Peter Russell-Clarke, who appeared on many Apple patents over the years, and one of Apple Inc.’s last remaining senior industrial designers from the Jony Ive era, has stepped down after nearly 20 years at the company.

The executive worked on hardware design for Apple’s main products and helped craft the look of its headquarters and retail stores. Russell-Clarke, who left the iPhone maker in October, is now joining space technology company Vast as an adviser. He will help the startup build its own industrial design team, Vast said in a statement Monday.

The move represents a changing of the guard for Apple’s vaunted design department. Nearly all of the roughly two dozen core designers who worked under Ive have now left the company. The work of Ive and his colleagues helped established the Apple aesthetic — clean lines and intuitive interfaces — that helped make the iMac, iPhone and iPad into hits. BNN Bloomberg
