Introduction to the job

At ASML, we manufacture the complex lithography machines used by chipmakers to produce microchips, leading the way to better and cheaper CPUs, GPUs and memory. Did you know that the latest smartphones like the iPhone 14, fastest laptops and smartest cars are all available thanks to our technology? To keep pace with market demands, our lithography machines are getting faster, and chip patterns are getting smaller.

At the Metrology Software department, we focus on the field of lithography metrology – metrology meaning ‘the science of measuring’. We compensate for sub-nanometer inaccuracies that inevitably creep in due to material imperfections, temperature fluctuations, and/or atmospheric pressure changes.

Metrology software coordinates the behavior of powerful mechatronic modules to enableASML’s machines to position a silicon wafer in less than a second, with nanometer accuracy! For example, one such module accelerates at 7g, that’s faster than a fighter jet!

Scanner metrology software is a unique field for software engineers looking to combine their problem-solving skills, interest in physics and programming expertise in one of the world’s most innovative industries.

Our metrology software measures and processes the physical imperfections, and calculates how our hardware should behave to address these imperfections, coordinating the many, physical components to maximize system performance.

Role and responsibilities

As an ASML software engineer, you will design and implement real-time computational models in C++, translating and then fitting your models into the scanner’s wider software architecture.
You will work on a range of physics-based challenges that our lithography machines face, collaborating with our functional metrology engineers. They create models of machine processes, which predict how our hardware should behave to ensure our machines run with speed and accuracy.

To achieve this, you use data from the machine’s sensors as the input for the metrology models that control the many actuators in the system. These metrology models then help our machines meet their performance requirements from both a time and accuracy perspective. Code maintainability is another key area, where you must work across a huge code base, while also guaranteeing the future of our software.

The work at ASML is challenging – you will often have strict deadlines, dozens of stakeholders, millions of lines of C++ code and hundreds of undocumented use cases and behaviors – but it is also exciting. You have to solve problems no other company has to solve and it’s up to you to help push these unique machines right to the edge of their physical limits.

You will be part of a multi-disciplined and friendly team, always available to provide guidance or a second opinion. Whatever you need, your colleagues are there to support you, whether helping directly with a problem or giving you the space to experiment to find a new solution.

Education and experience

BSc or MSc education level


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:

  • Background in computer science or software engineering
  • C++ programming with strong knowledge of architectural patterns and object-oriented design and implementation
  • Experience with the agile/scaled agile (SAFe) way of working;
  • Awareness of test-driven development and behavior-driven development;
  • Knowledge of Python, Julia, CI/CD, Boost, and/or MATLAB is a plus.
  • We would also welcome experience with:

We would also welcome experience with:

  • Machine development or embedded systems development;
  • Sensors and/or control loops;
  • Digital signal processors;
  • Robotics;
  • Automotive;
  • Machine learning;

ASML is a highly dynamic environment, which requires a:

  • Cooperative, flexible, problem-solving mindset where you can work in a complex, dynamic environment with changing requirements;
  • Passion for learning more about complex subjects, especially physics and mathematics;
