Zenimax, the parent company of Bethesda Game Studios, has started hiring for a next-generation project and are looking for "experienced programmers to work on cutting-edge technology."
It appears that following the release of The Elder Scrolls V: Skyrim, Bethesda are now looking to turn their attentions to the next generation of consoles, which is expected to be announced at some point this year.
The job listing stated that the hiree would be working on an unnanounced game, and that they should be well versed in DirectX 11, suggesting that the game will also be developed with the PC in mind.
Bethesda aren't known to develop too many franchises internally, so this could point towards a new game in the Fallout franchise, or another property into The Elder Scrolls franchise.
