Academia is a circle. Normally you need an outstanding work during your PhD and Post-PhD to get a university position. Without these, the possibility of getting an entry-level long-term (not tenure) position in the university is near to 0, let alone without an undergraduate degree.
But your situation won't prevent you from doing some serious research work yourself, in an UNUSUAL way. I'd suggest you give up seeking any normal recognition in the academia circle (like a long-term position or a title) until you've achieved something obviously awesome.You have to understand it's hard for people to view you as an exception unless they are surprised by what you've achieved. People would doubt, if this guy is awesome enough, then an undergraduate and PhD degree are like a snap for him, why he didn't just get the degree.
If you insist on not pursuing a degree and go for an usual way, that would be very hard. But maybe you are indeed an exception. Wish you good luck!
