Microwave Design Engineer

<p style="min-height:1.5em"><strong>WHO WE ARE</strong> </p><p style="min-height:1.5em">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.</p><p style="min-height:1.5em">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.</p><p style="min-height:1.5em">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.</p><div style="min-height:1.2em;margin-top:0px;margin-bottom:0px"> </div><p style="min-height:1.5em"><strong>WHY JOIN PROXIMA FUSION</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Work on a civilisation-scale problem </strong>- Clean, baseload fusion energy is one of the few genuinely world-changing challenges, and every hire in Finance, People, or Legal directly accelerates the path to a working stellarator.</p></li><li><p style="min-height:1.5em"><strong>Grow as fast as the company does</strong> - With headcount set to roughly 5x in a few years and major technical milestones ahead on the path to our demo machine and first power plant, your role grows under you; today's hire is tomorrow's function lead.</p></li><li><p style="min-height:1.5em"><strong>Tackle problems that don't exist elsewhere</strong> - Fusion sits at a rare intersection of deep-tech R&amp;D, industrial procurement, government relations, and venture financing, so non-tech functions face challenges no other workplace can offer.</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>YOUR IMPACT</strong></p><p style="min-height:1.5em">As a microwave design engineer, you will help build the basis for the millimeter wave hardware acting as the spark plug that initiates a fusion plasma and raises its temperature to greater than 100 million degrees. You’ll join the Alpha Heating System team ready to drive the integrated RF and thermo-mechanical design of high-power components, and help build and test these components in the lab before installing them at scale on our net scientific gain Alpha stellarator.</p><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>WHAT YOU WILL DO</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Provide innovative solutions to complex RF engineering challenges by collaborating closely with physicists to ensure component designs meet the Alpha plasma physics and thermal-mechanical constraints.</p></li><li><p style="min-height:1.5em">Develop designs and evaluate vendor designs to determine an optimal path to efficiently deliver our power to the stellarator - driving down the denominator of input power that will limit fusion power plant gain Q=Pout/Pin - and drive down costs.</p></li><li><p style="min-he
