Neutronics Engineer

We are expanding our engineering team and are seeking a Neutronics Engineer to support advanced reactor and fusion programmes. Working in multidisciplinary teams, you will ensure neutronics analysis meaningfully informs design decisions and programme strategy.

Responsibilities

• Perform Monte Carlo neutronics analyses using tools such as OpenMC for neutron and photon responses relevant to fusion device optimisation and design, comprising facility and component‑level assessments including depletion, activation, shielding and criticality.
• Construct simulation‑ready geometry models, including CSG and CAD‑based representations.
• Lead verification and validation (V&V) of neutronics analyses through comparison with benchmark problems, experimental data, and independent codes, whilst also promoting software development best practices and version control (using Git) within the company.
• Integrate neutronics workflows into automate...
