According to a job posting (http://macte.ch/jQkh5), Apple plans to hire a signal integrity and power manager in a group that develops SOCs [system-on-chips] that will be used in Apple mobile devices.
“The Signal Integrity Manager needs to have extensive experience in mobile product board designs, SI expertise in Serial links (such as DisplayPort) as well as parallel bus standards (such as LPDDR2 interface), and power integrity at package level and as well as board level,” says Apple.

SOC refers to integrating all components of a computer or other electronic system into a single integrated circuit (IC) chip. It may contain digital, analog, mixed-signal, and often radio-frequency functions – all on a single chip substrate.
