RSS feed only jobs available

How do I get just the jobs that are available and not all jobs posted via the RSS feed.

This is what I am using at the moment but it lists also jobs that have been fulfilled.

http://jobs.sebs-studio.com/feed/?post_type=job_listing

I only want jobs listed that have not been fulfilled.

Is this possible?

Please let me know when you can.

Thanks.

Seb
