I've won plenty of games now and i usually play with my brother so me and him are usually jump master but neither of us got the badge on any of our champions.

It's probably bugged. I know I've won plenty of games where I started as Jumpmaster and I also do not have the badge. And quite a few of those wins as Jumpmaster involved me never being downed at all, so I know that has nothing to do with it.
It's not a very impressive badge anyway though. It's basically just a badge saying you won 1 game where you also won the 1/3 chance lottery of being Jumpmaster and not relinquishing it.
