Jobs are also posted to the all members mailing list.
To submit a position, send it to jobs@cisco-alumni.org.

There are about 1100 people on the list. If you are looking for any specific demographics, skills, or talents to help you decide whether the group is worth targeting, let me know and I can run the search to help focus your query.
