Data Center Hiring Report: September 2026 | UptimeJobs
An UptimeJobs.io Snapshot
Welcome to the second edition of the UptimeJobs Data Center Hiring Report. Last month we established an August baseline; this month, for the first time, we can show movement — how data center hiring shifted from August to September across three core categories: Data Center Operations, Power & Cooling, and Construction & Facilities.
A note on method: Figures are a point-in-time snapshot taken near the end of each month, deduplicated to distinct roles (the same opening posted to multiple locations or boards is counted once). This report covers those three categories inclusive of all their listings, not our entire board. Month-over-month figures compare the September snapshot to August's.
The headline: hiring grew
Distinct open roles across the three categories rose from 126 in August to 165 in September — a jump of roughly 31%. Whatever anxieties the "data center backlash" headlines have stirred, the hands-on hiring market got busier, not quieter, heading into the fall.
Who's hiring: QTS pulls ahead
The biggest shift this month is at the top. QTS surged to the largest employer by distinct openings — 46 roles, or 28% of the total — overtaking Amazon and every other operator. QTS is hiring aggressively across critical operations, facilities engineering, and construction.
The updated leaderboard:
| Employer | Sept distinct openings | Share | vs. August |
|---|---|---|---|
| QTS | 46 | 28% | ▲ up |
| Amazon | 22 | 13% | ▼ down |
| CyrusOne | 21 | 13% | ▲ up |
| Vantage | 16 | 10% | ▲ up |
| Oracle | 9 | 5% | — |
| Microsoft | 7 | 4% | — |
A few movements worth noting: Amazon's distinct openings fell (from ~20% of the market to 13%), while CyrusOne and Vantage both grew. The result is a market that's slightly less top-heavy than August — the two largest employers now account for 41% of openings, down from 45% — even as the top three hold steady at 54%. In plain terms: still concentrated, but the hiring is spreading across more of the major operators than it was a month ago.
What they're hiring for
The role mix held consistent with August — demand is overwhelmingly for hands-on technical work:
- Data Center Operations remains dominated by the Data Center Technician role, led by Amazon, Microsoft, and Oracle.
- Power & Cooling grew notably, led by Critical Environments Operators (CyrusOne), Critical Operations Technicians (QTS), and Critical Facilities Engineers (Vantage). This was the fastest-growing category.
- Construction & Facilities stayed strong, heavy on development and construction project managers — reflecting continued buildout despite the permitting friction making headlines in some states.
The 24/7 shift-work pattern persists: a meaningful share of technician and operator roles are explicitly night, swing, or overnight positions.
Where the jobs are
The geography barely moved — the same markets lead, with Georgia and Ohio continuing to grow:
| State | Sept distinct openings |
|---|---|
| Texas | ~29 |
| Virginia | ~24 |
| Georgia | ~18 |
| Ohio | ~14 |
| Arizona | ~11 |
(Geography is directional — derived where a specific location was listed; some roles were remote or nationwide.)
Texas and Virginia continue to anchor the market, with Texas extending its lead. Georgia (Atlanta) and Ohio (Columbus/New Albany) keep climbing as secondary hubs — consistent with the campus buildouts underway in both.
The bottom line
September's data tells a clear story: hiring grew ~31% month-over-month, QTS pulled ahead as the most active employer, and the market broadened slightly across the major operators — all while staying concentrated, hands-on, and clustered in Texas and Virginia. Despite the friction headlines around permits and financing, the demand for the people who build and run data centers rose.
Next month, we'll see whether QTS holds its lead, whether Amazon's openings rebound, and whether the fall buildout keeps pushing the numbers up.
