I've been finding research topics for a while, but I don't really know how. I read some research and sometimes work on high-level things, and sometimes I fiddle with low-level toy problems (one of my hobbies lately has been writing SIMD algorithms for some reason). Some side projects have gotten fairly far along where I've alternated between setting a goal and researching the means to achieve it.
