Apple is moving forward on bringing Thunderbolt to iOS devices, new job listings indicate. The company is currently searching for a Thunderbolt firmware/software engineer, whose role will be to "develop and maintain firmware for embedded controllers for Thunderbolt products," along with creating "corresponding Mac OS X tool and utility applications such as updaters and exercisers." Crucially, Apple is hoping for a person experienced with ARM processors; the company's A4 and A5 chips -- used in the iPhone, iPod touch, iPad and Apple TV -- are ARM-based designs.
