Following Tumri's recent hire of Calvin Lui as president and CEO, Rajaram's addition is another step in Tumri's aggressive expansion plans, according to the Mountain View, Calif.-based company.
Rajaram most recently served as product management director for Google AdSense. He worked at Google from January 2003 to November 2007, helped conceive and crystallize AdSense in early 2003, and played a key role from its launch to its growth into a multibillion-dollar product line.
He also helped drive a number of Google's acquisitions, including DoubleClick, AdScape, and dMarc. Earlier in his career, Rajaram worked as a technical architect at Juno Online, where he developed the back-end advertising system that drove much of Juno's revenues and helped it go public in 1999.
