Jobfox, the “personal branding” site for job seekers that allows them to market themselves to potential employers, says it is doubling its sales staff in response to strong demand.

Based in McLean, Virginia, the company also has sales offices in four major cities, and will be expanding to six more. It is also entering into a deal with Australian jobs site MyCareer.

We’ve previously written about the strategies of Jobfox and a competitor called Trovix. A third company, Jobster, recently showed signs of weakness, replacing its co-founder and CEO with a more experienced exec.

Draper Fisher Jurvetson led the $20 million round, with Menlo Ventures and New Enterprise Associates also participating.
