Optical & System Designer – Illumination (m/f/x)

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.

Do you want to design optical systems that do not yet exist? In the Illumination Optical and System Design team, we work on the physical questions behind the world's most precise optical systems — for the next generation of semiconductor lithography. If you are passionate about physics and want to make full use of genuine technological freedom in design, this is the right place for you.

• You design optics for new products or generations, optimize their functionality, and ensure the optical performance of our systems—analytically, numerically, and in close collaboration with colleagues from mechanics, electronics, and other optics-design teams.

• As a team member, you translate complex, interdisciplinary requirements—thermal influences, packaging constraints, and manufacturing limits—into robust optics and system designs.

• You bring initiative, challenge existing approaches, and actively contribute to continually rethinking solutions.

• Completed science-based Master’s degree or PhD (preferably Physics, Optics, Photonics, or related fields)

• Professional experience in academia or industry (e.g., as a Postdoc) is a plus but not required

• Basic knowledge of scientific programming (e.g., Matlab, Python)

• Experience in designing optical systems, both imaging and non-imaging optics, with ray-tracing methods and automated optimizers — the specific tool is secondary (e.g., Zemax/OpticStudio, CodeV, etc.)

• Strong natural science curiosity and willingness to independently dive deep into the physics of lithography systems and their modeling

• Experience with AI methods (e.g., for optimization or data analysis) is welcome but not required

• Communication strength: you can explain complex technical concepts to colleagues from other disciplines

• Enjoyment of self-motivated, structured work and learning in an interdisciplinary team
