Pros
My program had really good people. Work/life balance was pretty good but is on the decline with forced RTO and 9/80s. Can be a good stepping stone - spend a few years here before leveraging that to a higher salary at a better company somewhere else.
Cons
This company, particularly LM Space, is on a noticeable downward trend. RTO mandates, forced 9/80s (ironically after forcing 4/10s a few years prior), bad benefits, increased vesting period, no company outings any longer, etc. The pay is also pretty bad, it's basically on par with the other big defense contractors in the region. Forced full-time office work in a SCIF sucks. Management will never admit it, but many programs are ultimately a "butts in seat" operation. They cannot keep good people on the program since the pay isn't great and full-time on site SCIF work sucks so often times the only ones staying are terrible workers that have no other options.
