Pros
Compensation package is great Saint Louis is a nice place to live, but there are few decent jobs. Area is part of Midwest's decline.
Cons
Leave your ethics at home. It's all about pumping up your many manager's incentive compensation packages. Nothing else matters. Good-ol-boy, backstabbing, political quagmire. Pick any group at the St. Louis area sites. It's the same. Highly cyclical funding environment littered with constant program cancellations, congressional budget cuts, and constant layoffs they call "redeployments". Extremely poor job stability. Be prepared for the Boeing version of "flextime". They send you home with a laptop and a 24/7/365 job. Plan on doing 3-5 people's jobs. It'll kill you, but It's great for the company's bottom line. Tech fellowship is a political joke. No career advancement unless a numbered parking space is what you want. Techies not valued, generalists are detested. Company is massively top heavy with engineers who are ill-suited for management in management jobs. High potential employees with whom you want to work to advance your career have already left.
