He has also worked at Del Monte Foods. Vranesh, who joined Zynga in 2008, has held roles of chief financial officer and chief accounting officer. He will work with Lee over the next month before leaving the company. To regain its financial footing, Zynga has set in motion a turnaround plan, which includes expanded cost savings, led by Chief Executive Officer Don Mattrick. Shares in Zynga have risen 42 percent since July 1 when the company announced that Mattrick, the former head of Microsoft Corp's Xbox business, would replace co-founder Mark Pincus as its chief executive. Since taking on the top post, Mattrick has cleared out the existing senior management, including former Chief Operating Officer David Ko. Lee, who will also hold the title of chief accounting officer, is the second major hire made by Mattrick.
