For the second time in the past year, Jon McCormack has decided to leave Amazon.

This time, McCormack, who was most recently the CTO in charge of devices, including Amazon’s Kindle and Fire TV, has joined Google, according to Re/Code.

Amazon did not reply to an email seeking comment, however, Re/Code confirmed McCormack’s new position with Google. Additionally, McCormack advertised his move today after posting a photo publicly on Facebook of the Google Android robot, saying “Well hello there Android…” In a separate Facebook post, he said he left his job at Amazon on Aug. 21.

On LinkedIn, McCormack confirmed he is joining the company’s advanced technologies and products division, which he describes as a “band of pirates” making the future.

His departure is particularly noteworthy because it is the second time he has left Amazon in the past year. The first time, he left his job as VP of Kindle Software in December for a job at Yahoo. For two months, he was Yahoo’s VP of engineering, before he returned to Amazon in March, where he was promoted to CTO of Amazon Devices. His latest departure comes just six months after rejoining Amazon.

Google’s advanced division is headed up by Regina Dugan, the former head of the Pentagon’s research group, DARPA, and is tackling such project as augmented reality and wearable tech. Re/Code reports that most recently McCormack was reporting to David Limp, who runs the entire devices division at Amazon.

In April, Silicon Valley Magazine quoted the Australian native, who is living in Los Altos, Calif., as saying “I’m not interested in just taking ‘a job’,” he said. “It has to be a job that sort of fits with what I want out of life.” Most of the story is about The Kilgoris Project, a non profit he started with his wife to educate and feed the children of southwest Kenya.

There’s no clues as to why McCormack decided to leave Amazon after rejoining the Seattle retailer for such a sort period of time, but it doesn’t bode well for the company, which is trying to constantly push the boundaries of its comfort zone with mixed results. For instance, while the Fire Phone was received poorly by customers, its Echo Bluetooth speaker has done surprisingly well.
