> Total employment: 7,730
> Employment growth projection (2016-2026): +1.3%
About 5% of American workers commute using transit, according to CityLab estimates. This often means taking the train. Everyone who regularly travels by rail knows that tracks and switches malfunction often. Signal and track switch repairers are tasked with diagnosing and addressing the issues in these systems and fixing them to keep travelers safe and on time. Most signal repairers make more than $70,000 per year, nearly double the U.S. median annual wage of $38,640. This job typically requires just a high school diploma and no prior work experience for applicants.
19. Petroleum pump system operators, refinery operators, and gaugers
> Median annual wage: $70,860
> Total employment: 38,930
> Employment growth projection (2016-2026): +2.8%
Petroleum pump system operators, refinery operators, and gaugers help to set up oil wells and ensure that they continue pumping. As part of the generally higher-paying oil and natural gas industry, these workers are well compensated. Most earn over $70,000 per year. As renewable energy becomes more common, oil and gas industry jobs may be drying up. Total employment for pump system operators is only projected to grow by 2.8% by 2026 — well below the 7.4% growth projected across all jobs in the same time frame.
18. Electrical power-line installers and repairers
> Median annual wage: $70,910
> Total employment: 114,800
> Employment growth projection (2016-2026): +13.9%
With electricity powering cell phone chargers, TVs, and computers, our power grids are more important than ever. The power line installer field is expected to be one of the fastest growing in the country. There are projected to be 13.9% more installers and repairer jobs in 2026 than there were in 2016 — nearly double the projected overall U.S. job growth. As of May 2018, there are already over 100,000 power line installers and repairers.
17. Gas plant operators
> Median annual wage: $71,070
> Total employment: 14,620
> Employment growth projection (2016-2026): +0.0%
Gas plant operators ensure that natural gas plants safely store and distribute gas. Though this job does not require a college degree or work experience, it can take a long time to become familiar with all the equipment used in a gas plant so operators typically need long-term on-the-job training to become proficient. The BLS projects no growth in the profession from 2016 to 2026.
16. Ship engineers
> Median annual wage: $71,130
> Total employment: 8,740
> Employment growth projection (2016-2026): +6.5%
Though ship engineer jobs do not require a four-year college degree, running and maintaining all the engines, boilers, and machinery on board a ship is a difficult skill set to acquire. Licensing exams for engineers typically require several years of maritime experience in lieu of education. As with many jobs that require significant expertise, ship engineers are well paid. Most earn more than $71,000 annually.
