Unfortunately I don't know much about career pathways in data science. If you're trying to figure out your next move, I would seek out someone who's worked in data science in your area (I say "your area" because they'd give advice better suited to where you are - unless you don't mind relocating). Sit down for coffee (or a Skype session) with this person and ask them all the questions you have. Then I think you'll be able to make fact-based decisions about your next steps. Good luck!
