About this role
As a Mechanical Engineer , you will join Derby/ Warrington/ Manchester team to support our activities within the Nuclear sector.
You will contribute to high-integrity engineering assessments involving blast loading, fire response, and extreme structural events, working on complex systems where engineering judgement is required beyond standard design codes. The role combines analytical hand calculations with advanced numerical modelling to support design assurance in regulated environments.
You will collaborate with multi-disciplinary teams to evaluate equipment response, verify load paths, and develop robust engineering methodologies for challenging scenarios.
