Descrição da oferta de emprego

Gauss Fusion GmbH is advancing a commercially scalable stellarator fusion power. Our team brings together leading expertise in fusion physics, advanced engineering, computations, and industrial manufacturing. We are now seeking aNuclear & Neutronics Engineer to help shape the design, safety, and performance of our core fusion systems.
This is an opportunity to work at the frontier of fusion energy, developing critical components for a future stellarator based fusion power plant, while contributing to Europe’s most ambitious energy initiative right now!

Main responsibilities

As a Nuclear & Neutronics Engineer at Gauss Fusion GmbH, you will:

• Develop technologies for breeding blankets, first-wall structures, shielding, divertor systems, and other auxiliary components, with a strong focus on commercialization, industrialization, and engineering readiness.
• Perform detailed neutronics analyses for stellarator fusion systems, including complex CAD geometries and volumetric plasma neutron sources.
• Design, run, and optimize Monte Carlo simulations, and clearly present results to technical and non-technical stakeholders.
• Scale and refine neutronics simulations for high-performance computing (HPC) environments.
• Collaborate closely with thermal, mechanical, and materials engineers to support coupled multiphysics analyses
• Python scripting/automation to support and document simulation workflows with the use of e.g. Jupyter Notebooks
