Phoenix has the largest semiconductor manufacturing buildout in American history under construction right now. TSMC's $165 billion campus in north Phoenix. Intel's $8.5 billion CHIPS Act expansion at Ocotillo in Chandler. Over 50 semiconductor company expansions across the state since 2020, totaling more than $205 billion in announced investment through the end of the decade. Per the Arizona Commerce Authority, an estimated 25,000 current and upcoming roles in Arizona are directly linked to semiconductor manufacturing.

The fabs are being built. The workforce to build and run them is not. The Associated General Contractors of Arizona reports that over 80% of the state's construction firms are struggling to fill both craft and salaried roles. TSMC has publicly delayed its second Arizona fab opening citing skilled labor shortages. A 2023 study from the Semiconductor Industry Association and Oxford Economics projected that 67,000 semiconductor-related jobs nationally would go unfilled by 2030 — and the most acute shortages are among skilled technicians and craft trades, not engineers.

This is what makes Phoenix in 2026 a uniquely structured opportunity. McKinsey's analysis of fab workforce needs is direct: building a semiconductor fab depends on welders, electricians, pipefitters, carpenters, and other craft laborers. Operating one needs trained technicians. Both labor pools are short in Arizona, and the trades pool is short by tens of thousands of workers nationally.

Below: five trades where Arizona employers are hiring hardest right now — plus two honorable mentions for adjacent specialties the state's growth is pulling along with it.

#1 — Electrician

Semiconductor fabs are among the most electrically intensive structures ever built. A single advanced fab consumes more power than a small city. Every fab requires thousands of electricians during the multi-year construction phase, and significant ongoing electrical work to maintain power infrastructure once production begins.

TSMC's Phoenix campus alone spans more than 1,000 acres with six fabrication plants planned, two advanced packaging facilities, and a research and development center. Intel's Ocotillo expansion is the largest in the company's history. The combined electrical work on these two campuses represents one of the largest concentrated electrical construction projects in the country.

BLS projects electrician employment to grow 11% nationally from 2023 to 2033 — much faster than average — with about 80,200 openings each year. Phoenix's structural demand is well above that national rate. The Refrigeration School (RSI) in Phoenix offers an electrical/electrical-mechanical program that trains students for entry into these markets.

#2 — HVAC Technician

HVAC demand in Phoenix is dual-track. There's the residential and commercial baseline driven by Arizona's extreme heat — Phoenix routinely sees over 100 days a year above 100°F, and that demand never slows. Then there's the specialized cleanroom and data center HVAC work that the semiconductor build-out is creating.

Cleanroom HVAC for fabs is one of the most demanding niches in the trade. Semiconductor manufacturing requires extreme precision in temperature, humidity, and particle control — far beyond commercial HVAC standards. Technicians with cleanroom experience can command premium wages on industrial contracts. Phoenix is also rapidly becoming a major data center hub, which requires similar mission-critical HVAC expertise.

The Refrigeration School in Phoenix has trained HVAC technicians since 1965 and is one of the longest-running HVAC programs in the country. Their seven-month accelerated program puts graduates into the workforce quickly — which matters when Arizona contractors are reporting acute labor shortages.

#3 — Pipefitter

Pipefitting at a semiconductor fab is a specialized industrial trade. Fabs require extensive piping infrastructure: chemical delivery systems, ultrapure water lines, gas distribution, process cooling loops, exhaust scrubber systems. Each of these requires certified industrial pipefitters working to extremely tight tolerances.

A single fab can require miles of specialized piping, installed by pipefitters who have to pass certification tests before they're allowed near the systems.

The Phoenix metropolitan area has the seventh-highest employment level for plumbers, pipefitters, and steamfitters in the country, per BLS. And the U.S. Department of Labor's CareerOneStop projects a 30% growth rate for plumbers, pipefitters, and steamfitters in Arizona through 2032 — compared to just 2% nationally over the same period.

BLS projects approximately 44,000 annual openings nationally for plumbers, pipefitters, and steamfitters through 2034 — much of it replacement hiring as the workforce ages out. Industrial pipefitting specifically remains one of the highest-paid niches in the trade, with experienced pipefitters working semiconductor and energy contracts in Arizona commanding premium wages.

#4 — Welder

Fab construction requires structural welding for the building itself, mechanical welding for cooling and exhaust systems, and specialized pipe welding for the industrial piping that runs through every fab. Beyond semiconductor work, Arizona's broader construction boom is pulling welders into commercial development, data center infrastructure, and manufacturing facilities at the supply chain layer.

~45,600

The average skilled construction worker today is over 50 years old, and for every five workers leaving the industry, roughly one new worker enters. That demographic crunch is hitting Arizona harder than most states because the semiconductor build-out is layering new demand on top of an already-tight market.

The Refrigeration School in Phoenix offers a Welding Specialist program that prepares graduates for structural, pipe and pipeline, and thin alloy welding — exactly the welding specialties Arizona's industrial growth requires. Universal Technical Institute (UTI) also operates a Phoenix campus with welding training.

#5 — Construction Manager

Phoenix is described in industry analysis as one of the most active construction markets in the United States. Multi-billion-dollar projects from TSMC, Intel, hyperscale data center operators, and infrastructure expansion are all running concurrently. Each of those projects requires construction managers with significant industrial or mission-critical experience.

The senior construction manager market in Phoenix is particularly tight. Semiconductor fab construction requires PMs who understand mission-critical environments — clean room construction sequencing, specialized contractor coordination, and industry-specific safety standards. That credential is rare, and the few PMs who have it are commanding premium wages on Arizona contracts.

BLS projects construction manager employment to grow 9% from 2023 to 2033, with about 41,400 openings each year nationally. Construction management is typically a career progression role rather than an entry-level trade school path — many CMs come up through electrical, mechanical, or general contracting work before moving into project management.

Honorable Mention — Diesel Mechanic

Arizona's growth is pulling logistics infrastructure along with it. Phoenix sits at the intersection of I-10 and I-17, making it a major distribution gateway for the Southwest. Major distribution centers and growing freight volume mean steady demand for diesel mechanics to maintain fleet operations.

The semiconductor build-out adds another layer: fab construction requires heavy equipment, and that equipment needs diesel mechanics for maintenance and repair. Universal Technical Institute (UTI) operates a Phoenix campus with diesel mechanic training.

Honorable Mention — Aircraft Mechanic

Phoenix Sky Harbor is one of the busiest airports in the United States, and Arizona hosts significant aviation maintenance operations beyond commercial aviation — including military, general aviation, and aerospace work. The national A&P (Airframe and Powerplant) mechanic shortage is structural, and airlines can't find mechanics at the volume the industry requires.

Aviation Institute of Maintenance (AIM) operates a Phoenix campus offering FAA-approved A&P certification programs. For someone certified or pursuing A&P certification, Phoenix is a meaningfully strong market — and one that runs counter-cyclically to many of the other trades on this list, providing stability even when construction slows.

The bottom line

Arizona is the most heavily capitalized semiconductor manufacturing corridor in the Western Hemisphere right now. $205 billion in announced investment. 25,000 semiconductor-linked roles. TSMC and Intel both expanding aggressively. Over 80% of Arizona construction firms struggling to find workers.

This is what a structural labor shortage looks like in real time. The companies are there. The capital is committed. The buildings are going up. What's missing is the workers — specifically the skilled trades that build and maintain the infrastructure semiconductor manufacturing requires.

When the largest industrial buildout in American history can't find enough workers, the people who step in now are the ones who shape the next decade of Arizona's economy.

For someone weighing a career bet in 2026 — Phoenix is the most underserved trades market in the country relative to its growth pipeline. The work isn't speculative. It's happening now, on the ground, and Arizona employers are openly saying they don't have enough people to do it.
