Pros
We do some of the most awesome work in the world and you will get as much responsibility and ownership as you can handle. I've learned so much in the almost 6 years that I've worked here and I'm very grateful for that. We're on the cutting edge of technology and really changing the aerospace world. Benefits package is actually quite good.
Cons
As many say the hours can be daunting and the pressure from management to meet unrealistic deadlines is relentless and that flows from the top down. Work life balance here can be miserable if you succumb to the pressure and the expectation that you're on call 24/7 which is not sustainable. Because of this many good people burn out and leave the company. There's no clear path for any career development at this company. Seemingly people get promoted by either being the most senior person in the group or that they work more hours than everyone else. But for every one of each of these there's someone who got promoted for seemingly no reason at all. Generally pay is low compared to many other industries including our own and we use the "cool" factor as justification for not paying people as much. The equity argument is now essentially irrelevant as most of us with a meaningful amount of equity have vested and any new offers are comically small in comparison. Plus this is not a publicly traded company so..... yea.
