Perimeter Institute has begun its annual search for postdocs in various fields in the foundations of theoretical physics. If you are interested in getting a postdoctoral fellowship at Perimeter then please apply on their website:

The deadline is November 15th. Apparently, they will consider applications after that date but chances are reduced, I am told.
