Ask HN: Startup Co-Founder Only Trusts Seed Team

I joined a startup this year, and the CTO only trusts those who joined him during the seed phase. It's two years old and he doesn't give newcomers a chance. He's trying to hire senior engineers, and I'm one of them, but he doesn't give us the freedom to do things our way. For everything, he wants things done the way his pet developer does it, and that's usually Django-driven. The HR is powerless, since they report to the CTO as well (CEO manages global operations), so what are my options? I feel like I should leave, but I'm not the sort to job jump every so often.
