The Bungie Studios page has what looks like two new job entries on it today; one for an Environment Finishing Artist, and one for a Character Animator.
UPDATE: These are most likely old. Louis Wu of HBO let us know that he wrote about the Finishing Artist position last January; we didn't find it because we were looking for the full title 'Environment Finishing Artist'. However, one might assume that because they are still listed on Bungie's page, that the jobs might still be open, even after all this time.
