Proxima Fusion Tech Stack

Stellarator fusion reactor developer scaling toward commercial power generation

Electric Power Generation Munich, Bavaria 51–200 employees Founded 2023 Privately Held

Proxima Fusion is building stellarator fusion reactors with a hardware-first engineering organization: 36 engineers across materials, magnets, cryogenics, and civil systems, supported by ops, finance, and research teams. The tech stack—Python, C++, Fortran, Kubernetes, Ray, Dask—reflects computational intensity (physics simulation, optimization across hyperparameter spaces) paired with infrastructure for real-time test instrumentation. Active ERP adoption (Coupa, SAP, Oracle) signals scaling from R&D into manufacturing and supply-chain operations, a critical inflection for stellarator commercialization.

About Proxima Fusion

Proxima Fusion designs and builds stellarator fusion power plants, a tokamak alternative offering inherent stability advantages for commercial deployment. Founded in 2023 and based in Munich, the company is executing toward an alpha demonstrator—a full-scale prototype reactor—with parallel work on materials qualification, magnet prototyping, cryogenic systems, and civil/structural infrastructure. The organization spans engineering (materials science, magnets, systems integration), operations (manufacturing readiness, supply chain), finance, and research. Projects span coil design, materials selection and verification, equipment procurement and rollout, and real-time test dashboards. Hiring is active across Germany, the UK, and Switzerland, targeting mid- and senior-level engineering talent to execute the alpha build and scale manufacturability.
