Senior Simulation Engineer, Computational Physics

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.

Alpha will be the first stellarator to demonstrate net energy. Achieving this milestone requires building a deeply coupled machine, where plasma, magnets, structures, cryogenics, and heating work at the edge of each discipline’s capability. You will own a selected set of the models, stretching over domains, e.g. microwave physics to plasma radiation.These models will be used by the design team to compute load cases, assess system-level tradeoffs, perform numerical optimization, and simulate the whole machine as a single system. You will own these models end-to-end, from definitions of inputs and outputs, to implementation correctness, and software efficiency.

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.
