Neutronics Engineer

In this role, you contribute to the neutronics analysis that underpins licensing and safety for the Alpha stellarator. You will develop reproducible simulations and automate neutronics workflows, leveraging a cross-functional team of ML experts, software engineers, and physicists. You’ll work with CAD/CSG models to support design and validation, helping translate cutting-edge science into a functioning, scalable fusion asset. This is a chance to shape the safety-critical foundation of the world’s first commercial stellarator power plant, at a fast-growing European fusion company.

• Perform neutronics analysis using OpenMC and DAGMC for neutron and photon responses relevant to stellarator design
• Automate neutronics workflows and integrate analyses into pipelines using Python, Git/Graphite, in a Docker environment
• Verify/validate results by comparison with other codes and experimental data
• Create simulation-ready CAD with CadQuery and CSG geometries of the stellarator and surrounding facility
• Contribute to open-source codes for nuclear data processing, CAD conversion/meshing, and particle transport simulations

• PhD or Master’s degree in nuclear physics, nuclear engineering, or equivalent experience
• Experience in processing nuclear data
• Experience with OpenMC, DAGMC, CadQuery, Gmsh for neutronics analysis
• Experience in designing neutron and gamma shielding
• Experienced Python programmer with Git
• Experience with cloud or HPC numerical simulations (desirable)

• Cross-functional collaboration
• Strong problem solving
• Good communication
• OpenMC
• DAGMC
• CadQuery
