Shige Honjo, a veteran hardware chief at Nest, and Scott Mullins, a senior engineering manager, are leaving the company, according to multiple sources.
Honjo, the director of hardware design and engineering, will depart at the end of May. Mullins is shifting over to Google to work on the next iteration of its Glass wearable, dubbed Project Aura internally. (He'll continue to work for Nest CEO Tony Fadell, who runs Aura independently of Nest.)
Both Honjo and Mullins reported to Nest's number two exec, VP Matt Rogers. While they are key leaders at the company, the pair are not on the senior team that reports into Fadell.
Still their exit comes amid a steady stream of departures from the connected-device unit under Google parent Alphabet, as pressure mounts on Nest to improve its sales targets and right its increasingly rancorous culture.
A Nest representative declined to comment.
