Job description

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.
