Neutronics Engineer at Gauss Fusion GmbH

About the role

Main responsibilities

• 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
• Work within a highly collaborative, multidisciplinary team tackling challenges with no established blueprint, requiring creativity, persistence, and systems thinking.

Qualification and educational requirements

• Master’s degree or higher in nuclear engineering, nuclear and/or particle physics, astroparticle physics, fusion engineering or related field.
• Strong understanding of nuclear physics with a focus on interaction of fast neutrons with matter
• High proficiency with Monte Carlo neutronics tools such as OpenMC and MCNP or PHITS
• Demonstrated experience with advanced neutronics workflows (e.g., large-scale CSG models, DAGMC, CAD to CSG conversion, unstructured mesh) and application of variance reduction methods (e.g., weight windows)
• Experience with advanced data reduction and processing (NumPy, Pandas, Matplotlib, SciPy)
• Experience with working in Linux operating systems
• Proficiency in 3D CAD modelling tools (e.g. FreeCAD)
• Proficiency in 3-D meshing of CAD models
