Uber CEO Travis Kalanick is looking for a chief operating officer after a dismal few weeks at the ride-sharing unicorn. He now has to look for a new president.

Recode reported Sunday that Uber president Jeff Jones, who joined the company less than a year ago, is quitting due to "the multiple controversies there," including recent allegations of rampant sexism and sexual harassment at the company.

Jones was poached in August from Target (TGT) , where he served as chief marketing officer. In a blog post, CEO Kalanick said that Jones would become president of Uber's Ridesharing business in part to improve its reputation. Jones previously worked at ad agency Leo Burnett and at Coca-Cola (KO) and Gap (GPS) .

"As we grow, marketing is becoming more and more of a thing, and it was clear we needed a real infusion of talent on that front," Kalanick wrote of hiring Jones. "So we went big."

Despite Jones' best efforts, the public perception of Uber has deteriorated precipitously in just the past few weeks, including controversy and boycotts surrounding Kalanick's participation on President Donald Trump's business advisory council, an internal investigation into Uber's treatment of its female employees, a New York Times expose of its "Greyball" program to circumvent regulators, and a leaked video of Kalanick berating an Uber driver.
