Described in some circles as one of Android open-source gurus, Jean-Baptiste Queru is the latest high-profile Google employee to leave the company.
Queru, also known by his initials JBQ, said on Twitter that he has joined Yahoo as a senior principal engineer working on mobile apps.
The first public indication that the six-year engineering veteran of the Android Open Source Project (AOSP) was reaching the end of his Google tenure came in August.
"There's no point being the maintainer of an operating system that can't boot to the home screen on its flagship device for lack of GPU support," he complained on Google+, referring to the Nexus 7 tablet.
He added that he felt blamed for the problem, which he didn't "have [the] authority to fix" and "had anticipated and escalated more than six months" prior.
AndroidHeadlines.com reported in their story about Queru's departure that Qualcomm had a problem coughing up the documentation for the Nexus 7's open-source drivers, which in turn kept Google from releasing the factory images and driver binaries to developers, with Queru holding as least part of that hot potato despite his claim that he tried to warn them six months before.
Queru is the third major departure of the year for the Android team. Android co-founder Andy Rubin left Android but not Google itself in March, replaced by Chrome leader Sundar Pichai; and Hugo Barra, Android's vice president of product management and a rising public face for Google, departed at the end of last month for Chinese handset maker Xiaomi.
