Does contributing to the world’s most advanced lithography machines that create the microchips for the latest and greatest electronic devices make you feel responsible and proud? Do you want to work in a challenging environment with highly motivated (committed, engaged) and highly skilled teams? 

Job Mission

As a Senior Software Design Engineer for Sequence Tooling, you play a central role in the creation and maintenance of mission-critical software applications. You understand the application you work on in detail and are able to achieve maintainable software (architecture), which should be transparent and easy to extend. You also keep a strong focus on the software quality, working with a team of designers, developers, and testers.


The development group of Sequencing Tooling creates modern, web based applications for sequencing and recovery. These tools are used by ASML factory and field engineers to build, install, upgrade and repair the very complex ASML products more efficiently. This is achieved by creating optimized work plans and by supporting operators in the execution of those plans. The tools created by the department thus play an important role in achieving operational excellence and are recognized as such by the highest levels of management. You will be application specialist, software architect and senior developer for the Sequence Runner (SQR) application, the software tool that operators cleanrooms use to execute the carefully prepared action plans.

The SQR team is an agile team consisting of designers, developers and testers, part of a SAFe program. The team has multiple nationalities working both onsite and remote. All communication and documentation is in English. The SQR product is used by many hundreds of people already and is being rolled out to production facilities world-wide. High quality and integration with other applications is key.

Within the SQR team, you take initiative to refine functional stories into clearly defined technical definitions that can be estimated and built. You will work with a Product Owner, Designers, Architects and Product Project leaders. In this position, you will act as Senior Developer. You apply software engineering practices such as requirements engineering (user story definition), object-oriented analysis and design, implementation in Java, testing, and integration.
