ASML gives the world's leading chipmakers the power to mass produce patterns on silicon, helping to make computer chips smaller, faster and greener. ASML is the leading supplier to the semiconductor industry, driving lithography system innovation.

Our Metrology department facilitates solutions that can quickly measure imaging performance on silicon wafers and feeds that data back into the lithography system in real-time, helping to keep lithography performance stable in high-volume chip manufacturing.

At ASML our metrology software orchestrates the behavior of powerful mechatronic modules, so that together they achieve an extraordinary combination of speed and accuracy. For example, one such module (a wafer stage), accelerates faster than a fighter jet to enable the ASML machine to position a silicon wafer in less than a second, with nanometer accuracy! As well as using metrology systems to position wafers, ASML also uses metrology systems to measure and compensate for sub-nanometer inaccuracies that inevitably creep in due to material imperfections, temperature fluctuations, and/or atmospheric pressure changes. To achieve such challenging results, the best metrology systems ever imagined are required.

We are looking to hire strong Python Software Designers who enjoy translating functional requirements into lean software designs.

Job Mission

Unlocking the full potential of the Metrology scanner to do the perfect exposure in a nanometer world!

Job Description

Solutions of the Metrology Functional Group are implemented in software by the Metrology Software Department. Your role is to design high-quality software, allowing fast and efficient delivery of complex metrology functions.

The main tasks and responsibilities are:

Bachelor or Master in Computer Science, Software Engineering or equivalent is strongly preferred.


• We have a strong preference for a senior experienced Software Engineer (object oriented design);
• Experience working in a multidisciplinary setting;
• A proven track-record in Python (not scripting, but implementing production code);
• Work experience with C/C++ and Linux;
• You have a good understanding of mathematical and physical concepts and translating them to clean software designs;
