Zürich, Switzerland

TEAM AND ROLE

Architect a breakthrough energy technology – Play a defining role in designing and integrating the systems that will power the world’s first commercial stellarator fusion plant, influencing decisions that shape the future of clean energy.

Solve some of the most complex engineering challenges in fusion – Work across magnet design, HTS technology, manufacturing, structural integration, and controls, turning cutting-edge science into real hardware

Move fast and build what matters – Join a highly ambitious, multidisciplinary team that combines cutting-edge simulation with hands-on engineering, turning bold ideas into real hardware on the path to commercial fusion.

YOUR IMPACT

You will contribute to the development of joint and cable technologies for Proxima’s magnet programme, with a strong focus on hands-on prototyping, manufacturing, and testing at our labs based in Villigen and Böttstein.

You will play a key role in the design, fabrication, and iterative improvement of joints, cables, and other related components for magnet prototypes and future HTS magnets.

You will operate at the interface between mechanical, electrical, and experimental domains, contributing to rapid prototyping cycles and integration of components into experimental setups.

WHAT YOU WILL DO

• Design and develop mechanical and electro-mechanical components related to joint and busbar systems;
• Design and implement early concepts of superconducting cables;
• Build, assemble, and test prototypes in close collaboration with the workshop;
• Support manufacturing and integration of components into magnet prototypes and experimental setups;
• Iterate on designs based on test results, measurements, and experimental feedback;
• Contribute to the development of manufacturing processes and tooling for joint fabrication;
• Participate in experimental activities, including setup, instrumentation, and data acquisition;
• Collaborate with engineers and technicians across mechanical, electrical, and materials domains.

WHO YOU ARE

• Degree in Mechanical Engineering, Mechatronics, Electrical Engineering, or related field;
• Strong hands-on experience in prototyping, manufacturing, or experimental work;
• Experience with CAD tools (ideally CATIA; experience with NX, SolidWorks, or Onshape also relevant);
• Good understanding of electrical or electromagnetic systems (e.g. current flow, resistive losses, basic circuit behavior);
• Comfortable working in a workshop and laboratory environment;
• Pragmatic, solution-oriented mindset with ability to iterate quickly;
• Strong team player, able to work across disciplines.

NICE TO HAVE

• Experience with electromechanical systems, sensors, or instrumentation;
• Familiarity with manufacturing processes (machining, assembly, soldering, etc.);
• Experience in R&D or prototype development environments;
• Exposure to thermal, electrical, or materials characterization.
