Most game developer websites have a spot somewhere near the bottom in tiny two point type advertising the fact that they're hiring. Others post on job boards, or even major forums for their respective games. Recently, NCsoft took a slightly more aggressive approach by planting their help-wanted sign right on their front page. Others have done this recently as well, including Blizzard. Don't be afraid to check out the job listings on your favorite MMO's website for the possibility to get yourself started on the track to developing games, too.
