I've been in a similar situation. I found another developer with the same feelings about our (lack of) code quality as me and we put our desks opposite each other. This allowed us to exchange ideas and implement them in a positive environment. This worked well, and we quickly improved our deployment and testing practices. But refactoring the code was harder. Developers that had been there 10 years knew that starting to pull at X would break Y, so they were afraid of change. Of course they had experience to avoid most problems, and this knowledge was what made them valuable to the company. At any other company they would have been sub-par developers. Our improvement progress slowed down. We got tired of having to work really hard to get to the most basic industry standard, which were still far from stuff we could be really proud of. In the end we both quit, and it was the right decision. If you feel you have the support from other developers to make a change to your situation, then stay and do it with energy. But otherwise just move on, there is no point in wasting your time when there are so many better places.
