Pros

Benefits are decent (not the best in the industry but also not the worst). You have a very specific job and are not expected to do other people's work (though there is a lot of sharing working within a department).

Cons

Management has unrealistic expectations of how time should be spent. Work is always coming in, and there's not enough time or people to do everything.
