Pros
Lockheed Space Systems has some really nice systems integration programs to cut your teeth on. There's some good people to work with.
Kontras
It's always seemed like a rat race that's induced by the company culture. There's very few opportunities to "move up" when you're mid-career. Benefits are terrible, and Salary was never positive. I earned less each year because of the minimal salary increases, and increase in benefits costs. When programs get lean, management has typically asked employees to contribute at least 10 hrs of overtime uncompensated prior to consideration for overtime. When annual compensation raises were around the corner, having contributed 10 hrs of uncompensated overtime was the status quo, and even then you may see a 1.8% increase on an under market salary. Upper management seemed to be heavily pepperd with cronyism... I've never seen such flagrant application of it. There was a wall of management at every step of the way. I was always in fear of my position being eliminated. Management would say "last one in, first one out" regardless of experience that I brought to the team.
