Data Center Staffing 10-19-25

The number of IT jobs required to staff a data center varies from a few dozen to a few hundred, depending on its size, type (e.g., hyperscale, colocation), and business model. While large hyperscale centers can employ hundreds, smaller facilities may have a barebones staff of two to three dozen technicians handling the physical and network infrastructure, with other staff brought in as needed.  

Factors influencing staffing numbers

Size and type of data center:  Larger, more complex facilities require more staff than smaller ones. A hyperscale data center will have a different staffing model than a colocation facility.

Business model:  A colocation facility, which provides basic services, may require fewer core staff than a hyperscale facility that runs its own services.

Services provided:  The specific services the data center offers can impact the number and types of jobs needed. For example, managing customer-specific requests in a colocation center requires staff for technical assistance.

Automation:  As with any tech operation, the degree of automation can affect the number of staff needed to perform repetitive tasks. 

Typical roles found in a data center

Data center technicians: Handle the physical installation, maintenance, and management of IT equipment on-site. 

Network engineers:  Manage the network infrastructure and ensure data connectivity. 

Systems administrators:  Oversee the operating systems, servers, and other compute resources. 

Security staff: Monitor and maintain the physical and digital security of the facility. 

Facility and operations staff: Handle power, cooling, and other physical infrastructure, along with logistics for hardware. 

The number of IT jobs required to staff a data center varies significantly based on its size, function, and level of automation. Hyperscale cloud facilities operate with surprisingly few staff for their immense size, while smaller enterprise data centers may require more personnel per megawatt. The core operational staff can range from under 20 for a small site to over 100 for a large one,

in addition to specialized and contracted roles. 

Standard IT roles in data centers

Data center staffing generally includes three core teams that work in shifts to provide 24/7 coverage. 

IT operations team

Data center technician: The most common role, technicians are the front-line responders for hardware issues. Their duties include installing, configuring, and maintaining servers, network equipment, and cabling.

Network engineer: Manages network connectivity and infrastructure within the facility, including switches, firewalls, and routing.

Systems administrator: Manages server operating systems and applications. In a smaller facility, a technician might cover these duties.

Operations manager: Oversees the daily operations of the IT teams, managing schedules, training, and performance.

Logistics/asset management: Manages the inventory, shipping, and receiving of equipment and spare parts. 

Facilities team

Critical facilities technician/engineer: Operates, monitors, and maintains the electrical and mechanical systems that keep the data hall running. These include power (UPS, generators) and cooling (HVAC) systems.

Facilities manager: Oversees the entire physical infrastructure of the building, ensuring everything from power systems to groundskeeping is handled. 

Security team

Physical security officer: Provides on-site presence to control access to the building and monitor the data halls.

IT security specialist: Manages the logical security of the network and data, including firewalls and compliance protocols. 

Staffing benchmarks based on power capacity

A common method for estimating staff size is based on the data center's power capacity in megawatts (MW).

Small facilities (1–5 MW): 8–15 operational staff.

Medium facilities (5–20 MW): 15–35 operational staff.

Large facilities (20 MW+): 35+ operational staff.

Hyperscale facilities (40+ MW): While employing dozens to hundreds of people overall, these facilities are highly automated and require fewer employees per megawatt compared to smaller sites. 

Key factors influencing staffing numbers

Automation: Highly automated data centers use software to manage system diagnosis and server provisioning, reducing the need for hands-on technicians. Conversely, older, less automated sites require a larger on-site crew.

Reliability Tier: A facility with a higher reliability tier (e.g., Tier IV with 99.995% uptime) requires more staff per shift to ensure continuous 24/7 coverage.

Service model: A colocation site, which houses equipment for multiple customers, generally needs more staff for customer support, onboarding, and compliance than a dedicated enterprise-owned data center.

Temporary vs Permanent jobs: While construction of a large data center can require thousands of temporary workers, the number of permanent jobs is substantially lower.

Contracted labor: Many facilities outsource roles like physical security, janitorial services, and some technical maintenance to vendors, which reduces the number of direct, full-time employees.
