Well, I’m not at all familiar with the textile industry, but it’s possible that the listed qualifications would be consistent with a BS in “textile engineering” (who knew?), so this could be something that an applicant could qualify for directly out of college. $50k isn’t bad for a recent grad.
Also, I believe that government jobs tend to be lighter on salary, but heavier on benefits than non-government positions. My father was in the Air Force, and while his salary may not have been that impressive, my whole family had full medical/dental/vision coverage, housing was covered by the AF (either by living on base or getting a “rent stipend”), etc. That may or may not apply to people working for the CIA, though.
