Technical Director – High Voltage (HV) Engineering
Salary: £80,000 – £100,000
Location: Fully flexible across the UK
Security: SC Clearance (or ability to obtain) essential
Overview
An established engineering consultancy is seeking a High Voltage (HV) Technical Director / Associate Director to lead and strengthen their HV design capability. This hire represents a strategic opportunity to bring in a technically strong leader who can provide hands-on delivery support and guidance to an existing team of engineers.
This role is ideal for someone who is technically exceptional, enjoys complex design delivery, and wants to support and mentor a growing HV engineering function—without the pressure of work-winning or BD targets.
The team works almost exclusively on private-sector projects, delivering a wide range of electrical infrastructure solutions across industries including healthcare, industrial facilities, renewable energy, energy transition, and mission-critical estates.
Key Responsibilities
* 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.
* Carry out HV network modelling and analysis using ETAP (essential).
* Provide technical leadership, guidance, and mentoring to engineers at senior and principal level.
* 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).
* Advise on private HV network connections, grid interfaces, and compliance with relevant standards and regulations.
* Support decarbonisation, electrification, and resilience upgrades across private networks.
Note: This is a delivery and technical leadership role—no expectation for business development or bringing in work although it would be a bonus.
Role Requirements
* Chartered Engineer (CEng) – mandatory.
* Extensive experience in HV design up to 33 kV, with strong technical capability at detailed design (RIBA Stage-4).
* Proficiency with ETAP for modelling, coordination, and system studies – essential.
* Strong experience producing calculations, performing protection studies, fault analysis, load flow studies, and earthing design.
* Demonstrable ability to deliver complex HV projects independently while supporting and guiding a team.
* Experience working within private networks, such as:
* Healthcare estates decarbonisation
* Onshore/offshore wind connections
* Industrial facilities
* Private HV/LV network upgrades
* Eligibility for SC Clearance (or existing clearance) – essential.
* Could suit a current Associate, Associate Director, or Technical Director seeking progression or a more delivery-focused leadership role.
The Opportunity
* Join at a pivotal moment, filling a critical technical gap in the team.
* 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.
* Flexible UK-wide working—no location constraints.
* Future opportunity to influence recruitment of Seniors and Principals once the technical lead is in post.
