Getting more direct, the "electronics engineer" position entails working "with the hardware team to conceive, design, evaluate, and produce new types of input, output, and platform hardware." Wait, platform hardware? That sounds an awful lot like the Steam Box rumors we heard earlier this year (rumors that were later semi-shut down).
But don't get your hopes up just yet – just because Valve is experimenting with different types of hardware doesn't mean that it's looking to produce a piece of consumer hardware any time soon. We've reached out to Valve for further clarity, but aren't expecting much beyond silence.
