Research In Motion vice president of BlackBerry Enterprise Server John Vandermay has left the company to assume a new position with Gemcom Software International, the Financial Post reported on Wednesday. Gemcom Software International is a software mining company based in Vancouver. While at RIM, Vandermay led a team of more than 400 software developers and testers working on RIM’s BES, among other projects. Vandermay is not the first executive to leave the Waterloo, Canada-based company in recent history. RIM’s chief marketing officer Keith Pardy left the firm in March. In addition, RIM’s former vice president of digital marketing and media Brian Wallace jumped ship to Samsung in June, shortly before Samsung poached RIM’s former BlackBerry PlayBook senior manager Ryan Biden. In August, RIM’s senior director of global developer relations Mike Kirkup announced that he was leaving the company after a 10-year stint.
