Technical Director - High Voltage

Description

• Provide technical leadership, guidance, and mentoring to engineers at senior and principal level.
• Lead and deliver detailed RIBA Stage-4 HV designs up to 33 kV, including calculations, protection coordination, modelling, and technical assurance.
• Produce and review HV system documentation such as SLDs, fault studies, load flow analysis, and protection philosophies.
• Advise on private HV network connections, grid interfaces, and compliance with relevant standards and regulations.
• Support decarbonisation, electrification, and resilience upgrades across private networks.
• Shape and grow an HV engineering capability with strong organisational backing.
• Work on a diverse portfolio of private-sector decarbonisation, resilience, and HV infrastructure projects.
• Support the wider team with project delivery, technical problem-solving, and quality assurance across electrical design packages.
• Develop specifications for HV substations, switchgear, transformers, earthing systems, and associated protection schemes.
• Contribute to resilient electrical system design, including redundancy strategies (e.g., N+1, 2N architectures).
