Every layer of a data center has people behind it. This guide lists every job the series shows, what the work involves, and how people get into it.
These careers have many ways in: from trades like electrician or mechanic, from technical training, from IT, and from completely different jobs. Some people work on site every day; others are specialist contractors who come in to build and maintain.
Qualification names and licensing rules differ from country to country. Country-by-country routes will be added here. The guide grows with every episode.
Security and access
Security officers, reception and control room operators
The work
They are the first people every visitor meets, and the ones watching day and night. They check identities, issue passes, monitor cameras and alarms, and respond when something isn't right.
Ways in
Staying observant, communicating clearly and remaining calm matter more than anything technical. Customer service, hospitality and other security work are real starting points. Many countries require a security license or certified training for this role.
They install, test and maintain cameras, alarms and access control across the site.
Ways in
If you enjoy practical electronics and finding faults, this is a career worth exploring. Many come from alarm installation, networking or telecoms, or from an electrical or electronics apprenticeship.
They install, program and maintain the readers, locks and interlocked doors that decide who gets through.
Ways in
Precise, practical work for people who like electronics and logic. An electrical or electronics background is the usual start; training on specific systems mostly comes on the job.
They install and maintain the electrical supplies and lighting that every camera, reader and gate motor depends on, and much more as the series moves inside.
Ways in
A completed electrical apprenticeship or vocational qualification. If you already work as an electrician, this is work you would recognize, and one of the most common ways into the industry.
They work with the equipment at the incoming end of the power path, where the grid connection arrives.
Ways in
Specialist training and formal authorization for that work, built on electrical knowledge and experience. The exact requirements depend on the role and country.
