Bridging the Skills Gap in Data Centre Teams: Training, Retention, and Change
Thu 18 Sep 2025
As the pressure to secure talent for the next stage of data centre development increases, companies are increasingly looking for new ways to bridge the skills gap in data centre teams.
Skilled, experienced data centre employees have been in short supply for years, with no end in sight. In fact, a report from the Uptime Institute shows that today, more than half of data centre companies are having difficulty hiring top talent, and 42% are struggling to retain the employees they have in the face of a data centre talent war.
As Dr Glen Duncan, Data Centre Research Director for JLL, said, “Data centres are a subset of the perennial skills shortage in the information technology hardware and software space, and the digital economy.”
A number of intersecting forces have widened the gap between what data centre teams currently can do and what modern infrastructure demands.
Rapid Growth & Evolving Technology
Globally, the data centre market size is growing very rapidly. The total data centre market size of $187 billion in 2020 is projected to grow to £378.6 billion ($517.17 billion) by 2030.
With demand for data storage, processing and connectivity skyrocketing, especially in AI and machine learning, data centres require new skills in cloud architecture, automation, advanced monitoring, cybersecurity, and power/thermal management under stress. Roles once considered niche or specialist are now increasingly becoming core competencies for data centre employees.
Retiring Workforce and Lack of Fresh Pipelines
Many experienced data centre technicians, engineers, and operations leads are nearing retirement, and the supply of early-career professionals with domain-relevant experience is thin. According to DataX Connect, around 19% of data centre professionals in the UK are over age 55; in the U.S., the comparable figure is about 16%—a signal that many roles will need to be filled or the responsibility offloaded in the coming years.
Mismatch Between What Education Delivers and What Operations Require
Universities and technical institutes are struggling to keep curricula current with fast-shifting technology and operational requirements. In many cases, graduates lack hands-on exposure to the sort of “mission-critical” work that data centres demand.
Retention & Culture Issues
Even when people are hired, retaining them is a challenge. High work demands, risk of burnout, unclear career advancement, low visibility of data centre work as a career path, and competition from cloud and software firms all pull talent away. A recent survey found that many workers didn’t renew certifications, citing lack of time, lack of employer support, or no budget for development; in addition, many said management did not see “a tangible benefit” to training.
These changes, affecting the global data centre market, have resulted in increased demand for skilled professionals, and data centre owners/operators find themselves in fierce competition in a limited talent pool.
What Are Data Centre Companies Doing to Bridge the Gap?
Amid these pressures, some data centre operators and ecosystem partners are taking concrete steps to bridge the gap. Their strategies cluster around training/upskilling, improving retention through culture and incentives, and structural change to how teams are built and how knowledge is shared.
Training & Upskilling
One of the most immediate levers is enhancing internal training programs and forming partnerships with educational institutions.
Academic and Technical Partnerships.
In several countries, data centre companies are working with universities, technical colleges, and vocational schools to build curricula that reflect real operational demands. Many data centre and cloud companies have partnered with universities to develop training courses. For example, the University Technical College of Heathrow created a program to equip the next generation of data centre employees with the skills necessary for technical careers. By partnering with industry leaders, including AWS, CyrusOne, ARK Data Centres, and Yondr, they aim to provide a clear path into data centre employment by enhancing STEM skills for 14-19-year-olds and increasing awareness of the diverse careers available in the sector.
Certification & Continuous Learning.
The Uptime Institute, among others, offers accredited courses across design, operations, and management domains. These help codify skills such as Tiered operations or facility management. By supporting, reimbursing, or encouraging employees to take part in these certifications, data centre companies are helping to retain employees and reinforce the new skills that are required in the fast-changing data centre industry.
On-the-job Experiential Learning.
Apprenticeships, internships, or trainee programs help new hires gain first-hand experience. Also, cross-training staff so that people in one operational role can learn adjacent domains (e.g. mechanical to electrical, or operations to monitoring) helps widen the available internal talent pool.
Retention & Culture
Even with training, losing people undermines continuity, morale, and institutional knowledge. For many teams, culture, engagement, and purpose are as important as pay. Some companies focus on creating clear career paths for employees, which helps to keep them invested and looking forward to the future.
Another important factor is work-life balance and psychological safety. On one hand, ensuring that teams have viable working schedules, vacations, and time at home helps to reduce burnout, which improves retention. Additionally, some organisations have found success by creating a culture of psychological safety, where blame is eliminated and employees are free to share ideas, questions, and concerns without fear of punishment.

One tactic on the hiring side is broadening the recruiting pool. Bringing in people from non-traditional backgrounds who may not have started in data centres but whose core skills can translate to changing the talent pool, making competitive hiring less of a restriction for new hires. This kind of hiring, when coupled with strong onboarding, can help seed teams with “raw” talent that can be shaped.
Bridging the skills gap in data centres requires more than just new hires; it demands a long-term commitment to training, cultural change, and new talent pathways. By investing in people as intentionally as they invest in infrastructure, data centre operators can ensure they have the resilient, skilled, and motivated teams needed to power the next decade of growth.
