The body of the messages seem to be (excerpts of) real job postings, but the titles are of course made up by the editor of this satirical site.

These postings are real. I can confirm that I've seen some of these emails in person from Penn.

They look real job/partner postings to me. Wharton is the business school of University of Pennsylvania.

Definitely satirical. At least, that's what the snarky post titles are telling me.
