BlackBerry maker Research In Motion (RIM) is hiring a software developer with experience for building applications for Apple's iPhone and iPad, according to a job posting on its LinkedIn page. The posting suggests the company may be interested in adapting some of its proprietary applications for use on Apple's iOS operating system.

It has been speculated that RIM could make its BlackBerry Messenger (BBM) instant messaging service available on rival platforms including Android and Apple.

According to the LinkedIn post, the candidate would "create exciting enterprise applications for distribution on the iOS platform" and would be "capable of architecting, designing, developing and testing complex applications for iPhone and iPad devices."

However, the Waterloo-based company clarified that the listing is related to RIM?s upcoming BlackBerry Mobile Fusion platform, which will allow IT administrators to manage not just BlackBerry and PlayBook devices, but those running Android and iOS operating systems as well.
