Pros
The company genuinely cares for its employees. Management is actively engaged on making everyone's work easier and rewarding. All the engineers are very smart and a great resource for feedback. The company's first requirement (after technical capability) for hiring is to be nice and easy to work with, which makes for a really good feeling not to have to deal with a prima donna or someone who's always hard to talk to. With a technical staff of a few hundred, there are quite a few areas where skills can be honed, and while it may seem that the product is not incredibly exciting, there are options to change teams and pursue a professional interest. In fact, management encourages this. The work/life balance is very good. Remote work is available, and this is not a place where you will be required to put in 70 hours a week just to keep your job. The feeling is that as long as you do what you need to do, how and when you do it is a minor concern.
Cons
Salaries are not at the top of the scale for the best companies out there, however my personal take is that it is a small compromise for all the pros you get in exchange.
