Google‘s CFO Patrick Pichette yesterday announced on his Google+ account that he would be resigning "to spend more time with my [his] family".

He said: "After nearly 7 years as CFO, I will be retiring from Google to spend more time with my family.

"Yeah, I know you’ve heard that line before. We give a lot to our jobs. I certainly did. And while I am not looking for sympathy, I want to share my thought process because so many people struggle to strike the right balance between work and personal life."

The online search giant will now be looking to replace Pichette within six months, the company said in a regulatory filing with the U.S. Securities and Exchange Commission.

Mr Pichette said: "I wish to transition over the coming months but only after we have found a new Googley CFO and help him/her through an orderly transition, which will take some time."

Pichette joined Google in 2008 and has been recognised for his spending discipline and finance control.

"Working at Google is a privilege, nothing less. I have worked with the best of the best, and know that I am leaving Google in great hands. I have made so many friends at Google it’s not funny," he added on his Google+ post.

Last year, Google Chief Business Officer Nikesh Arora left unexpectedly to become vice chairman of Japan’s SoftBank, while Vic Gundotra, the head of Google’s social networking services, left in April 2014.

Google Chief Executive Officer Larry Page in October turned over day-to-day management of major products and services to Senior Vice President Sundar Pichai, freeing him up to focus on bigger-picture issues.
