Senior Radiation Physicist

Our team designs and validates radiation shielding for the UK's nuclear submarine fleet across three major programmes. We handle shield design, build assessments, metrology, and safety studies, while developing novel detectors and electronics capability. We offer relocation support packages across all Submarines roles, subject to meeting eligibility criteria.
