His previous experience also included positions at Macromedia (Vice President of Product Marketing), FirePower Systems, Inc.

At Apple, Schiller was instrumental in the formation and marketing of iMac, iBook, PowerBook G4, iPod, Mac OS X, and subsequent products.
Schiller frequently participated in a supporting role in keynote presentations given by Steve Jobs, usually presenting new products, like the iPhone and the iPad. During Steve Jobs's medical leave of absence, he presented numerous keynote presentations himself (with supporting segments by other Apple staff), including Apple's last appearance at IDG's Macworld trade show on January 6, 2009 and the WWDC keynote on June 8, 2009. Both presentations, held in San Francisco, were typically presented by Jobs himself. Among the things announced at these events were the updated MacBook Pro lines, the iPhone 3GS, new versions of the iLife and iWork suites as well as pricing and DRM changes to the iTunes Store. As of today, Schiller is the main person to host the events.
