Software Engineering Internship: Python tool development

IntroductionThe Mechanical Development (MDEV) cluster at ASML designs, builds, and tests mechanical systems that are integrated into our advanced lithography machines. Our team ensures that these systems are manufacturable, transportable, and serviceable throughout the product lifecycle. To improve engineering efficiency, we are developing automation tools that support simulation workflows. These tools help reduce cycle time and enable faster, more informed design decisions.Your assignmentAs a Software Development Intern, you will contribute to the enhancement of ASML’s internal simulation toolkits. These tools interface with professional physics simulation software and are built to support engineers in managing and comparing complex models. You will work on a standalone application that interacts with simulation software, helping users search, retrieve, and compare model metadata across revisions.Your main responsibilities will be:Review and improve existing code architecture for better performance and scalabilityDevelop new features and tools to support simulation workflowsDocument your work clearly and prepare optional user workshopsCollaborate with other developers using version control toolsPlan and track your progress using a dashboardIntegrate your work with simulation platforms such as ANSYS, NX SC3D, or VCollabEnsure tools are user-friendly and aligned with engineering needsYour profileTo be suitable for the internship, you:Are pursuing a bachelor’s or master’s degree in software engineering or mechanical engineeringHave experience with Python and understand programming patternsAre collaborative and communicate effectively in a team settingAre analytical, with a strong attention to detailAre proactive in identifying and solving technical challengesThis is a bachelor/master apprentice internship for minimum 5 months, minimum 4 days per week. The start date of this internship is as of February 2026.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 be perform your internship. In case 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).Inclusion and diversityASML is an Equal Opportunity Employer that values and respects the importance of a diverse and inclusive workforce.
