You'll quickly outgrow the existing codebase, especially if you are someone into modern web development. While they are trying to rebuild and make new modern websites, the biggest problem is lack of "cohesion" with the team. Most of the coding is outsourced, and communication about what's going on is terrible. The outsourced team may also replace you -- so there's that, they are trying to soak up whatever you know -- so you may end up being their teacher for free, lol.
Managers come and go, especially around senior management. I got the sense that most of the senior people just wanted to finish a few gigs -- pretty up their resume, and get out. There was no long term vision -- which makes it hard to grow your individual career.
