Introduction

The Mains & Safety team within Development & Engineering plays a key role in designing safety-critical handling systems for ASML's lithography machines. These systems must perform reliably under a wide range of conditions to support system uptime and product quality. This internship supports that mission by improving how we validate the reliability of I/O modules returned from the field. You will help the team strengthen diagnostic capability while contributing to lower environmental impact and reduced Cost of Goods. This is a chance to gain hands-on experience in a highly innovative and international environment.

Your assignment

You will design and implement a complete testbench that combines hardware and software to verify the safety, performance, and functional integrity of PLC-based I/O modules. Your work will help ensure consistent, repeatable, and traceable testing that supports automated decision-making on module reuse or replacement. You will also deliver clear documentation and present your findings to the team.

Your main responsibilities will be:

• Design and build a hardware setup that supports safe and repeatable I/O module testing.
• Develop software that measures key electrical and communication parameters.
• Create automated pass/fail classification and reporting tools.
• Validate the testbench under different operating conditions.
• Analyze test results and support root-cause investigations.
• Document the full methodology and write a clear technical report.
• Present your approach, results, and recommendations to the team.

This is a bachelor/master thesis internship for 3-6 months, 5 days per week (min. 3 days on-site). The start date of this internship is as of September 2026, however starting earlier is possible.
