Job postings love to throw around the phrase "no experience necessary" and then quietly expect three years of relevant background anyway. The roles below are different because many are built around structured training, licensing, or apprenticeship programs designed for people starting from zero.
That matters if you are switching careers or getting a strong start without taking on student debt first. You put in time on the job, pass the required checks, and build skills while you are already earning, which is worth weighing as you check up on your financial health.

Elevator and escalator installer and repairer
Median annual salary: $109,910
These workers install, maintain, and fix elevators, escalators, and moving walkways, reading blueprints, wiring components, and troubleshooting problems with brakes, motors, and control systems.
A high school diploma or equivalent is the typical entry bar, and nearly everyone learns the trade through a four-year paid apprenticeship, with most states requiring a license once you are trained.
Power plant operator
Median annual salary: $102,040
Power plant operators monitor charts, meters, and gauges to track voltage and electricity flow, adjusting controls to keep power moving where it needs to go.
A high school diploma or equivalent gets you in the door, followed by extensive long-term on-the-job training, though nuclear plant operators also need a license from the Nuclear Regulatory Commission.
Signal and track switch repairer
Median annual salary: $92,460
These technicians install, inspect, test, and repair electric gate crossings, signals, and track switches that keep railroad systems running safely.
No prior related work experience is required. A high school diploma or equivalent plus moderate-term on-the-job training is typically enough to become proficient.
Transit and railroad police
Median annual salary: $90,230
These officers patrol train yards, subway stations, and transportation hubs, protecting riders and employees and keeping unauthorized people off secure property.
A high school diploma or equivalent is the usual starting point, and candidates usually must be at least 21, meet physical and personal qualifications, and graduate from their agency's training academy before finishing on-the-job training.
Subway and streetcar operator
Median annual salary: $86,380
Subway and streetcar operators run subway trains and electric streetcars along fixed routes, transporting passengers and sometimes handling fares along the way.
No prior experience in a related field is needed. A high school diploma or equivalent is typical, and workers learn the job through moderate-term on-the-job training.
Police and detective
Median annual salary: $77,310
Police officers patrol assigned areas and respond to calls, while detectives gather evidence, interview witnesses, and build cases for court.
Education ranges from a high school diploma to a college degree, depending on the agency. Police officer roles can be entry-level, while detectives typically gain experience first as officers. Entry requires graduating from a police academy and completing on-the-job training, plus possibly passing written, physical, polygraph, and drug tests.
Patrol officer
Median annual salary: $76,210
Patrol officers watch over assigned areas, respond to emergency and nonemergency calls, conduct traffic stops, and make arrests when necessary.
A high school diploma or equivalent is the baseline, though some agencies want college coursework, and candidates must be at least 21, pass rigorous physical and personal standards, and graduate from their agency's training academy before completing on-the-job training.
Electrical and electronics installer and repairer
Median annual salary: $74,490
These technicians diagnose and fix faulty equipment, talking through problems with customers, testing devices, and swapping out broken parts before reassembling and retesting the gear.
A high school education is the baseline, though most specializations call for further preparation through advanced education, an apprenticeship, or work experience, and employers often provide on-the-job training.
Rotary drill operator, oil and gas
Median annual salary: $67,890
Rotary drill operators set up and run drills to extract oil, gas, or core samples, and they direct the work of derrick operators and roustabouts on the rig.
No formal educational credential is required. Workers typically learn through hands-on oil and gas experience, though some related experience may be expected, and those moving equipment between jobsites need a commercial driver's license.
Bottom line
These jobs prove that solid pay and an open door are not mutually exclusive. You do not need a four-year degree to clear $65,000; you just need to pass a test, finish training, or stick with an apprenticeship long enough to build real skill.
That is a meaningful difference if you are trying to get out of debt rather than borrow more to chase a credential. Paid training means your income starts on day one instead of after graduation.
If you are ready for physical work, licensing exams, or structured training, these fields deserve a serious look. The barrier is not a diploma on the wall; it is showing up and proving you can do the work.
