Microsoft is experiencing yet another significant executive departure as Julia Liuson, head of its developer division (DevDiv) for the past 12 years, resigns after a 34-year tenure with the company.

Liuson will remain in her role until June before transitioning to an advisory capacity under Microsoft CoreAI chief Jay Parikh. Her departure follows recent high-profile exits including former Xbox boss Phil Spencer and hardware division leader Rajesh Jha.

“I’ve been thinking about this for a while, and in January I shared with Satya [Nadella] and Jay [Parikh] that the timing feels right for me to take this step,” Liuson said in an internal memo. “I am proud of how DevDiv is recognized as one of the most customer-obsessed teams.”

Her exit comes under a broader period of shake-ups at Microsoft, including the acquisition of GitHub and changes in leadership roles across various divisions. With Liuson stepping aside, it remains to be seen who will take over her responsibilities.
