The role
What the job actually is
Data center technicians do the hands-on work on the floor: racking and stacking servers, running and dressing cables, swapping failed hardware, and acting as remote hands for teams that can't be on site.
The role is disciplined and procedural. You work through tickets, follow runbooks, respect maintenance windows, and document everything so the next shift knows exactly what happened. Reliability and safety matter more than speed.

- Military, logistics, or trades backgrounds used to procedure and shift work
- Recent graduates or career changers comfortable working with their hands
The facility
Where this role works
Your work is physical and on the floor: racking servers, running and dressing cables, and making the power connections at the rack. Compute, cabling, and the power that feeds each rack are where you spend your day.
Power chain
Utility to ATS to UPS to PDU to rack: the chain every outage question walks.
