With WhoPlusYou, job invites will come to you. To control what kinds of jobs you're being invited to, just edit your Opportunity Preferences.
To find this, log in, and click Profile on the left. In your profile, just below your Basic Information, you'll see a section called Opportunity Preferences. Click the pencil icon to edit it.
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!
