About The Team

You'll join our Power business, which designs and builds the networks that carry energy where it's needed, including high-voltage cable routes under live highways and into operational substations. You'll report daily to the project manager and work with gangs, jointers and subcontractors, the client and DNO/IDNO representatives.

The Role

This is a hands-on site role. You'll supervise the day-to-day delivery of civil works in highways and substations, focused on ducting, cable installation and the associated jointing and substation works, keeping everything on the ground to JSM, DNO and IDNO standards, safety rules and programme.

What you'll do

• Run the works face daily briefings and toolbox talks, allocating labour, plant and materials, and supervising gangs, jointers and subcontractors
• Control permits to work, points of isolation and safe systems of work in live environments, stopping work and escalating where standards aren't met
• Inspect works as they're installed, carrying out quality checks and ITP sign-off
• Act as the site contact for the client, DNO/IDNO representatives and subcontractors, reporting progress against programme to the project manager every day
• Keep site records current: diaries, timesheets, permits, as-builts and materials and support testing, commissioning, snagging and handover

Good to know: this is a site-based role on live highways and in operational substations.

What You'll Bring

Essential

• Proven site supervision of HV cabling works up to 132kV or above, in highways and substation environments for DNOs or IDNOs
• Strong practical knowledge of ducting, cable pulling, jointing and substation civils, and experience supervising direct labour and subcontract gangs in live environments
• Experience working to permits, points of isolation and DNO/IDNO safety rules, with working knowledge of CDM and NRSWA
• Confidence working from drawings, cable schedules, method statements and risk assessments, and keeping accurate site records and daily reports
• SSSTS, SWQR Blue (Supervisor), CSCS/EUSR card, First Aid at Work and TWC/TWS certification

Nice to have

• SMSTS
• NRSWA Supervisor (Streetworks) units
• IOSH Managing Safely and confined spaces (medium risk) training

You'll thrive here if you

• Lead by example on safety and aren't afraid to challenge unsafe practice
• Make sound calls in fast-moving site situations, escalating early when needed
• Take pride in getting installation right the first time, with a sharp eye for detail
• Know that good delivery depends on civil, power and digital teams pulling in the same direction
