Android may not have the same games catalog as iOS, but it's definitely starting to grow. id -- developers of the DOOM RPG and upcoming Rage for iPhone -- has placed a job listing for an Android programmer, suggesting the team is looking to expand to Google's mobile platform. According to the listing, "id Software is looking for a talented and experienced programmer to help bring our next big Mobile game to the Android space." Presumably, that big game could be Rage, but there's no confirmation.
"The Android programmer is responsible for familiarizing themselves with existing id Mobile engines, bringing Mobile development to Android" and should be intelligent enough to understand John Carmack's Twitter feed. Damn, guess that rules us out.
