Apple’s vice president of Siri engineering, Mike Rockwell, is reportedly considering stepping down from his position or leaving the company altogether in 2027. According to Bloomberg’s Mark Gurman, Rockwell continues to weigh his future at Apple despite successfully leading the development of the company’s revamped Siri AI assistant.
In his latest Power On newsletter, Gurman described Rockwell’s potential departure as a major setback for Apple, particularly after the executive helped bring the long-delayed Siri overhaul to market.
Mike Rockwell, who created the Vision Pro headset in addition to leading the development of Siri AI, continues to seriously consider stepping down.
Rockwell’s Future at Apple Remains Uncertain
Rockwell previously led Apple’s Vision Products Group, where he oversaw the development of the Vision Pro headset. However, Apple appointed him to lead Siri engineering in March 2025 after growing concerns about delays in its artificial intelligence development.

The executive subsequently helped deliver the new Siri AI experience in iOS 27, which introduced more natural conversations, improved contextual understanding, and deeper integration across Apple’s ecosystem.
Reports about his potential departure first surfaced in April, when Rockwell was said to be considering leaving Apple or moving into an advisory role.
Who Could Replace Mike Rockwell?
If Rockwell steps down, Apple could redistribute his responsibilities between Amar Subramanya and Sebastien Marineau, according to Gurman.
Subramanya, a former Google executive, joined Apple in 2025 to strengthen its AI development efforts. Meanwhile, Marineau works under software engineering chief Craig Federighi and oversees teams responsible for integrating artificial intelligence into iOS.
The leadership uncertainty comes as Apple CEO John Ternus reportedly pushes Federighi to accelerate the company’s AI roadmap, including plans to develop a more autonomous Siri capable of completing complex tasks with less user involvement.
For now, Apple has made no official announcement regarding Rockwell’s future, and his potential departure remains under consideration.
