Also called: Mass Spectrometer Leak Tester, Leak Test Technician
Finds leaks so tiny that only helium atoms can slip through, in parts like pacemakers, satellites and chip-making tools.
You seal a medical implant in a vacuum chamber and spray helium around it. A mass spectrometer listens for even a few helium atoms getting through. When you find a leak on a satellite valve, you pinpoint it with a probe and report it to engineers.
Approximate: anchored on Bureau of Labor Statistics data for a broader job group.
Certificate, about 1 year after high school. High school or associate degree plus leak testing certification.
Ways in: On-the-job training, Certification, 2-year college. Training cost: Under $15k.
Majors to look at: Nondestructive Testing Technology, Vacuum Technology.
Growing faster than average. Chips, EV batteries and medical devices need tighter leak testing.
Medium risk for 10 years. Production leak tests are automated, but hunting down tricky leaks and judging results stays human.
Classes: Chemistry, Physics, Algebra, Shop class.
