His departure comes as Bauer looks to offset the tough economic climate by shedding 30 jobs across its commercial and editorial operations. Those cuts were announced in May.
McCabe was associate director of brand solutions, working on its cross-media sales initiative, Bauer2, which has been reined in.
He started his advertising career as a television buyer at Ogilvy & Mather, and before joining Emap in 2005 he spent eight years as Vizeum's head of radio. He joined Emap as planning director of its advertising unit.
McCabe's departure follows that of Bauer2 head Rob Tomalin last year. The unit has been shut as a stand-alone entity and folded into Bauer's commercial development team.
