A specialist data centre engineering and infrastructure business is seeking Cable Technicians / Data Centre Installers to support the delivery of connectivity infrastructure for hyperscale cloud providers, colocation operators and enterprise customers. The organisation provides services spanning mechanical and electrical engineering, structured connectivity, bespoke manufacturing, containment, electronic security and facilities services, supporting clients from design and construction through to commissioning and operation.

The wider group has approximately 1,000 people, active projects in 16 countries and a customer base that includes four of the five largest hyperscalers and more than 25 colocation providers. Following an October 2026 merger and new investment, the business has expanded its liquid cooling and high-density infrastructure expertise and forecasts revenue above US$400 million for 2026. Its growth plans include recruiting 200 engineers over the following 12 months and opening facilities in Europe and North America.

Role Overview

Based within a hands-on installation team in London data centres, the Cable Technician / Data Centre Installer will install, terminate, test and maintain copper and fibre connectivity infrastructure. Working from drawings, cable schedules and agreed project scopes, you will deliver consistent, high-quality installations and support the wider team in meeting programme, safety and client requirements.

The role offers a salary of £37,000 - £45,000, a van and overtime paid at 1.5 times the standard rate, with the opportunity to work in demanding data centre environments. Experience on AI and hyperscale installations would be a major advantage.

Key Responsibilities

• Install, terminate and patch copper and fibre cabling in line with drawings, cable schedules, manufacturer requirements and the agreed project scope.
• Carry out structured cabling tests using suitable equipment, including Fluke analysers, checking the correct test setup and recording results accurately.
• Identify and rectify installation faults, investigating failed tests and reporting any issue that requires engineering input or a change to the agreed design.
• Support containment, rack and associated infrastructure installation, coordinating your work with other trades and maintaining safe access to the work area.
• Follow cable-management requirements, including routing, bend radius, identification and labelling, so installations are consistent, maintainable and ready for client inspection.
• Keep test records, marked-up drawings and installation schedules current, providing supervisors with reliable information for progress reporting and handover documentation.
• Check deliveries and materials, report shortages or damage and help maintain control of tools, equipment and stock allocated to the job.
• Work safely within site rules and agreed working methods, including controls for access equipment, working at height and protecting adjacent installations.
• Communicate professionally with supervisors and client representatives, escalating site issues early and helping the team meet quality and programme expectations.
• Work flexibly across project sites and support overtime where required to meet project delivery needs.

About You

We are looking for a Cable Technician / Data Centre Installer with:

• At least two years' experience installing, terminating and testing structured cabling, including copper and fibre systems within data centre environments.
• Practical experience with recognised cabling systems such as Corning, CommScope, Panduit, Brand-Rex, Excel or equivalent manufacturers.
• Confidence setting up and operating Fluke analysers, understanding test results and locating and rectifying faults in installed cabling.
• A structured cabling or IT networking qualification such as NVQ Level 3 or equivalent; relevant manufacturer training or CNCI certification would be advantageous.
• The ability to work from drawings and cable schedules with limited supervision, while knowing when to ask for clarification or escalate an issue.
• A current CSCS card. IPAF or PASMA training would be useful for the access requirements of installation work.
• A full driving licence, willingness to travel between project sites and flexibility to support overtime where project requirements call for it.
• A reliable, quality-focused approach, good customer-facing communication and willingness to complete the required site security and background checks.
• AI or hyperscale data centre installation experience is particularly valuable; experience supporting high-density deployments will help you stand out.
