Mechanical Engineer (f/m/d)

Intro

For our location in Freiburg im Breisgau, we are looking for a Mechanical Engineer (f/m/d) to strengthen our Design Engineering team.

At Nex Wafe, we are redefining how silicon wafers are manufactured.

Our innovative epitaxial wafer technology reduces process steps, energy consumption, and CO₂ emissions, setting a new benchmark for sustainable photovoltaic production.

As a Mechanical Engineer (f/m/d), you will be at the interface between simulation, design, and manufacturing.

Your mission will be to convert simulation results into robust and manufacturable designs, creating functional showerhead systems for our next‑generation production tools.

Through close collaboration with process engineers, suppliers, and internal stakeholders, you will contribute directly to the advancement of Nex Wafe's groundbreaking wafer manufacturing technology.

Join our international team and help drive the transition toward a more sustainable energy future.

• Your Mission
• Mechanical Design & Equipment Development
• Initiate and evaluate solutions to optimize equipment and machinery.
• Discuss requirements with stakeholders and translate them into functional specifications and mechanical designs.
• Evaluate concepts and perform engineering calculations for new equipment and installations.
• Convert simulation results into manufacturable designs, contributing to the development of functional showerhead systems.
• Support the evaluation and implementation of concepts for digital manufacturing documentation.
• Supplier & Installation Support
• Proactively manage, support, and coordinate suppliers on‑site.
• Initiate, facilitate, and manage technical specifications for parts and assemblies used in procurement activities.
• Proactively manage, coordinate, and provide technical support for installation and assembly activities.
• Participate in technical discussions with suppliers and internal stakeholders to ensure successful project execution.

Your profile

Must-Haves

• Degree in Mechanical Engineering or a comparable engineering discipline (Bachelor's or Master's degree; Master's degree preferred).
• Minimum 3 years of full‑time industrial experience in mechanical design and engineering after graduation, preferably within semiconductor equipment, photovoltaic manufacturing, vacuum technology, process equipment, plant engineering, or metalworking industries.
• Solid knowledge of vacuum technology and its application in design, development, and commissioning.
• Practical knowledge of welding technologies and welded assemblies used in equipment construction.
• Experience with CAD software such as Inventor, Auto CAD, or similar design tools.
