The company differentiates itself from other recruitment agencies by promoting its social networking aspect.
Wag Ed consultant Ged Carroll, who is running the account, said: ‘Jobster has previously done some UK PR, but now wants to increase its profile prior to a planned UK office opening.'
He added: ‘We will target business and HR titles, and handle some consumer PR to target jobseekers.' Wag Ed already holds the account in the US.
Entrepreneur Jason Goldberg launched Jobster two years ago. Microsoft is among the 120,000 employers that use the site.
Goldberg has secured a further $18m in funding from the VC arm of publisher Reed Elsevier.
Jobster now plans to expand into India and China.
