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.

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

• Shape the future of Proxima’s simulation platform: we design and develop the platform; stellarator researchers and engineers use it to mature the design of Alpha and Stellaris; you will imagine and build with us novel solutions for simulation tools that spark joy and reduce time-to-insight

• Accelerate Stellarator R&D, at the company at its forefront: we work side by side with researchers and engineers to ensure what we build immediately boosts the speed Proxima Fusion’s Stellarator design program

WHAT YOU WILL DO

• The Simulation Platform Team balances development of core products and direct support to researchers, adapting to the Stellarator design program’s strategy and priorities.

  • On the platform engineering side you will design, develop and maintain next-generation software solutions for stellarator simulation and design, targeted to human and agentic use: our team manages the full platform from Python libraries enabling automation of large-scale simulation workflows, to cloud-based data storage that keeps everyone in sync, to web applications that foster cross-domain collaboration and knowledge discovery, including integration of AI tools where they actually provide leverage
