Junior engineers can't change culture, they'd there to learn. Mid ranked engineers can improve culture by changing parts directly and encouraging others Senior engineers can hire and fire to get the company to work their way. Presumably you're midranked. If you are trying and its not working you either need Senior people on board or you learn to live with what you have. Do the best for your work and try to show the improvements you've done.
