Over deze vacature

ASML is one of the world’s leading manufacturers of semiconductor-chip-making equipment. A majority of the world’s microchips receive their critical lithographic patterning in machines made by ASML. In addition, ASML produces metrology tools and advanced applications to analyse and optimize the performance of the customer production process. A large part of the development work linked to these tools is software driven. When people think ‘software’, they often think of companies like Google or Microsoft. Even though ASML is classified as a hardware company, we in fact have one of the world's largest and most pioneering Java communities

Job Mission

Develop software services in a Java cloud native driven microservice architecture. The components you will be working on deliver an abstraction layer between the ASML core equipment (scanners and metrology, collection of data) and the intelligent correction software engines that rely on this data. Next to the collection and storage of the data also deliver scheduling, notification and other generic building blocks. The software platform you deliver shall simplify the development and updates of the correction engines and enable future data driven use cases to be developed on top of your platform.


As a Virtual Compute Platform (VCP) platform Java Developer, you are part of a Scrum Team. Our Scrum Teams are relatively large; teams are composed of about 8-10 engineers. You develop in Java 8, migration to Java 11 is planned. The development is done using a Bamboo based CI/CD pipeline. You test your code at several stages before you deliver. We have automated unit and some integration tests. We measure coverage in SonarQube. Coverage levels are extremely high.

As we develop platform software you will also be able to work on larger test clusters composed of many compute, edge, storage and master nodes.

  • Continuously improve to drive #issues down
  • Act as an expert, not as an executioner; help clarify requirements before start and during development. Seek understanding and be able to explain to drive the creation of the right product in the right timeframe.
