SoC = "system on chip" for those who don't know.
I think this hints heavily towards a mobile (smartphone/tablet power envelope) like Nintendo chipset. Though I suspect they are hiring this position to assist with work they have already got going on in Japan (this position is for Redmond).
Also NeoGaf posters point out that AMD has apparently scored a contract deal to make a ARM-based design for two vendors in 2016, but they can't say who those vendors are. Could be Nintendo.
