Infinity Two stellarator power plant and future commercial systems. Responsibilities Develop and execute a comprehensive roadmap for MOOSE‐based modelling, including physics capability development, validation strategy, and integration with the broader design toolchain. Lead the development of tightly coupled multiphysics models (thermal, structural, tritium transport, radiation, electromagnetics, and materials … behaviour) to support fusion energy system design. Establish best practices for software quality assurance, model development, verification & validation (V&V), configuration control, and reproducibility. Collaborate with cross‐functional teams (plasma physics, neutronics, mechanical, thermofluid, materials, systems engineering) to ensure consistent and integrated modelling approaches. Develop workflows to couple ...
