Twitter Inc. just added another big name to its executive ranks. On Wednesday, the company named Google Chief Business Officer Omid Kordestani as its executive chairman. Kordestani played a key role in building Google as a business and has served in a variety of roles at the search giant since 1999.

Kordestani’s appointment is the latest of many moves made by Twitter a week after Jack Dorsey was appointed as chief executive officer. Dorsey took to the social media site to make the announcement.

Before Twitter and Google, Kordestani also held roles at Hewlett-Packard and Internet pioneer Netscape Communications. He also took to the microblogging website to express his excitement at assuming the new role.

But his appointment also comes a day after Twitter announced its plans to cut 336 positions, about 8 percent of its workforce. “This isn't easy,” wrote Dorsey in a companywide email. “But it is right. The world needs a strong Twitter, and this is another step to get there.”

While jobs were cut across all departments, the product and engineering teams had the “most significant structural changes,” Dorsey added in his email. As part of the restructuring, Twitter also noted that it expects its revenue for the third quarter to land “at or above” the high end of its previous guidance of $545 million to $560 million, according to SEC filings.
