Introduction to the job

Sub-nanometer positioning of the wafer stage and the reticle stage in our ASML machines is enabled by stage position sensors. Within the Bottom cluster we are looking for a designer who can contribute to the realization of these sensors.

Role and responsibilities

The Stage Position Measurement (SPM) group within the sector Development & Engineering (D&E) is responsible for interferometer and encoder based position measurement systems for wafer stages and reticle stages.

For newly developed systems we are responsible for the specification, design, integration and qualification of our position measurement systems. These developments are done in close cooperation with measurement system suppliers outside of ASML.

We're searching for an engineer to strengthen the EXE team. You will be involved in all phases of our product design: from feasibility, development and integration to supporting our installed base.
• You will improve the accuracy, throughput and reliability of our interferometer and encoder based optical position measurement systems by:
oImproving the interferometer and encoder designs together with our suppliers.
o Improving complex algorithms in our drivers and calibrations together with our software teams.
o Improving our electronics and mechanical designs together with dedicated electronics and mechanics development teams.
• You like to investigate complex issues related to our measurement systems and work together with other ASML teams to define containments and structural solutions.
• You will be working in a young, enthusiastic team with a nice atmosphere, where we also pay attention to non-work related activities.

Education and experience

University, Master in Physics or Mechanical Engineering

• 0 to 2 years development experience
• Experience with optical sensor development or more specifically interferometers
• Strong in mathematics
• Matlab for data analysis and simulation


Working at the cutting edge of tech, you’ll always have new challenges and new problems to solve – and working together is the only way to do that. You won’t work in a silo. Instead, you’ll be part of a creative, dynamic work environment where you’ll collaborate with supportive colleagues. There is always space for creative and unique points of view. You’ll have the flexibility and trust to choose how best to tackle tasks and solve problems.
To thrive in this job, you’ll need the following skills:
• Team player
• Pragmatic with result oriented attitude
• Take the initiative
• Good communication and stakeholder management skills
• Excellent command of English language
• Can adapt quickly to changing scope and/or circumstances
