Industrial machinery installation and maintenance

Millwrights

Millwrights install, align, repair, and maintain heavy machinery in factories, power plants, and other industrial sites. The work is unusually precise for a hands-on trade: one bad alignment can cause vibration, breakdowns, or safety problems, but the job also means working with heavy equipment, tight shutdown windows, and a lot of physical labor. The tradeoff is solid pay and steady demand without a degree, but little growth in the number of jobs.

Pros and Cons

Advantages
+ Pay is solid for a trade, with a mean annual wage of $68,640 and a median of $65,170.
+ You can enter the field with a high school diploma and apprenticeship instead of a four-year degree.
+ Annual openings are projected at about 3,600, so replacements and retirements still create jobs.
+ The work is hands-on and concrete: you can see a machine go from broken or misaligned to running again.
+ Skills such as alignment, troubleshooting, and preventive maintenance transfer across factories, plants, and utilities.
Challenges
- Employment is projected to stay flat at 41.3K from 2024 to 2034, so this is not a fast-growing field.
- The job is physically demanding, with heavy lifting, awkward positions, climbing, and long periods on your feet.
- There are real safety risks around moving parts, hoists, welding, and energized equipment.
- Work often depends on shutdowns, outages, or major repairs, so hours can be intense and schedules uneven.
- Earnings can plateau unless you move into supervision or specialized industrial maintenance, which limits the ceiling for many workers.
