1851 Job Purpose / Overview The Commissioning Team is expanding in preparation for the commissioning of the first nuclear power station to be built in a generation. As a company that foster an inclusive culture, valuing the unique strengths, perspectives, and experiences of all employees, we are seeking talent from diverse backgrounds and level of expertise. The Senior Electrical Commissioning Engineer is responsible for leading, executing, and assuring commissioning activities for LV, HV, and EHV electrical systems. The role ensures that electrical systems are safely energised, validated against design intent, and demonstrated compliant with nuclear safety, environmental, and industrial standards. In doing so, the role supports the Commissioning Arrangements and contributes directly to fuel-load readiness and system handover to operations. Principal Accountabilities Plan and coordinate electrical commissioning activities by developing commissioning test plans, reviewing schedules, confirming resource and equipment availability, and ensuring the latest revisions of commissioning instructions are in use. Execute and oversee the commissioning of LV, HV, and EHV electrical systems including switchboards, transformers, batteries, UPS, protection relays, interlocks, and EHV grid-interface equipment up to 400 kV. Apply and enforce nuclear, electrical, and industrial safety requirements, including pre-job briefs, point-of-work risk assessments, and surveillance of safety rule compliance. Implement configuration control by reviewing and validating redline mark-ups, managing temporary modifications, and ensuring commissioning data is accurately captured in IT systems (e.g., EAM, Switch, CMS). Analyse and verify electrical commissioning results, assessing compliance with acceptance criteria, identifying deviations, and engaging designers or vendors for technical resolution. Manage governance activities including control of commissioning hold points, ensuring tests meet nuclear safety justification requirements, and providing traceable LC-6 evidence packages. Coordinate multi-discipline interfaces by supporting mechanical, I&C, and process commissioning teams on systems containing electrical interactions or safety dependencies. Lead system walkdowns and acceptance by verifying system completeness, reviewing handover documentation, closing punch-list items, and confirming readiness for testing or energisation. Capture, record, and communicate OPEX (operational experience) to support continuous improvement across commissioning activities. Mentor and guide junior engineers and technicians, promoting nuclear professionalism and developing commissioning capability within the programme.

Strong technical knowledge of HV/EHV/LV electrical distribution systems, grid-interface equipment, protection, UPS, DC systems, and control systems. Significant experience in commissioning within highly regulated sectors (nuclear, power generation, transmission, or oil & gas). Demonstrated competence in protection relay testing, logic and interlock verification, and safe HV/EHV energisation planning. Understanding of nuclear safety culture, regulatory expectations, and configuration management. Ability to interpret complex electrical drawings (SLDs, wiring diagrams, logic diagrams). Experience working under electrical safety rules, PTW, LOTO, and statutory regulations (HASAWA 1974, Electricity at Work Regulations 1989). Strong communication, analytical, and problem-solving skills. Desirable Experience with nuclear plant systems commissioning, operations, or maintenance. Experience with EPR (NNB) electrical system architecture. Chartered Engineer or working toward professional accreditation. Experience in FAT oversight, supplier engagement, and specialist testing. Technical Competencies Expert understanding of HV/EHV/LV electrical systems, grid protection, and switching operations. Competent in electrical testing technologies (relay test sets, insulation testing, secondary injection, logic verification). Skilled in diagnosing complex power system faults during commissioning phases. Strong ability to produce technical justifications, test reports, and commissioning evidence packages. Familiarity with commissioning IT systems for configuration, defect management, and validation. Effective project management and stakeholder communication are crucial for coordinating activities and delivering successful projects. Continuous learning and collaboration with multidisciplinary teams ensure stays updated with advancements and meets client requirements.
