According to a tweet sent out by Ubisoft's Dan Tememe, the publisher is hiring for a "major project" in Montreal.
The position in question is for "project manager."
The tweet by Tememe was posted in French, but the translation goes as this: "Ubisoft is looking for a Project Manager-Construction for a major project."
Here's the page for the position. We've got a feeling the wording on the listing suggests it's for something entirely new.
Ubisoft's Montreal studio are most infamously behind Assassin's Creed, Far Cry and Prince of Persia.
