Yahoo engineering boss abandons company-saving project for new gigFormer Yahoo engineering director Adam Hyder, who left the company last month, will join job-listings startup Jobvite. At Yahoo, Hyder was best known for leading the Hotjobs engineering team "and is credited for turning around that division," a source tells us. After that feat, Yahoo put Hyder in charge of the application group for the AMP! platform, a dashboard for brand advertisers that's supposed to save Yahoo this fall — if it can find a new name. Our Hyder-friendly source claims he's "bullish" on AMP. That's the politic thing for Hyder to say, of course, but actions speak louder than words. If he's so bullish, why would he leave AMP, unfinished, to a struggling, understaffed team?
