Nipoon Malhotra has supported Twitter's brand advertising and search efforts for nearly three years. Now he takes his talent to Pinterest where he will build out the platform's visual experience, which many marketers now are contemplating how to use in campaigns.

"Excited about starting at @Pinterest and the future ahead," Malhotra wrote in a Twitter tweet. "Thanks @twitter for a wonderful time."

Malhotra in July spearheaded efforts to make it easier for advertisers to reach audiences in the moment through event targeting with the help from event calendar, event insights and event activation within Twitter.

At Microsoft, Malhotra focused on Bing and search engine advertising. Aside from leading a team of program managers for Whole Page Ranking, he led Metrics & Ad optimization at Bing, focused on universal and blended search strategies, and supported initiatives leading up to the "Bing it on" campaign.

He also drove up revenue per thousand impressions, creation of the infrastructure, metrics and algorithms for universal search at Bing, and helped create and manage an ecosystem for a large number of teams that create rich content in Bing, according to his LinkedIn profile.

As for a faltering Twitter, Malhotra is the latest employee to exit Twitter following former CEO Dick Costolo's resignation on July 1. Former media chief Gabriel Stricker, credited for turning around the company's reputation, left. Christian Oestlien, former vice president of product, departed for YouTube. Former product director Todd Jackson, which arrived at Twitter through an acquisition, went to Dropbox.
