Just a few weeks after the launch of iOS 7, Apple's Vice President of Engineering for iOS Henri Lamiraux has retired and left the company, 9to5 Mac reports. A quick look at his Facebook page confirms the news. Lamiraux, who joined Apple in 1990, worked closely with one-time iOS lead Scott Forstall on the original iPhone, and has his name on a number of important patents including visual voicemail. More recently, he worked under Craig Federighi, who's in charge of software more broadly at Apple.

Lamiraux planned to retire after Apple shipped iOS 7, its biggest mobile revamp ever, 9to5 Mac reports. His departure will be felt within the company, but also outside it. Lamiraux frequently led education sessions at WWDC, Apple's yearly convention for developers. It's not clear who will replace him as Apple's lead iOS engineer.
