It's no news that Valve is working on its own gaming hardware platform so far referred to as Steambox, but its talk has been mostly based on rumors and anecdotal information. The Steambox theory, and the theory that Valve is working on hardware, got cemented by a new job vacancy posted by Valve, which calls for experienced electronics engineers. The posting reads "For years Valve has been all about writing software that provides great gameplay experiences. Now we're developing hardware to enhance those experiences." The skillset asked for in the posting fills a lot of holes in the Steambox theory. It requires engineers to be proficient with prototyping, system-level design, embedded systems, high-speed serial interfaces, circuit simulation, etc., with a much more juicy "recommended" skillset requirement covering areas such as board layout, ARM/x86 system design, power/thermal management, RF and antennas, etc., basically everything a company out to design a game console would seek in its new engineers.
