In addition to the rising tide of tenure-track and post-doc positions recently mentioned here and over on Mills Kelly’s blog, there are at least three excellent senior positions available this year in the digital humanities:
The Breslauer Chair in Bibliography at UCLA
The NINES directorship at the University of Virginia
Dartmouth’s newly endowed chair in the Digital Humanities
I might also add the Director of the Digital Humanities Observatory at the Royal Irish Academy. See:
