Tag jobs with required skills, interests & technologies, show jobs by tag using shortcodes and add tag filtering to the main jobs shortcode.
The Job Tags add-on lets you tag your job listings with things such as required skills, technologies the applicant should be adept in, terms related to your listing and more.

These tags get displayed on your job listing, and can also be listed in tag cloud format using a simple shortcode. That’s as easy as adding [job_tagcloud] to your content.
Job seekers will be able to filter jobs by tags they are interested in via a tag cloud shown within the [jobs] shortcode.

Multiple tags can be toggled off/on providing an advanced search.
