For startups I linked another poster to: http://swedishstartupspace.com/job-board/

and "try visiting STHLM Tech Meetup's bar mingle after each event: http://www.meetup.com/STHLM-Tech-Meetup/ "

But also check out Linkedin and monster and such for corporate jobs. I believe most are up there. Otherwise try to network with people working in the big corps, that is usually the best way to get in.
