Apple is searching for two power engineers to "help improve the performance and battery life of OS X," according to a Twitter post
by OS X team member Anthony Chivetta. Both jobs will be based at the company's Cupertino headquarters. Listings ask one of the engineers to "design the latest tools to automate the collection of power information," and the other to improve the power efficiency of both OS X and its included apps.
In June 2013, the MacBook Air line got a major battery performance boost through an upgrade to Intel's Haswell platform. The MacBook Pro line should follow suit later this year. OS X Mavericks -- expected to ship within weeks -- makes power efficiency a key feature
. The OS reduces the processor consumption of inactive apps and Safari tabs, and is also said to be more efficient when playing iTunes video.
