Last year, Apple began marketing its iPod touch as the “funnest iPod ever,” a nod to the significant popularity of the game applications available on the iPhone/iPod touch App Store. Games designed by third-party developers have been big sellers for the platform, and now Apple itself looks like it wants in on more of the fun — it’s advertising for an in-house game developer. The candidate must “help design and implement interactive multimedia experiences on the iPhone and iPod touch” and be a creative thinker who can “contribute and comment on the design process.”
