All good things must come to an end. And when you hit as many high points in your career as George Reyes has, I'm sure the feeling is pretty good. Reyes has been with Google for just over 5 years, and lead Google through their IPO as the search giant's Chief Financial Officer. He previously worked with Eric Schmidt at Sun for a 13 year stint in such roles as Director of Finance and VP-Treasurer.

Reyes has said that he will stay on board until Google finds his successor, and will ensure a smooth transition which should take until about the end of the year.

George is still a young guy, and there are no words yet as to what he is moving on to, if anything. On top of his role at Google, he is a Director of Symantec Corporation, and of BEA Systems.
