Neutronics Engineer
Munich
Full-time
Permanent employee
About the role
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
- 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
Competences and preferred skills
- Familiarity with HPC environments.
- Experience coupling neutronics tools with multiphysics frameworks (e.g., COMSOL, MOOSE).
- Experience with depletion, activation and shut down dose rate calculations.
- Basic knowledge in fusion related materials and components.
- Understanding of tritium transport/retention modelling on component level.
- Ability to coordinate with other engineering disciplines as part of the analysis of various components.
- Excellent problem-solving skills and attention to detail.
