Pros
Where else in the world do you get to contribute to the design and engineering of some of the most complex pieces of machinery in existence. At Boeing you have the opportunity to work on everything from software to spaceships, from nuts and bolts to entire airplanes. It is the best place I have ever worked.
Cons
Typical large company bureaucracies. Cost cutting measures starting to show in benefits reductions for non-union employees (benefits still better than most of the world). Seemingly short sighted view of the world by senior executives. High overtime was fine when we were compensated for it but starting Jan 2014 managers will no longer get paid for more than 40 hours a week but are expected to work it. (I average 50 to 60 hours a week)
