Computer Science | Internship: Performance Analytics Tool Development

Within ASML's Development and Engineering sector, the Performance & Integration department helps predict and optimize the performance of advanced semiconductor systems in real-world manufacturing environments. To support this work, the team develops software solutions that process large volumes of measurement data and transform them into actionable insights. This internship offers the opportunity to contribute to data-driven improvements that help engineers understand system behavior and identify optimization opportunities. During the internship, you will work with experienced engineers while developing software solutions that have a direct impact on performance analysis. If you enjoy combining software development, data analysis, and visualization, this internship could be a great fit for you.

• Analyze measurement data and understand relevant performance indicators
• Improve the quality, reliability, and maintainability of existing software tools
• Refactor and optimize software components to increase code reusability
• Develop data visualization solutions and interactive dashboards
• Translate complex datasets into clear and actionable insights
• Collaborate with engineers to identify valuable metrics and reporting needs
• Document software improvements and support knowledge sharing within the team

This is a bachelor/master non-thesis internship for 6 months, 5 days per week (3 days on-site). The start date of this internship is as of February 2027.

In this internship, you will contribute to the development and improvement of software tools used to analyze performance data from advanced semiconductor systems. You will help transform complex datasets into clear insights and improve the quality and maintainability of existing applications. You will work closely with engineers to understand business needs and translate them into practical software solutions.

• To be suitable for the internship, you:
• Are pursuing a bachelor's or master's degree in Computer Science, Software Engineering, Informatics, Mathematics, or a related field
• Have efficient coding skills in Python and/or MATLAB
• Have strong verbal and written communication skills in English
• Are analytical and able to work with complex datasets
• Are proactive and eager to learn in a collaborative environment
• Can structure and improve software code in a clear and maintainable way

This internship offers hands-on experience in software development, data analytics, and visualization within a highly innovative high-tech environment. You will collaborate with experienced engineers, contribute to real-world performance analysis solutions, and develop skills relevant to a future career in software engineering and data-driven development.

• You are enrolled at an educational institute for the entire duration of the internship, and you are at least 18 years old at the start of the internship;
• If you are a non-EU citizen, studying in the Netherlands, your university is willing to sign the documents relevant for doing an internship (i.e., Nuffic agreement);
• You attach your cover letter with a clear motivation on why you are interested in this internship assignment in particular;
• You need to be located in the Netherlands to be perform your internship. In case you are currently living/studying outside of the Netherlands, your application shows the willingness to relocate

This position requires access to controlled technology, as defined in the United States Export Administration Regulations (15 C.F.R. § 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.
