## Description

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 Shape the architecture of the world’s first commercial fusion power plant – Own system-level decisions that determine how a first-of-a-kind energy technology is designed, integrated, and ultimately deployed at scale. Solve some of the most complex engineering challenges in industry – Work across tightly coupled disciplines (plasma physics, magnets, cryogenics, manufacturing, controls, and more) to resolve critical trade-offs and turn cutting-edge science into a functioning product. Build real hardware with a pragmatic, fast-moving team from all over the world – Combine advanced simulation and systems thinking with a strong execution mindset, focusing on practical engineering solutions that accelerate the path to commercial fusion energy. 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 make Proxima's plasma simulation stack trustworthy by confronting it with reality. Every prediction we make for Alpha – Proxima's Q>1 experimental stellarator – and for Stellaris, our commercial power plant, rests on models whose credibility has to be earned against real measurements from an operating device. W7-X is where we earn it. You will take our integrated modeling framework, FUS3, and our Bayesian plasma state estimation workflow to W7-X data: reconstruct the plasma state from diagnostic measurements, compare our predictive models against what the machine actually did, and turn the discrepancies into a prioritized map of where our physics is right, where it is not, and what we must fix before Alpha's first plasma. Modeling sits on Alpha's operational critical path and cannot be backfilled after first plasma – this role is how we get ahead of it. You will be the person in the group who lives at the intersection of modeling and experiment: fluent enough in the physics to know what a model should predict, and close enough to the diagnostics to know what the data can actually support. WHAT YOU WILL DO Validate Proxima's predictive plasma models against W7-X experimental data – neoclassical and turbulent transport, 3D equilibrium, ECRH deposition, pellet fueling and drift, bootstrap current and iota evolution – and record each comparison as a reproducible validation report with quantitative agreement metrics, stated limitations, and a pinned regression test Reconstruct the plasma state from real diagnostic measurements using our time-dependent Bayesian state-estimation workflow (Thomson scattering, interferometry, CXRS, ECE, XICS, bolometry, magnetics), with calibrated uncertainties, and benchmark it against established analyses such as Minerva/IDA reconstructions and ASTRA power-balance results Work with raw and pre-processed
