Over deze vacature

Is your drive to work ‘where the heat is’? Being the key in achieving the ultimo goal? Then working on ASML’s EUV source system to keep Moore’s law alive is your job! The essential aspect of bringing value is to generate new ideas and ensure that they are being worked out and delivered according to the specification as agreed with our customers around the globe… and that is where you come in!


Job Mission

The mission for the Design Engineer is to design and industrialize the next generation of optical components of our CO2-laser system as part of the EUV source. Increased optical power and better, more stable performance is a constant demand for our systems. Also, to improve usability by our customers and our Customer Support teams, the optical system has to become more automated and more robust to failure and restart. This requires mastering the full chain from requirement specification, design, and integration into the optical platform of high power optical elements and metrology systems. It is the task of the design engineer to develop new solutions or improve existing ones, and present those to the all stakeholders in the project. For this, you work with a large, multidisciplinary team. It includes the hand-over to Customer Support and manufacturing and to provide support in case of complex issues they cannot handle. This means that as design engineer, you are the module owner, being the spider in the web: you work very closely with the different groups within ASML (mechanics, software, electronics, manufacturing, customer support, ..) to make sure that in the end your specified deliverable proves to be working with a happy customer as the logical end result!

Job Description

Identify and solve complex high-power laser optics issues. Drive to structurally fix them, either by prevention or by delivering advanced diagnostic tooling to shorten the repair time.

Key in this position is to improve the optical components materials and coatings to improve system reliability and availability, while enabling the regular power increases required by our customers. As you also communicate with other competencies to make your deliverables happen, this responsibility requires a high level of multidisciplinary technical knowledge combined with good communication skills and a big drive to make things happen.

  • Apply broad knowledge in optical components, sensors, actuators and data analysis tools to drive control system improvements to enable continuously increased power and system availability
  • Have thorough technical understanding of the overall complex CO2 system
  • Specify optical requirements and deliver tools, test and analysis methodology, for performance monitoring and optimization. -Serves as a technical expert/owner for one or more optical subsystems
  • Create and perform test plans to verify if the design is meeting the requirements, on module level and integrated in the overall system
  • Investigate, analyze & troubleshoot issues in a structured way, find the root cause and turn this into plannable actions to contain and solve the issues structurally
  • Present results to the project team and other stakeholders. Interacts with cross-functional groups (engineers and scientists, worldwide customer support personnel, manufacturing personnel, upper management, marketing, external customers). Crosses functional boundaries and builds constructive and effective relationships throughout the whole organization
  • Support systems in the factory and the field. Travel (Asia / US) can be expected
  • Create knowledge transfer to the factory and customer support
