Computer Science | Software Engineering internship: diagnostics tool modernization

Introduction

Join ASML’s Machine Conditioning Diagnostics team and help modernize critical software that ensures precision in our wafer stage systems. Our scanners rely on advanced encoders for sub‑nanometer accuracy, but legacy tools make error detection and recovery challenging. Your work will transform these tools into a robust maintainable Python‑based solution, supporting ASML’s mission to push the boundaries of semiconductor technology.

Your assignment

You will reimplement a key diagnostics tool currently built in MATLAB and integrated into our internal platform. This modernization will improve maintainability, deployment, and integration with existing workflows.

Your main responsibilities will be:

• Analyze the current MATLAB‑based diagnostics implementation, and study existing Python‑based implementations within Metro Analyzer.
• Design and develop a Python‑based replacement for the legacy tool.
• Ensure seamless integration within ASML’s diagnostics platform.
• Apply modern deployment practices such as containerization and CI/CD.
• Test and validate the new implementation for accuracy and reliability.
• Document your work for future maintainability.

This is a master’s thesis internship for a minimum of 6 months, minimum 4 days per week (2 days on‑site). The start date of this internship is as of February 2026.

Your profile

To be suitable for the internship, you:

• Are enrolled in a master’s degree in computer science, software engineering, embedded systems, or a related technical field.
• Have strong proficiency in Python.
• Are familiar with MATLAB (a plus).
• Understand version control tools such as Git and GitHub.
• Are analytical, proactive, and collaborative, with an interest in modern deployment practices like Docker.

Other requirements you need to meet:

• You are enrolled at an educational institute for the entire duration of the internship.
• Attach your cover letter with a clear motivation why you are interested in this internship assignment in particular.
• You need to be located in the Netherlands to perform your internship. If you are currently living/studying outside of the Netherlands, your CV/motivation letter includes the willingness to relocate.
• 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).
