Senior Software Engineer (Dev Platform)

We're building the world's first commercial stellarator fusion power plant. First spin-out from the Max Planck Institute for Plasma Physics, based on Wendelstein 7-X (the largest stellarator ever built), €650M+ raised, teams in Munich, Zurich and Oxford. Finding a good stellarator design means searching an enormous high-dimensional space, and every candidate design needs heavy plasma physics simulation. That's the compute problem this role owns: cloud + HPC clusters, K8s, Ray, Dask, and the platform work around it (CI/CD, IaC, observability). You'd sit directly next to the physicists and AI researchers burning through that compute, so you see exactly what your infrastructure unlocks. Python and Linux. If you've wanted to point your platform engineering skills at something that actually matters, clean, abundant energy, this is about as direct a shot as it gets, and it's happening in Europe. Interview process: recruiter call, meet the team lead, technical panel, meet the CEO. https://jobs.ashbyhq.com/proxima-fusion/5aebfef0-0c2c-4c87-9...
