BuddyPress.org

There is a job board in the dev section. Nothing but a wire now. https://buddypress.org/groups/buddypress-job-board

Emails go out to all those who are members of that group. You could also post a topic here since the job board doesn’t have a forum yet. Post it here and one of the mods will close it after posting. People can contact you through your profile in a PM.
