This isn't what is going on, at least in my opinion. This type of job posting means the government wants facebook to do something. To do "something", facebook needs employeees to perform that work. Whatever work this entails, the government would only like people with XYZ clearance to work on it. As an example, imagine Uncle Sam calls you(the CEO at facebook), and requests a list of dissidents based on ABC criteria, and would like that list and the research that produces it to be handled by people with security clearances. Your next step is to hire people with that security clearance, so they can do the work and you can start sending Uncle Sam invoices.
