I work FT and so does DH. I always helped him find a job...you could be helpful OP. Look at job sites, contacts at different companies, maybe help him come up with a target list and make sure he's got a good LinkedIn profile. I'm a retained executive recruiter and we source candidates right off of LinkedIn. In addition to a profile, make sure he joins all applicable LinkedIn groups (go to "groups directory" on LinkedIn to find the list).
Good luck -- it's never fun looking for a job. I don't do tech searches, but you could google recruiters who do...don't sit around and fret...try to help.
