Research Scientist. If you wan to do a more research elated role, I'd suggest you find one. They're certainly out there, just talk to companies who are hiring (see the NeurIPS sponsor's page). I can't tell you how hard/easy it will be to get in if you don't have any recent, relevant publications in the area, though. I'd expect that at least early-stage startups might not care, but you won't have time to do research there, either.
