A retirement wave is thinning out the senior ranks in a lot of licensed and technical fields at once. The pipelines that replace those workers run on multiyear apprenticeships and long exam sequences, so a vacant seat can stay vacant for a very long time.
Meanwhile, younger job seekers keep steering toward flashier titles, which leaves the quieter work wide open to career changers. If you are trying to get ahead financially in the decade before retirement, that mismatch can work in your favor.
Employers in these fields will often train someone who already knows how to manage people, read a budget, or keep a crew on schedule. The work is rarely exciting, but the credential behind it tends to push pay into six figures.
Editor's note: All salary data is from the U.S. Bureau of Labor Statistics (BLS).
Actuary
Median annual salary: $130,000
Actuaries spend their days inside statistical models, estimating how likely accidents, illness, or natural disasters are and what each one would cost. It is quiet, spreadsheet-heavy work that quietly sets the price of insurance and pension products.
Typical entry-level education is a bachelor's degree in mathematics, actuarial science, statistics, or another analytical field, followed by a series of certification exams that can take up to seven years to reach associate status. Employers commonly pay for exams and study time, which makes the long runway easier to absorb for someone who already has an analytical career behind them.
Air traffic controller
Median annual salary: $148,080
Controllers watch screens, talk to pilots, and keep aircraft safely separated on the ground and in the air. Much of it is repetitive by design, because the whole point is that nothing surprising happens.
Typical entry-level education is an associate's degree, usually through an FAA-approved Air Traffic Collegiate Training Initiative program, and candidates must be U.S. citizens who pass medical evaluations, background checks, and preemployment tests before completing FAA Academy training. Military controller experience can substitute for the usual path, which is why some second-career applicants qualify when others cannot.
Elevator installer and repairer
Median annual salary: $109,910
These workers assemble elevator cars, wire control panels, and troubleshoot brakes, motors, and switches, then return for preventive maintenance on the same equipment. It is dirty, cramped, unglamorous work that almost nobody notices until a car stops between floors.
Typical entry-level education is a high school diploma or equivalent, with nearly everyone learning through a four-year apprenticeship, and most states require a license. Workers who can document relevant mechanical or electrical experience may qualify for a shorter apprenticeship, which matters a lot when you are counting working years.
Power plant operator
Median annual salary: $105,080
Operators read charts, meters, and gauges to track voltage and electricity flow, then adjust controls or start and stop generators as demand shifts. Most shifts are uneventful, and that is exactly how the job is supposed to go.
Typical entry-level education is a high school diploma or equivalent plus extensive long-term on-the-job training, and some operators are licensed by state boards as stationary engineers or boiler operators. Employers here train from the inside, so a candidate with plant, military, or industrial maintenance experience often starts well ahead of a raw hire.
Transportation, storage, and distribution manager
Median annual salary: $107,230
These managers run fleets, warehouses, and supply chain operations, juggling staff, budgets, and safety compliance behind every delivery. The day is meetings, schedules, and problem-solving on a deadline, not anything you would put in a movie.
Typical entry-level education is a high school diploma or equivalent, though many employers prefer a bachelor's degree and expect five or more years of related work experience. This is one of the friendlier fields for a career changer over 50, because prior supervisory experience is the main thing being hired for.
Nuclear power reactor operator
Median annual salary: $122,890
Reactor operators monitor turbines, generators, and cooling systems, adjust power output, and log data hour after hour. They also respond when something reads abnormally and direct maintenance and testing activities.
Typical entry-level education is a high school diploma or equivalent, but operators must be licensed through the Nuclear Regulatory Commission, usually starting as unlicensed operators and passing training, a medical exam, and the licensing exam before annual requalification. Navy nuclear experience transfers directly here, and licenses do not move between plants, so utilities have a standing reason to train people they already trust.
Compensation and benefits manager
Median annual salary: $149,230
These managers build a company's pay and benefits structure, track competitive wage rates, and manage outside vendors and brokers. It is policy documents, compliance checks, and enrollment deadlines, which is about as far from glamorous as office work gets.
Typical entry-level education is a bachelor's degree plus five years or more of related work experience, often starting as a compensation, benefits, and job analysis specialist, with voluntary certification helping job prospects. Decades of HR, finance, or management background is an asset rather than a liability in this seat.
Bottom line
The honest catch on every path here is time and money. Exams, apprenticeships, and licensing programs cost real dollars and can run for years before the bigger paycheck shows up.
Age bias in hiring is a genuine obstacle too, even in fields that openly cannot fill seats. Run the numbers on how many working years you have left and whether they cover the cost of the credential with room to spare.
The paths that tend to pencil out are the ones where your existing experience shortens the runway instead of starting you at zero. Before committing, it helps to get a clear read on where you stand financially today.
