He replaces Cindy McCaffrey, who stepped down as VP of corporate marketing late last year. His will be the top communications post.
Steve Langdon, senior manager of corporate PR, confirmed that Senor had joined the company, but declined to provide further information.
Senor was not available for comment.
Speculation in Silicon Valley PR circles was that Google had been looking to make an unconventional hire for the position.
In addition to his role as spokesman in Iraq, Senor was a senior advisor to L. Paul Bremer, administrator of the Coalition Provisional Authority (CPA). Senor's post was dissolved, along with the CPA, after the US transferred power to an Iraqi government in June of last year.
During Operation Iraqi Freedom, Senor served as director of the coalition information center, based in Qatar. He has also served as a legislative aide, press secretary, and communications director for former Sen. Spencer Abraham (R-MI).
Senor joins the company at a time when competition in the search space is growing fierce. Microsoft and Yahoo are looking to challenge Google's dominance, and search companies are adding new functionality to distinguish their services, from hotel listings to search software for mobile phones.
