Some teams have operational and funding issues, so your experience there may be hellish. You could think of it another way and realize that you have your work cut out for you. I previously worked on an AWS team like this and left because I got tired of the grind.

On the other hand, a lot of teams are great places to work. Before I left AWS, I worked on a really good team with intelligent co-workers and interesting engineering challenges. It was like night and day - the team was over-funded and had very few operational issues.
