Sr Software Test Engineer


California,San Diego


0005271 Requisition #


Cymer, an ASML Company, is the leader in developing lights sources used by chipmakers worldwide to pattern advanced semiconductor chips. We're at the forefront of technology innovation because of the extraordinary efforts and ingenuity of our employees. Cymer is the world's leading provider of lithography systems for the semiconductor industry. Through innovation, Cymer is an integral part of today’s technology landscape and is leading the light Generation.

One Company, One Goal, Limitless Innovation. It's our people that make the difference.


We are looking for Sr. SW Test Engineers who have a passion for testing software for a distributed control system. Join Cymer/ASML and you will be joining a team that operates in a fast-paced, uniquely innovative and challenging environment to create new-to-industry solutions with rapid productization to support an aggressive commercialization plan for the EUV technology within ASML.

You will work with software test architect and software engineers, you will create test cases and test plans, and you will develop smoke tests, regression tests and software validation tests. You will determine the best test approach to ensure that delivered controls and software sub-systems meets all its functional requirements, by delivering automated test capabilities, employing best in class software quality management tools, ensuring complete software test coverage with the ultimate goal being the superior quality and on-time delivery of the controls and software sub-systems.

And you may ask, what does the control system software do? Well, the control loops involve data exchange at speeds up to 100 kHz while data collection for diagnostics purposes is done at up to 1Khz rate. There is interaction between control loops running on quad core boards and platform software that runs on IBM BladeCenter. Data is stored on board in postgres databases and is shipped via the fab network to data servers in San Diego. And our graphical user interface developed using Qt serves a complex set of users - operators, engineers, scientists and customers. And we don't forget safety, the control system has a Siemens PLC to ensure both human safeties are ensured and machine damage is prevented.

Come and join our journey and you will be challenged and rewarded as you work alongside a group of talented, passionate and fun-loving engineers. You can tell your friends – I work on semiconductor lithography machines that allow the printing of finer features for the next generation of chips that power the innovations in the world today.
