SECTION 02 — ENTRY ROUTESROUTE A
Electrician / Mechanical
You already understand power, cooling, and safety. Data centres need your skills — they just call them "critical facilities" instead of "building services."
First step: Apply for Critical Facilities Engineer roles. Emphasise HV experience, emergency response, and your ability to read schematics.
ROUTE B
IT / Network Engineer
You know servers, networks, and troubleshooting. The physical layer is just another layer — and data centres are where the physical meets the digital.
First step: Apply for Data Centre Technician roles. Learn power and cooling on the job. Your IT background makes you promotable fast.
ROUTE C
Ex-Military / Ex-Forces
Discipline, procedure, and working under pressure — data centres run on all three. Your clearance and operational experience are assets.
First step: Look for facilities roles that value security clearance. Many defence contractors have data centre divisions.
ROUTE D
Career Changer
No relevant background? Start with a certification (CompTIA, BICSI, or a data centre-specific course) and apply for entry-level technician roles.
First step: Get any cert that proves you can learn. Apply broadly. The first role is the hardest — after that, experience counts.
