The successful candidate will play a leading role in the design, coordination, and technical assurance of substation layouts and earthing systems, working closely with multidisciplinary teams, clients, contractors, and network operators.

• Lead the production of primary electrical designs for HV and EHV substations, including AIS and GIS systems up to 132kV.
• Develop earthing designs, including modelling, above-ground layouts, and site-wide earthing philosophies.
• Produce and check electrical layout drawings, including:
• Cable route layouts and sections
• Switch room and control room layouts
• Earthing and bonding layouts
• Site-wide ducting and cabling routes
• Work as part of the wider electrical design team to deliver coordinated design outputs in line with programme and quality requirements.
• Ensure all designs comply with relevant British, IEC, and utility standards, client specifications, and project requirements.
• Provide technical guidance and mentoring to junior engineers and designers within the team.
• Support tendering activities, feasibility studies, and concept design development.
• Review and approve third-party design submissions and contractor documentation where required.

Degree or HNC/HND in Electrical Engineering (Power Systems preferred).

Proven experience working within a consultancy, contractor, or utility environment in the power or renewables sector.

Demonstrable experience in the primary electrical design of HV/EHV AC substations and BoP projects, typically from 11kV to 132kV.

Strong understanding of HV and EHV substation installation practices, specifications, and industry standards.

Experience providing technical leadership or management of a specialist design team.

Competent in interpreting and producing engineering drawings and technical documentation.

Familiarity with earthing design software and modelling tools (e.g. CDEGS or similar) is desirable.

Strong communication skills with the ability to engage confidently with internal teams and external stakeholders.

Proficient in producing substation layout drawings for:

• 11kV & 22kV distribution networks
• 33kV switch rooms and control rooms
• 66kV & 132kV AIS substations
• 132kV GIS substations

Ability to model earthing systems and interpret results to inform safe and compliant designs.

Produce above-ground earthing layouts, including equipment bonding and structural connections.

Develop site-wide ducting, trenching, and cabling layouts aligned with civil and electrical interfaces.

Maintain high standards of quality, safety, and compliance across all design deliverables.
