Data Centre Jobs: The Roles in Demand 

By Kerry Ryan

ellipse-pattern
The data centre jobs most in demand in the UK right now are MEP and building services engineers, commissioning engineers and managers, HV engineers, electrical Authorised Persons and critical facilities technicians. These are the people who bring power and cooling into a building, prove that it works under pressure and keep it running around the clock. Demand is rising faster than supply: in the Uptime Institute’s 2026 global survey, 53% of operators said they struggle to find qualified candidates, up from 46% a year earlier. 
Below, the roles are grouped by project stage so you can see where your experience fits, or you can go straight to live data centre jobs. 

Growing demand 

Demand for UK data centre jobs is growing alongside the digital economy. Data centres store and process the information behind the online services we use every day, from online banking and cloud storage to business operations.  
As our reliance on these services increases, so does the need for larger facilities and skilled professionals to build, maintain and operate them. This is driving investment in hyperscale data centres, which support major cloud providers, and colocation facilities, where businesses can rent space and infrastructure rather than run their own. 

 

Design and pre-construction

The first stage of a data centre project involves planning the facility and deciding what systems and infrastructure it will need. This includes power supply, cooling, electrical systems and building layout. 
MEP and building services engineers design and plan the mechanical, electrical and public health systems. This includes power distribution, ventilation, cooling and fire protection. Most candidates come from mechanical, electrical or building services backgrounds. With more experience, they can move into senior engineering, design management and technical leadership roles. 
Planners and project controls specialists help keep projects on track. They create schedules, monitor budgets and track progress against deadlines. Experience in construction, infrastructure or engineering projects is useful, with opportunities to progress into programme management and senior project roles. 
 

Construction and MEP installation 

During construction, teams build the facility and install the electrical and mechanical systems needed to keep it running. 
Electrical and mechanical site managers oversee the installation of equipment such as generators, UPS systems, switchgear and cooling systems. They manage contractors, organise site work and make sure everything is installed correctly. Experience in MEP construction, building services or industrial projects is useful. These roles can lead to senior construction management and project leadership positions. 
HV engineers work on the high-voltage systems that supply power to data centres. This includes substations, transformers and power distribution networks. Experience in utilities, power generation or transmission and distribution is particularly relevant. 
QA/QC and HSE professionals help make sure construction work meets quality and safety standards. QA/QC specialists check installations and review project documentation, while HSE professionals manage site safety, risk assessments and compliance. Both roles offer opportunities to progress into senior quality, compliance and health and safety positions.

Testing and commissioning 

Before a data centre can open, all its electrical, mechanical and control systems need to be tested to make sure everything works properly and reliably. 
Commissioning engineers and managers plan and oversee these tests. They check equipment such as generators, UPS systems, cooling systems and power distribution. They also identify faults, check performance and make sure everything is ready before the facility opens. Experience in MEP installations, industrial facilities or critical infrastructure is useful for these roles. 
Integrated Systems Testing (IST) is another important part of the process. This involves testing how different systems work together, including how backup power and cooling respond to simulated failures. The aim is to make sure the facility can keep running if something goes wrong. 
BMS and EPMS specialists help make sure building and electrical systems work as they should. Building Management Systems (BMS) monitor and control services such as ventilation and cooling, while Electrical Power Monitoring Systems (EPMS) track power supply and distribution. Experience in building controls, automation and electrical monitoring is useful. 
With more experience, commissioning professionals can move into senior management, specialist engineering and technical consultancy roles. 

 

Operations and critical facilities 

Once a data centre is up and running, it needs to be monitored and maintained around the clock. Operations teams make sure the facility has a reliable power supply, cooling and connectivity. 
Critical facilities engineers and technicians look after the electrical and mechanical systems that keep the data centre running. This includes carrying out regular maintenance, fixing faults and monitoring equipment such as generators, UPS systems, switchgear and cooling systems. Experience in building services, industrial maintenance or other critical environments is useful. 
Data centre technicians help maintain the equipment and technology inside the facility. Depending on the role, this can include working with servers, storage equipment, cabling and network hardware, as well as monitoring systems and fixing faults. Candidates with electrical, mechanical or IT support experience can progress into senior technician, engineering and facilities management roles. 
Electrical Authorised Persons (APs) are responsible for making sure electrical work is carried out safely. They oversee procedures such as electrical isolation, switching and permits to work. Previous electrical engineering experience and the relevant authorisations are usually required. 

 

A Career in Data Centres 

You do not necessarily need previous data centre experience to build a career in the industry. Many of the skills required are transferable from construction, building services, utilities, manufacturing and other areas of critical infrastructure. Electrical and mechanical engineers, commissioning specialists and professionals from industrial projects, hospitals and airports can bring valuable experience. There are also opportunities for people from the armed forces, particularly those with experience maintaining technical equipment and working in safety-critical environments. 
ERSG places engineers, technicians and project professionals across the full data centre lifecycle, on both contract and permanent terms. If you’re weighing up the two, read our guide to contract vs permanent data centre jobs, or explore our data centre recruitment work.
