THE COMPANY
Established in 1998, JSM Group is a leading specialist infrastructure engineering company. We design and install the complex power networks, digital infrastructure and specialist systems a future-focused worldwide marketplace needs.
From High-Power grid connections to Critical Utilities. Data Centres to Renewable Energy, our full turnkey solution teams manage the full scope to help advise and deliver complex infrastructure projects at speed, on time and with reduced legislation, technical and commercial risks.
THE TEAM
Join the Power Operations team at JSM Group Services Ltd., a leading provider of integrated utility infrastructure solutions. Our combination of end-to-end technical expertise, decades of industry experience, and unlimited fresh thinking makes us a trusted partner in delivering next-generation connectivity in energy and communications across the UK, Europe, and beyond.
Our Power team delivers high-value electrical infrastructure projects for some of the most demanding clients in the sector – from hyperscale data centre operators to major industrial and grid clients. We are building a team of exceptional project management professionals who can drive complex programmes from award through to energisation, and we want people who take real ownership of their projects.
SCOPE OF ROLE
You will supervise the day-to-day delivery of civil works within Highways and within substations, with a strong focus on ducting and cable installation and the associated jointing and substation works. You will keep every activity on the ground in line with JSM/IDNO/DNO standards, safety rules and programme requirements.
This is a hands-on site role. You will run the works face — briefing gangs and subcontractors, controlling permits and points of isolation, checking quality as it is installed, and reporting progress to the project manager every day.
