How to break in

SECTION 02 — ENTRY ROUTES

ROUTE 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.
