Micro-blogging website Twitter has hired Indian-born Sriram Krishnan, a former top executive from Facebook and Snap, as its Senior Director of Product.
"I'm going to be joining Twitter and become a part of #theflock to work with the fantastic product team there," Krishnan tweeted.
A well-known product executive around Silicon Valley, Krishnan has primarily focused on ad technology.
"So so so so so so excited to have you Sriram! Welcome home," tweeted Twitter CEO Jack Dorsey late on Monday.
"At Facebook, he helped build the company's ad network, Audience Network; at Snap, he helped build out the company's ads API," Recode reported on Tuesday.
Starting October 2, he will be responsible for core features inside the main app, including timeline, direct messaging and search.
Krishnan will be reporting to Twitterâ€™s head of product Keith Coleman, who joined Twitter last December to run the companyâ€™s core app. Krishnan will also be taking over some of Colemanâ€™s responsibilities.
Krishnan left Facebook in February 2016 to help lead advertising efforts at Snapchat's parent company Snap. He quit Snap in February.
At Facebook, he led "Facebook Audience Network" to take on Google.
This comes at a time when Twitter is struggling to grow having added zero users since first quarter and revenues decreasing 5% to $574 million in revenue in the second quarter this year.
Its co-founder Biz Stone, who left the company in 2011, also rejoined the company as a full-time employee with the focus to guide company culture and shape the experience internally.
