My team is looking for version control nerds for some developer tools work. Pittsburgh and NYC are the locations we can do for now. Sadly, I can't go into much detail about the specifics of what we're doing, but we're digging deep into Git and Mercurial, working on building fast servers and some clever features on top of both systems.
My email is in my profile if you want to know more - experience with the guts of either git or hg is very desirable.
