Hi myhero,
I have yet to encounter a general plugin for this purpose that works specifically with Jobroller. This is probably because Jobroller uses some specialized functions and including custom post type.
However, a coder member has offered a similar plugin that you may check here

Anyway, I am moving this thread to the Plugins Exchange section for community support.
Cheers.
