Early Siri Engineer Departs Apple for GE

One of the last members of the original Siri team has left Apple for General Electric, said two people with knowledge of the move.

Darren Haas, 41 years old, quit a few weeks after another former Siri team member, Steve D’Aurora, decamped for GE.

Political infighting has engulfed Apple’s engineering ranks after the company decided to extend the software platform built by Siri’s team to Apple’s other Internet services such as iCloud and iTunes. At GE, Messrs. Haas and D’Aurora are working on a similar cloud software platform.

Apple acquired Siri in 2010. Earlier this week, the Siri co-founders, who left Apple years ago, unveiled a new virtual assistant, Viv.

Mr. Haas is known in cloud software circles for using Hadoop and Mesos for Siri, helping Apple embrace open-source software for many Internet services. He previously co-founded Change.org.
