Twitter on Thursday updated its website to reflect that it has appointed a new chief technology officer, Parag Agrawal. He takes the position most recently held by Adam Messinger, who left in late 2016.
The appointment was announced internally in October, during a quarter when Twitter managed to produce a net profit for the first time. Meanwhile, Agrawal came to the top rungs of Twitter's corporate leadership just before the company's operating chief, Anthony Noto, announced that he would leave.
"In his capacity as CTO, he's focused on scaling a cohesive machine learning and AI approach across our consumer and revenue product and infrastructure teams," a Twitter spokesman told CNBC.
Facebook, Google, Microsoft and other technology companies also use AI to enhance various parts of consumer services, as well as internal tools.
This isn't the first time Twitter went some time without a CTO. Its first CTO, Greg Pass, arrived in 2008 after Twitter bought Summize and left in May 2011. Messinger, a former Oracle executive, joined Twitter in November 2011 but only took over as CTO in March 2013.
Twitter stock is up 45 percent since the beginning of the year.
