The Linux Jobs Database lists jobs that require Linux specific skills and experience. If you are looking for people with Linux skills then you can add a new job and have it listed here. Listings are currently offered free of charge as a service to the Linux Community. You can also search for specific skills at the OpenSkills website.
Current jobs, listed in reverse chronological order (newest at the top) or join the Jobs Mailing List (jobs@lists.linux.org.au). An alternative way to advertise your Linux and Open Source skills for work is to register at OpenSkills, which is an optionally paid membership service.
