Jeff Jones resigned as president of Uber on Sunday, adding to the list of troubles the ride-hailing service has recently struggled with. His exit is reportedly related to the sexual harassment and sexism allegations against Uber, according to Recode.

"I joined Uber because of its mission, and the challenge to build global capabilities that would help the company mature and thrive long term," Jones said in a statement to Reuters. "It is now clear, however, that the beliefs and approach to leadership that have guided my career are inconsistent with what I saw and experienced at Uber, and I can no longer continue as president of the ride sharing business."

Jones worked at Uber for nearly seven months. Previously he'd been a CMO at Target, and he was hired to help Uber with its floundering image. However, sources say he found the situation at Uber more problematic than he initially realized. Jones resigned as Uber CEO Travis Kalanick launched a search for a chief operations officer earlier this month.

"After we announced our intention to hire a COO, Jeff came to the tough decision that he doesn't see his future at Uber," Kalanick said in a note to Uber staff. "It is unfortunate that this was announced through the press but I thought it was important to send all of you an email before providing comment publicly."

Jones isn't the only one who quit recently. Brian McClendon, the vice president of maps and business platform, also plans to leave Uber at the end of the month. However, McClendon is splitting amicably from the company and will act as an adviser, according to The New York Times.

Jones's announcement comes as the company has been juggling mishaps and controversies, including the sexual harassment allegations that reportedly contributed to his departure from Uber. What's more, Uber has also come under fire for Kalanick's treatment of a company driver and the company's use of technology to evade regulators.
