Simply Hired has added another social network to its growing list of customers. The job aggregator will now power Plaxo. This comes on top of recent deals we reported on with USNews.com, MySpace, LinkedIn, CNET, and Fox Television Network.

Jobs on Plaxo can be shared, re-shared, and commented upon, like any other shared content on Plaxo. In addition, Plaxo members will occasionally see targeted job listings in their Pulse stream (it’s based on the professional info the Plaxo member inputs into his or her profile).

Simply Hired has a database of 5 million listings. The company’s new Plaxo portal is at http://jobs.plaxo.com/.
