Junior Thermal & System Engineer - Liquid Cooling Solutions

We are pioneering metal foam-based cooling solutions for AI‑servers and more. Our materials are integrated into cooling solutions for both single and two‑phase direct‑to‑chip liquid cooling – enabling better performance, hotspot management, and energy savings.

Our team is built on curiosity, collaboration, and a shared drive to craft a sustainable future – while having fun along the way! Our offices are close to the train station in Baden and fully stocked with coffee and cake.

• Design prototypes and build test setups for validation of cooling performance and reliability
• Conduct hands‑on testing of prototypes, analysing experimental data to improve designs
• Design optimisation of cooling solutions and customization for different hardware
• Support customer co‑development projects across the board
• Contribute to R&D and innovation in sustainable cooling technologies

• A bachelor’s or master’s degree in engineering (e.g., Electrical, Mechanical)
