WP Job Manager is a lightweight job listing plugin for adding job-board like functionality to your WordPress site. Being shortcode based, it can work with any theme (given a bit of CSS styling) and is really simple to setup.
FEATURES

Searchable & filterable ajax powered job listings added to your pages via shortcodes.
Frontend forms for guests and registered users to submit & manage job listings.
Allow job listers to preview their listing before it goes live. The preview matches the appearance of a live job listing.
Each listing can be tied to an email or website address so that job seekers can apply to the jobs.
Searches also display RSS links to allow job seekers to be alerted to new jobs matching their search.
Allow logged in employers to view, edit, mark filled, or delete their active job listings.
