Data center workforce shortage statistics show a gap that has lasted for years and is now being stretched by the AI build out.
Nearly half of operators still cannot find qualified candidates, 87% say workforce gaps are affecting their operations, and the construction trades that build new sites need hundreds of thousands of new workers a year. Below are the key numbers, with the source and year for each one.
Key takeaways
- 46% of data center operators have difficulty finding qualified candidates, and 37% struggle to retain staff (Uptime Institute, 2025).
- 87% of data center professionals say workforce gaps are affecting operations, up from 85% a year earlier (AFCOM, 2026).
- Data center engineers are the hardest role to fill, cited by 56% of respondents, up from 50% (AFCOM, 2026).
- The U.S. construction industry must attract 349,000 net new workers in 2026 and 456,000 in 2027, with electricians in especially short supply (Associated Builders and Contractors, 2026).
- About one fifth of all electricians are over 55 (Associated Builders and Contractors, 2026).
- 80% of data center operations teams are 10% women or less (Uptime Institute, 2024).
How many data center operators struggle to hire?
Roughly half, and that share has barely moved in years. Uptime Institute asks operators in its annual global survey whether they have difficulty finding qualified candidates for open roles. In the 2025 survey of more than 800 owners and operators, nearly two thirds reported trouble hiring, keeping staff, or both.
| Survey year | Operators with difficulty finding qualified candidates |
|---|---|
| 2018 | 38% |
| 2021 | 47% |
| 2022 | 53% |
| 2024 | 51% |
| 2025 | 46% |
The small dip since 2022 does not mean the problem is solved. Demand has kept climbing: North American primary market vacancy hit a record low of 1.4% in H1 2026, according to CBRE, and every new site needs a full operations team. Our data center statistics page covers the market growth behind the hiring pressure.
Is it getting harder to keep data center staff?
Retention is now as big a problem as hiring. Uptime Institute’s 2025 survey found:
- 37% of operators struggle to retain staff.
- 35% say staff are being hired away by competitors.
Poaching has been a concern for years. In Uptime’s 2022 survey, 42% of respondents said staff were being hired away, compared with 17% in 2018. In 2024, 22% said they had lost staff specifically to other data center organizations. Question wording has changed between surveys, so treat these as a direction of travel rather than a single trend line. The steady message is that experienced people have options and use them.
Which data center roles are hardest to fill?
Engineers top the list. AFCOM’s State of the Data Center 2026 report found that 87% of respondents say workforce gaps are affecting their operations, up from 85% the year before. The most in-demand roles were:
| Role | Share of respondents naming it most in demand |
|---|---|
| Data center engineers | 56% (up from 50%) |
| Multi-skilled data center operators | 40% |
| Power systems and energy engineers | 36% |
| Security specialists | 36% |
The same report found the most common responses to the shortage were retraining and upskilling existing staff (36%) and outsourcing more services (33%). If you are defining one of these roles, our guide to what a data center engineer does breaks down the critical facilities and IT tracks.
Does the staffing shortage cause outages?
Staffing plays a large part. When Uptime Institute asked operators about the root causes of operational issues in its 2022 survey, it found:
- 36% pointed to staff execution.
- 28% pointed to insufficient staffing.
- 21% pointed to incorrect procedures.
The cost of getting it wrong is high. In the 2025 survey, 50% of operators reported at least one impactful outage in the past three years, and 20% of significant outages cost more than $1 million.
Is there an electrician shortage for data centers?
Yes, and it hits construction first. Associated Builders and Contractors estimated in January 2026 that the U.S. construction industry must attract 349,000 net new workers in 2026 and 456,000 in 2027. ABC said demand for electricians capable of precision wiring has surged because of rapid growth in data center construction, and that about one fifth of all electricians are over 55.
Federal data points the same way. The Bureau of Labor Statistics counted about 821,000 electrician jobs in 2025 and projects about 72,700 openings a year through 2035, many of them to replace workers who retire or leave the trade.
Which data center trades and engineering jobs are growing?
BLS does not track data center jobs as a separate occupation, but the core roles that build and run them are all projected to grow faster than average. These figures cover all industries.
| Occupation | Jobs (2025) | Median pay (May 2025) | Projected growth, 2025 to 2035 | Average openings per year |
|---|---|---|---|---|
| Electricians | 821,000 | $63,190 | 9% | 72,700 |
| HVAC mechanics and installers | 440,900 | $61,010 | 11% | 40,600 |
| Mechanical engineers | 298,500 | $104,110 | 11% | 17,800 |
| Electrical engineers | 199,700 | $120,630 | 10% | 16,300 (with electronics engineers) |
Data centers compete for these same workers with utilities, manufacturing, hospitals and commercial construction. That is why experienced critical facilities engineers often command pay well above these national medians, especially on night shifts or at large AI campuses.
Recruiter tip: The deepest untapped pools we see are adjacent critical environments: Navy electrical and nuclear veterans, power plant operators, hospital plant engineers and field service technicians who already maintain UPS, switchgear and chillers. They know the equipment and the procedures. What they usually need from an employer is a clear training path into data center operations and a schedule they can live with.
How big is the data center workforce?
Larger than most people assume. A 2026 study by PwC for the Data Center Coalition found the U.S. data center industry directly employed 1,005,080 people in 2024 and supported 5.5 million jobs in total, up 17% from 4.7 million in 2023. Each direct job supports more than 4.5 jobs elsewhere in the economy.
Globally, Uptime Institute’s first staffing forecast, published in January 2020, projected that data center staff requirements would grow from about 2 million full-time employees in 2019 to nearly 2.3 million by 2025. That forecast came before the AI build out began, so it likely understates today’s need.
How many women work in data centers?
Very few, which leaves a large part of the potential talent pool untapped. According to the Uptime Institute Global Data Center Survey 2024:
- 80% of operations teams are 10% women or less.
- 20% of organizations employ no women at all in operations.
- Only 4% report an equal ratio of men to women on their operations staff.
Will AI reduce data center staffing needs?
Not soon, according to operators. In Uptime Institute’s 2022 survey, only 19% expected AI to reduce operations staffing within the next five years, down from 29% in 2019. Just over half (52%) expected AI to reduce staffing eventually, but not within five years. Meanwhile, AI is the main reason new capacity is being built, which adds far more jobs than monitoring software removes.
What do these numbers mean for employers?
The shortage is structural, not a blip. Hiring difficulty has hovered around half of operators since 2021, retention has become a second front, and the trades that build new capacity are aging. Employers who do well in this market tend to start hiring operations staff during construction, recruit from adjacent industries, invest in training, and put pay, differentials and schedules in writing up front.

Frequently asked questions
Is there a shortage of data center workers?
Yes. Uptime Institute’s 2025 survey found 46% of operators struggle to find qualified candidates, and AFCOM’s 2026 report found 87% of respondents say workforce gaps are affecting their operations.
What data center jobs are most in demand?
Data center engineers lead AFCOM’s 2026 list at 56%, followed by multi-skilled operators (40%), power systems and energy engineers (36%) and security specialists (36%). On the construction side, electricians are the biggest constraint.
Why is it so hard to hire data center staff?
Demand is growing faster than the pool of people with hands-on experience in live power and cooling systems. Many experienced workers are nearing retirement, few women have been recruited into the field, and data centers compete with utilities, manufacturing and construction for the same electricians and engineers.
How many people work in the U.S. data center industry?
PwC found 1,005,080 direct employees in 2024, with 5.5 million total jobs supported across the U.S. economy.
