If you're in Europe, the following companies always seem to be growing their (already large) Perl teams:

http://www.net-a-porter.com/ http://www.lovefilm.com/ http://www.photobox.co.uk/ http://www.booking.com/

Send me a CV and I can make sure it gets to the right people.

If you want to work with Perl, http://jobs.perl.org/ is always a good place to look.

I know of ShutterStock (NYC) and Aruba Networks (Sunnyvale) (AirWave team only). AirWave was interesting, but I don't know what they're doing over there anymore since I left and there's been some management shakeups (some of which may have been positive). Shutterstock is where a former coworker went; he says it's snazzy and they just filed for IPO.

I also hear Blekko is all Perl (it's the dmoz directory-people making a search engine. it's got social-search-related features, too, or something like that.) Apparently they have some fancy sophisticated technology for their backend systems (store big bitfield indexes on SSDs with a disk-backed store for the rest, spread across dozens of nodes, etc.) But I don't know anyone actually working there.

If you have the initiative you can look up their job applications yourself :P

DuckDuckGo is Perl.

Best Practical in Somerville, MA is looking for perl hackers: http://bestpractical.com/about/jobs.html#hacker

(I've been using their perl/mason based ticketing system, RT, for 5 years)

If you're in Los Angeles, check out http://perl.la/. I know my employer (oversee.net) is hiring, and I'm pretty sure many of the others on there are as well.
