Pros
Pay if you negotiate it good. Otherwise, it can be below industry average. People are nice in general as long as you do not point that something can be improved because it automatically means it was designed wrong. As long as you do not go against the grain they will be nice to you.
Cons
In January, 2013 15 employees were laid off. In September, 2013 19 salaried employees were laid off. In March, 2014 11 salaried employees were laid off. ATK in Clearwater lost a big program because of not meeting deadlines, lying to, and hiding faulty design from the only customer they have. Right now, almost half the employees are on overhead charge number which means they are waiting to get laid off. Everyone who is hard working and contributor already left or is looking for job somewhere else and wants to jump out of the sinking ship. ATK in Clearwater used to have good reputation, but now its reputation is the lowest ever. Managers blame each other with no idea how to secure new contracts. The so called most experienced engineers here are just trying to collect as much as possible before retirement working at the slowest possible pace. Too much frustration around here while poor management and corrupted engineers try to hide faulty design from the only one customer they have. Too many dinosaur engineers very angry and hostile to coworkers. Run away from this place. Actually, you do not have to because they will not be hiring for decades to come.
