools
Show analytical thinking and a structured working approach
Are collaborative and can also work independently

Who are we?
ASML is an innovation leader in the global semiconductor industry. We make machines that chipmakers use to mass produce microchips. Founded in 1984 in the Netherlands with just a handful of employees, we’ve now grown to over 40,000 employees, 143 nationalities and more than 60 locations around the world.
What do we do?
We provide chipmakers with hardware, software and services to mass produce patterns on silicon through lithography. Our lithography systems use ultraviolet light to create billions of tiny structures on silicon that together make up a microchip. We push our technology to new limits to enable our customers to create smaller, faster and more powerful chips.
Who are our people?
While you may think that only engineers and mathematicians work at ASML, you'll be surprised to find out that our people come from a wide variety of backgrounds. Across ASML, we have dedicated teams that manage customer support, communications and media, IT, software development and more. Every team in the company is essential for pushing our technology and the industry forward.
If you love to tackle challenges and innovate in a collaborative, supportive and inclusive environment with all the flexibility and freedom to unleash your full potential, ASML is the place to be.
