Y ouTube confirmed on Tuesday that Steve Chen, a co-founder and most recently YouTube’s chief technology officer, was no longer working at the company. Mr. Chen left some time ago to work on unspecified engineering projects at its parent, Google.

In an e-mail, YouTube spokesman Ricard Reyes said: “Steve shifted his focus to help with some Google engineering projects. He’s still involved with YouTube and invested in its success.”

Mr. Chen co-founded YouTube in 2005 with Chad Hurley, who remains chief executive, and Jawed Karim who left the company early on to attend graduate school. Little more than a year later, Google purchased YouTube for $1.65 billion, turning the three founders into millionaires many times over. Mr Hurley’s holdings were worth more than $345 million in February of 2007, Mr. Chen’s more than $326 million, and Mr. Karim’s more than $64 million.

Mr. Chen’s move, which was first reported by the industry blog AllThingsD, was never officially announced. In fact, the company’s Web site still lists him as chief technology officer.
