Also called: RFI Engineer, Radio Frequency Interference Specialist
Hunts down stray radio signals, from microwave ovens to spark plugs, that would drown out faint cosmic signals at radio telescopes.
At Green Bank Observatory in West Virginia, inside the 13,000-square-mile National Radio Quiet Zone, you drive a truck fitted with antennas to track a buzzing electric fence or a neighbor's Wi-Fi router. You review plans for new cell towers in the zone, test every gadget brought onto the site, and kindly ask a farmer to swap an old, noisy motor.
Approximate: anchored on Bureau of Labor Statistics data for a broader job group.
Bachelor's degree (4-year), about 4 years after high school. Bachelor's in electrical engineering or physics with radio-frequency (RF) skills.
Ways in: 4-year college. Training cost: $15k – $60k.
Majors to look at: Electrical Engineering, Physics, Engineering Physics.
Growing about average. Tiny niche at a few radio observatories; RF skills transfer widely.
Low risk for 10 years. AI helps sort signal logs; driving out to find a buzzing power line and persuading its owner to fix it stays human.
Classes: Physics, AP Calculus, Electronics or robotics.
Official data: O*NET occupation 17-2072.
