It’s the first of September and Apple’s new China and People VPs have started their new roles at the company. Both Deirdre O’Brien and Isabel Ge Mahe have joined Apple’s Leadership page for their respective roles as Vice President of People and Vice President and Managing Director of Greater China. Siri has also moved from Eddy Cue to Craig Federighi who oversees iOS and macOS.

Apple announced O’Brien’s promotion to VP of People back in July. The newly created position oversees both Apple HR and Apple University, the company’s learning program. Ge Mahe’s promotion to VP and Managing Director of Greater China was also first announced in July, making her the point person for China activity, reporting to CEO Tim Cook and COO Jeff Williams.

O’Brien also reports directly to Tim Cook, although we heard from sources familiar with the change in July that Joel Podolny who serves as Apple University Dean would not change job titles. It’s unclear if that’s still the case, however, as Podolny’s profile was removed from Apple’s Leadership page overnight as O’Brien and Ge Mahe were added.

O’Brien’s new VP of People position primarily takes HR responsibilities from Denise Young Smith who moved to VP of Inclusion and Diversity this summer, with CFO Luca Maestri temporarily filling the position before today.

We’ll update if we learn more about Podolny’s role at the company. [Update: We’re still hearing that Podolny’s role at Apple has not changed despite the update in how Leadership is presented online.]

Here’s Deirdre O’Brien’s new profile:
