Well, it might be you who is doing something wrong. Based on your explanation you are not in any kind of leadership role. The company culture is mostly set around inputs proveded from the leadership. Things like what behaviour is tolerated, what kind of output quality is expected, tradeofs between speed and quality and so on. If you provided your feedback to the managers and they did not act on that it might be that they are on with such situation. And if that is the case and you don't agree with such views than you are probably not a good culture fit in the company. It might be a good idea to reevaluate you current position and move on. Don't settle for something and hope it will get better. You might be missing on a great oportunity waiting for you somewhere else with much better company culture for you.
