Pros
I've been working here for just over three months. It's an exceptionally cool place to work - being involved in rocket launches is just, well cool. You get to think outside the box, come up with novel ideas to overcome challenges - I like that there isn't a "that's the way we've always done it" mentality and relatively light bureaucracy to get things done. Insurance is second to none - absolutely fantastic.
Cons
Work-life balance SUCKS. Work schedules constantly change (due to the nature of the business) and it's difficult to plan things. For those who want overtime, it's there in abundance. However, for those who do not want overtime, it's still there in abundance. Also, in my particular profession, vertical opportunities are slim. However, I lateral opportunities can exist if you're willing to go for it. Lack of a matching 401(k) is a big draw back; Also, in a field that is constantly evolving, tuition reimbursement would be a huge plus.
