How to go from BDR/SDR to SE?

I just started out in sales not too long ago, and am working for a startup. We currently don't have a SE, but I've expressed my interest to leadership in developing into the SE role, and they are supportive of it. To get straight to the point, what can I do, other than my job 😅, to lead me (and anyone else) a BDR into an SE role ? Looking forward to the replies.
