If that is what you wanted then be sure you are in for serious business because there are a lot of competitors that have even established themselves up to the point that even prospective participants are the one recommending them, you have no other option than to force your way in couple with your low rank.
What you need need to do, is to be ready to PM every projects coming in asking for a chance to manage something maybe their Twitter or Facebook from there you can graduate it further. Some will ignore you, some will give you the chance.
Another way to go about it is to ask established managers to give you a chance to offer an extra hand and with that, you can get a project to manage by leveling on the experience of co-managing such project before.
