McCulloch, who has served as head of Xbox Live for almost three years, said he would announce his next career move soon.
Prior to overseeing Xbox Live, McCulloch held a variety of roles at Microsoft including head of mixed reality for Xbox, HoloLens studio manager, and Microsoft Game Studios portfolio manager for all first-party Kinect titles.
“After 15 years at XBOX, I announced today that I would be leaving,” McCulloch wrote. “I made so many friends, learned so much and truly had a blast!
“I’m extremely excited about the next opportunity in my career and I will be announcing that very soon, you all will be pumped! 😉 Thank you!”
Microsoft also recently announced record engagement figures for gaming services including Xbox Live and Xbox Game Pass.
Xbox Live active users approached 90 million and Xbox Game Pass subscribers topped 10 million during Microsoft’s third financial quarter ended in March 2020.
Mike Ybarra, formerly corporate vice president of Xbox Live, Xbox Game Pass and Mixer, left Microsoft to become Blizzard GM in October 2019 after 20 years with the company.
