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.
