Some people are really surprised when they learn that ASML has very large software departments where people work with Java, C#, Big Data, machine learning, Algorithms and UX Design.

Solving problems is key within our software departments. It is a sound mix being challenged every day and using your coding skills in a smart way to find the best solution. You just need to be good at what you do.

"The way we release our software at ASML demands that developers should be flexible; system requirements may change from month to month. We need people who understand this way, and who can create in attainable phases, a software architecture that is future proof and functional for multiple customers." - Marc Frijns, Software Architect

This is your chance to prove that you've got the skills to solve complex problems - good luck!
