garg55Parag Garg, who was hired as a technology adviser to Microsoft co-founder Paul Allen, has left the job after just four months, reports Reuters.

It’s unclear why Garg left Allen’s Vulcan Inc. so soon after he was hired. We’ve reached out to both Garg and Vulcan for comment, and we’ll update this post if we hear back.

Garg previously worked as a product architect at Amazon.com, and according to his LinkedIn bio was the inspiration behind the newly-release Amazon Fire TV set-top box.

“I wasn’t happy to leave, but Paul Allen doesn’t hire a tech advisor every day,” Garg told GeekWire of his decision to leave Amazon late last year.

Before Amazon, Garg worked at Microsoft, on projects including the Xbox One, the unreleased Courier tablet and Windows Embedded.
