Bob Mansfield, senior vice president of hardware engineering at Apple and one of the driving forces behind the Mac, iPhone and iPad product lines, will depart the company for retirement.
Mansfield, who reports to CEO Tim Cook, joined Apple in 1999 through its acquisition of Raycer Graphics. He has been in charge of Mac engineering since 2005 and iPad engineering from the product's beginnings.
In 2010, Mansfield took over iPhone engineering after Mark Papermaster, former longtime IBM executive and current CTO at AMD, stepped down in the wake of the iPhone 4 "Antennagate" issue.
"Bob has been an instrumental part of our executive team, leading the hardware engineering organisation and overseeing the team that has delivered dozens of breakthrough products over the years," Cook said in a statement.
Mansfield will be handing off his day-to-day duties to Dan Riccio, vice president of iPad hardware engineering, over the "next several months," Apple said in a statement.
Riccio joined Apple in 1998 as vice president of product design and in April 2010 was named vice president of Apple's iPad division. Before joining Apple, Riccio spent a year at Compaq as a mechanical engineering manager, according to his LinkedIn profile.
In Apple's fiscal second quarter, the company sold 35.1 million iPhones and 11.8 million iPads, representing year-over-year growth of 88 percent and 151 percent, respectively. Mac sales rose 7 percent during the quarter to 4 million units.
