A new job posting discovered today suggests that the role of a Software Engineer will be responsible for optimising and tuning the game resource system for the PS VITA and interfacing the game engine with several parts of the VITA OS.
Interestingly, the role also indicates some kind of cross-platform play. Implementing interoperation between PS3 and the VITA is also listed as a responsibility.
