Apple has announced that its Senior VP of Hardware Engineering, Bob Mansfield, will retire and over the course of the next few months transfer his role to Dan Riccio. Mansfield is credited with leading the Mac engineering team since 2005 and took on a more visible role as an exec during the reshuffling in 2008. He’s also mentioned as leading iPhone and iPod engineering since 2010 (when he took over the role from Mark Papermaster in a move curiously timed around those antenna troubles) and the iPad since it began. He’d been with Apple since 1999 when it acquired his previous employer, Raycer Graphics, and most recently popped up on our radar earlier this year while integrating another acquisition, flash memory maker Anobit. If you’d like to get familiar with his replacement, Dan Riccio is currently vice president of iPad hardware engineering. Check the press release after the break for a few more details on both individuals, there’s no word on Mansfield’s post-retirement plans.
