WHO WE ARE
Proxima Fusion is Europe’s fastest-growing fusion company and the continent’s best-funded fusion player, as well as the first spin-out from the Max Planck Institute for Plasma Physics (IPP). Backed by over €650M and powered by a growing team across Munich, Zurich, and Oxford, we are developing the hardware and infrastructure needed to deliver the world’s first commercial stellarator fusion power plant.
Our concept advances the most mature fusion technology out there, the Wendelstein 7-X stellarator, through two next-generation machines: Alpha and Stellaris. Our work combines stellarator optimization, advanced computation, machine learning, and high-temperature superconducting magnets to unlock higher-performance designs that were previously out of reach.
Turning these designs into a functioning fusion power plant requires excellence and ownership across every discipline, from physics and engineering to software, manufacturing, law, and business functions.
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.
WHY JOIN PROXIMA FUSION
You will get to work on some of the most complex tech challenges to bring abundant, safe, clean energy to the world.
You'll get to join and learn from an exceptional selection of accomplished and driven individuals.
Do your life’s best work and enjoy the journey.
Get to show that big things are possible in Europe when you assemble the best talent.
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
INTERVIEW PROCESS
Recruiter Interview (30-60 min)
Technical Screening (30 min)
Technical Panel (2x60 min)
Practical On-site
*This role sits at L2 of our framework, please inquire during the recruitment process for further information.
At Proxima Fusion, our mission is bold: making limitless clean energy a reality. To get there, we need a high-performing, diverse team that brings different perspectives, challenges assumptions, and builds together with purpose. We know that diversity of thought and experience leads to better ideas, stronger execution, and a more resilient team. We don’t look at how you identify, what you look like, who you choose to worship or what ethnicity you are. We care about what you can bring to the table.
