Pros
Engineering decisions are bottom up, not foisted upon from top managment, you get to choose what you think are projects that make for a better customer experience, and also make your life easier. The people who one works with make all the difference, the people here are bright, and friendly. The customer obsession thing is not a lie, which is somewhat refreshing after money grubbung at other firms.
Kontras
The operations burden can occassionally be a drag. And _everyone_ has an ops burden. Carrying a pager, and being a front line engineer has its pros -- interesting problems, triaging and diagnosing on the flyt -- but it can also be very tiring at the end of e week on call. When deadlines approach, there are times when one does spend more time at work than usual.
