In a nutshell


Veldhoven, Netherlands

Introduction to the job

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 analyze 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

Role and responsibilities

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.

Job Description

As a Virtual Compute Platform (VCP) platform Java developer you are part of a Scrum Team. Our Scrum Teams are 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 units 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. We apply open-source technologies like Kafka as well as some licensed products. Current platform architecture is based on DC/OS, we invest the introduction of K8S on this platform.
