Don Bradford, an Engineering Manager in charge of Bing's client user experience, has resigned from Microsoft and may move to Yahoo!, according to a tipster. Microsoft is confirming that Bradford has left. Yahoo! didn't respond.
"The move, if it turns out to be true, is interesting for a few reasons. First, Bradford is a long-time, high-profile Softie who has managed teams inside not just the Bing unit, but also Windows Live, Hotmail and MSN. Since July 2008, Bradford was Engineering Manager (Partner level) for Bing UX (user experience) across PC, tablet and server, according to his LinkedIn profile. For the previous three-plus years before that, he was a Group Program Manager for Live Search Communities, where he worked on Live Boards, Ratings and Reviews, QnA and search personalization.
(There's an interesting note in his bio about the Windows Live reorg which resulted in his team being left with "less than 1/3 of the original headcount." The Windows Live organization was moved under President Steven Sinofsky in 2006.)"
