Good people

Pros

Work with smart, talented individuals. Work on large complex electro-mechanical hardware. Work-life balance is up to you (some people are workaholics, others not so much). People that are lazy and/or incompetent generally don't last too long here (though there are some exceptions)

Cons

Pay is always on the low end of acceptable. You aren't going to retire early working here. Slow progress, growing pains. Some parts of the company and a bit of a mess and disorganized.
