[Star Wars] How the hell did the guys firing the Death Star laser even get that job?

Was it a lottery? What do they do when they're not pulling a lever and pressing a button? Other than getting cancer because they were 10 feet away from a planet destroying laser with no protective gear or even a guardrail.
