I'm in the same boat and there aren't many. Startup founder or first-wave employee is the most likely option. I've done that several times. The larger the company, the more cookie-cutter the roles and titles.
Another option is to find a cookie-cutter role that fits your interests. For me that means "embedded software engineer", where all of my experience is relevant. I'm definitely all-tech and no-management now though.
Yet another option is consulting/contracting/freelancing. You need a good network for that. I haven't done this. Preparing to potentially do it in a few years after I have a larger nest egg.
