BioWare has proven its a master of single-player RPGs, but a new job posting on EA's official site indicates that the developer's Montreal-based office is preparing to branch out into multiplayer, possibly with the third installment of Mass Effect.

The posting (which you can view here) is for a multiplayer programmer at BioWare's relatively new Montreal studio. While the first two Mass Effect titles were developed at BioWare's Edmonton offices, it wouldn't be the first time that another studio has handled a major title's multiplayer component.

Initially, the intro paragraph of the posting singled out Mass Effect as one of BioWare Montreal's projects, but now simply reads "We are working on BioWare's top franchises."  The posting also points out that experience with the Unreal engine is a plus, which also happens to be the tech under Mass Effect's hood. While none of these elements are conclusive evidence, it is still exciting to speculate about the direction of BioWare's epic sci-fi franchise.
