Senior Development Engineer Fluid Mechanics (Flow & Pressure) (f/m/x)

ZEISS Semiconductor Manufacturing Technology​

​

Enabler for smaller, more powerful, and more energy-efficient microchips​

​

Working for tomorrow today. ​

Around 80 percent of all microchips worldwide are produced using ZEISS technologies. As the centerpiece of every electronically controlled system, they have become an integral part of our everyday lives – whether in smartphones, smart homes or smart factories. ZEISS is a technology leader in the field of semiconductor manufacturing equipment. With high-precision lithography optics, photomask systems and process control solutions, ZEISS enables the production of ever smaller, increasingly powerful, and more energy-efficient microchips, and thus plays a pivotal role in the age of micro- and nanoelectronics.

Your Role

To manufacture defect-free photomasks for the latest-generation semiconductor lithography, we develop optical metrology solutions.

The architecture of gas flows within these systems plays a key role in achieving the highest levels of measurement accuracy and system lifetime.

• You will be responsible for the flow and pressure architecture of highly complex optical metrology systems.
• You will translate high-level requirements into technical specifications for design modules, materials, and cleanliness processes.
• Using CFD, 1D, and DSMC models, you will analyze and optimize flow behavior, pressure conditions, and contaminant transport.
• You will develop outgassing and leakage budgets, as well as concepts for purge gas management, mini-environments, and vacuum systems.
• You will support the verification of requirements and assess technical deviations and optimization opportunities.
• You will work closely with interdisciplinary development teams and relevant interfaces and represent your topics within projects and stakeholder groups.

Your Profile

• You have an excellent university degree in aerospace engineering, process engineering, mechanical engineering, physics, or a comparable field.
• You have a strong background in fluid mechanics, vacuum technology, gas transport, or contamination control.
• You have experience modeling complex flow and pressure systems, particularly using CFD; knowledge of DSMC or 1D system simulations is an advantage.
• You are experienced in deriving technical requirements, developing budgets, and performing model-based design verification.
• Ideally, you have knowledge in areas such as outgassing, leakage, cleanliness, partial pressure analysis, or residual gas analysis.
• You enjoy working in interdisciplinary teams and are confident in coordinating with a wide range of interfaces and stakeholders.
• Very good written and spoken German and English skills
