Data Centre Jobs: What Is Real and What Is Not

Data centres are the construction story of the decade, and a whole layer of marketing has grown up underneath them. Short courses, certificates and recruiter posts all quote a salary for something called a data centre technician, usually with a number attached and often with the letters BLS somewhere nearby.

Here is the thing that should reframe the entire subject for you.

Why can I not find an official salary for data centre technician?

Because the occupation does not exist in the federal statistical system. There is no Standard Occupational Classification code titled data center technician. There is no Occupational Outlook Handbook page for it. Searching BLS for the term returns no occupational profile.

That is not a gap in your searching. It is a fact about the data, and it is the most useful thing this page can tell you, because it means every confident figure circulating for that job title was produced by somebody with an interest in the answer. A recruiter’s posted range is real information about a handful of postings. It is not a national survey of an occupation, and it cannot be compared to a BLS median.

When a training provider says “the BLS reports data centre technicians earn X,” they are quoting a number BLS does not publish. You can check that in about a minute on the BLS occupation finder, and it is worth doing in front of your teenager, because the habit transfers.

What are the nearest categories BLS does track?

There are two, and neither one is a match for the job title.

Computer support specialists is the nearest catch-all. BLS puts the median wage at $61,550 in May 2024, employment at 882,300 in 2024, and projects a decline of 3 percent from 2024 to 2034, which is a loss of 24,200 positions, alongside about 50,500 openings a year from replacement. Within it, computer network support specialists had a median of $73,340 in May 2024 and computer user support specialists $60,340. Entry routes vary: an associate degree is typical for network support, while user support commonly starts from some college courses or a high school diploma plus IT certifications.

Network and computer systems administrators is the other. BLS puts the median at $96,800 in May 2024, employment at 331,500, a projected decline of 4 percent for 2024 to 2034 or 13,800 positions, about 14,300 openings a year, and typical entry education at a bachelor’s degree. Source: BLS, network and computer systems administrators. Notably, that page does not mention data centres at all.

Two points of honesty about those declines. First, declining is not vanishing: BLS still projects about 50,500 openings a year for computer support specialists and about 14,300 for network and computer systems administrators, because replacement demand does not stop when growth does. If that distinction is new, it is explained properly in how to read a career growth statistic. Second, BLS does not attribute either decline to AI, and neither will this site.

Which trades actually build and run these buildings?

This is where the federal data gets solid again. A data centre is an electrical and cooling problem wearing a building, and the occupations that solve those problems are tracked in detail.

• Electricians. BLS projects 9 percent growth from 2024 to 2034, a net gain of 77,400 positions, and about 81,000 openings a year. Median wage $62,350 in May 2024, with the top ten percent above $106,030. Typical entry is a high school diploma and a four or five year apprenticeship. Source: BLS, electricians.
• HVAC and refrigeration mechanics and installers. BLS projects 8 percent growth for 2024 to 2034 and about 40,100 openings a year, with a median of $59,810 in May 2024. This is the one trade on our list where BLS lists a postsecondary certificate, not a diploma alone, as the typical entry credential. Source: BLS, HVAC mechanics and installers.
• Plumbers, pipefitters and steamfitters. Cooling systems are pipe systems. BLS projects 4 percent growth for 2024 to 2034, about 44,000 openings a year, and a median of $62,970 in May 2024 with the top ten percent above $105,150. Source: BLS, plumbers, pipefitters and steamfitters.
• Electrical power-line installers and repairers. Power has to arrive before it can be used. BLS projects 7 percent growth for 2024 to 2034 and about 10,700 openings a year, with a median of $92,560 in May 2024, the highest on our list. It is also dangerous work: BLS recorded a fatal injury rate of 13.8 per 100,000 full-time equivalent workers in 2024, against 3.3 for all workers, and BLS itself describes the hazards as high-voltage electricity, often at great height. Never read that wage without that rate. Source: BLS, line installers and repairers and BLS fatal injury rates, 2024.

One caution, because it is the mistake this page exists to prevent. BLS does not break these projections down by building type. None of the growth above is labelled as data centre demand by the agency that published it. What is fair to say is that the construction trades in this list are projected to grow while the two IT categories nearest the data centre job title are projected to shrink. That contrast is real, sourced and interesting, and it does not require anyone to guess.

What this looks like in practice

Ingrid’s daughter, who is seventeen, saw a fifteen week course advertised locally with a data centre technician job title and a starting salary in the advert. Ingrid’s instinct was that it sounded expensive, and she wanted to know whether the salary was real before she said anything.

She could not check it, because there is nothing to check it against. So she changed the question. Instead of asking whether the salary was accurate, she asked the school three things the FTC recommends asking any vocational programme: what percentage of students complete it, how many graduates find work in the field, and could she see the enrolment contract before signing anything. She also looked the programme up on TrainingProviderResults.gov.

Her daughter may well end up doing that course, and it may be good. The point of the exercise is that the advertised salary was never the evidence, and treating it as evidence is how families end up paying for a certificate that no employer asked for. This example is illustrative, but the three questions are taken directly from FTC consumer guidance.

What is the honest summary?

Data centres are real, large and being built. The jobs inside them are real too. What does not exist is a federal statistic describing the job title everyone is advertising, and a family that knows that is far harder to sell to.

If your teenager is drawn to this world, the two routes with actual published numbers are the electrical and mechanical trades on one side, and the IT categories on the other, which BLS projects to shrink modestly while still producing tens of thousands of openings a year. Either can work. Only one of them currently has people quoting invented numbers about it.

For the same reasoning applied to the wider AI question, see which jobs are actually safe from AI, and for the version of this worry that starts from the trades rather than from technology, see are the trades getting oversaturated.
