Working way above my pay grade, please advise for future switch

I was looking at the hierarchy of grades within my current company and their associated definitions. While reading those, I realised that the work I am doing is what is expected from a grade 4 level above my own. I am grateful for the opportunities. Also, I am in the present company only to gain experience, so no grudges whatsoever. But soon I will need to focus on my financial growth as well, thus I see a switch is on the horizon. In my current company, I am leading and managing a small team apart from my own work, but my grade doesn't reflect that, and I don't think it ever will just in a matter of few months. So when I switch, how do I make sure that my work is the deciding factor for my next position and compensation, and not this company's grade or my YOE? YOE - 2 CTC < 5
