With WhoPlusYou, job invites will come to you. To control what kinds of jobs you're being invited to, just edit your Job Preferences.
To find this, log in, and click Jobs under the Apps menu:
Now from the menu on the left, click Job Preferences:
Here, you can specify what kind of jobs you're interested in. Keep in mind, this will exclude you from being invited to jobs that don't match these requirements in future!
