We are seeking a highly skilled and motivated Senior Level Electrical Engineer to join our high‑voltage renewables engineering team. The successful candidate will be responsible for providing high quality earthing designs and electrical substation layouts. This role is critical to ensuring the safe, reliable, and efficient operation of our clients electrical networks.

• A Degree/HND/HNC in Electrical Engineering (Power Systems Electrical preferred).
• Previous experience with consultancy, contractor or utility in the Power industry.
• Previous experience of technical management of a specialist design team.
• Experience in the field of primary electrical design of HV / EHV AC substations and BoP projects ranging from 11kV to 132kV.
• Understanding of industry HV and EHV substation installation standards and specifications.
• Ability to take the initiative, demonstrate a pro‑active approach to activities, problems and oneself.
• Understanding of power cable installation, their requirements and installation parameters i.e. flexible or rigid arrangements, minimum bending radii etc.
• Ability to manage the various inter‑departmental design interfaces (i.e. structural design, planning, electrical design, CAD technicians) efficiently and effectively to deliver complex designs solutions.
• Ability to both write and understand technical documents relating to all aspects of substation electrical plant & equipment.
• Have an excellent understanding of risks associated with cabling works. Have working knowledge of the role of the designer under the CDM Regulations 2015.
• Ability to complete a designer's risk assessment for designs being developed and produced.
• Ability to prioritise workloads in a proactive and organised fashion (using software tools as necessary) to ensure key deadlines are met and reliant parties are kept informed.
• The ability to use a proprietary 3D CAD package such as Revit would be desirable.

• Be proficient in producing substation electrical layout drawings for
• 11kV distribution networks
• 22kV distribution networks
• 33kV switch rooms and control rooms
• 66kV AIS substations
• 132kV AIS substations
• 132kV GIS substations
• BoP/EPC site layouts for battery and other renewable projects
• Produce plan and elevation drawings through HV / EHV AIS compounds.
• Produce bus bar calculations to determine the most appropriate busbar size and support requirements.
• Produce busbar bar and clamp schedules, specifying the correct fixed and sliding clamps for the installation situation.
• Produce initial outline support structure designs and schedules, allowing a specialist steel fabrication provider to detail up.
• Design and analysis of earthing systems for substations, power plants, renewable energy sites (e.g., solar, wind, battery), and grid connections.
• Act as the named earthing design engineer for a particular project. This typically involves producing a suite of earthing design drawings and documents.
• Modelling of earthing systems within CDEGS (typically we would expect our primary electrical designers to provide a base earthing layout).
• Perform soil resistivity testing, earth potential rise (EPR) studies, and touch/step voltage assessments.
• Familiarity with electromagnetic compatibility (EMC) and lightning protection.
• Undertaking fall of potential testing where necessary.
• Production of a final earthing fall of potential test report.
• Undertaking impressed voltage studies and producing associated technical reports.
• Undertaking lightning risk assessments and lightning studies (if the risk assessment process determines a requirement).
• Specification of earthing materials for above and below ground earthing and lightning protection systems.
• Where necessary, manage external design suppliers who may be undertaking earthing design or similar activities.
• Undertake lightning risk assessments to the requirements of BS 62305-2.
• Produce above ground earthing layouts to communicate to site installation teams how to connect…
