Head of Commissioning
Join JSM Group to design and install power, digital, and specialist networks that keep critical industries running — grow your skills, impact, and career with us.
THE ROLE
You’re the last line before the lights go on.
As Head of Commissioning, you’ll own commissioning on extra-high-voltage substations and underground cable circuits from 11kV to 400kV. You’re the technical authority and single point of accountability across multiple projects in data centres, renewables and industrial & commercial connections.
You’ll lead a team of commissioning engineers, shape the commissioning plan from design through to handover, and deliver systems that are safe, on programme and ready for energisation.
WHAT YOU’LL DO
• Own it. Lead commissioning across multiple new connection and infrastructure projects, from design development to final handover.
• Plan it. Define the commissioning strategy for 11kV to 400kV projects and build plans that fit within the project programme.
• Back it. Be the senior technical authority, resolve on-site issues, and be the first call for internal teams, clients, and network operators.
• Grow the team. Set objectives, manage performance and build development pathways for your commissioning engineers.
• Keep it safe. Hold subcontractors and supply chain partners to our SHEQ procedures, the Distribution Safety Rules and CDM regulations.
• Join it up. Support FAT and SAT, work with the Engineering Standards team, and give technical input to bids and tenders.
WHAT YOU’LL BRING
• Proven leadership of commissioning engineers at a DNO, TSO or ICP in the UK.
• At least 5 years as a Senior Authorised Person or Commissioning Engineer on 11kV to 132kV in the UK. 400kV and transmission-connected experience is a bonus.
• Deep technical knowledge of HV plant and switchgear, substation design, cable systems, civil engineering, and protection & control.
• Strong grasp of the Distribution Safety Rules, DNO G81 standards and the NERS scheme.
• HNC in Electrical or Civil Engineering, or equivalent.
• Experience supporting tendering, estimating and work-winning.
• Sharp analytical skills, clear communication and a team-first approach. Full UK driving licence and willingness to travel.
