Two more top executives have quit Uber, the car-hailing app company that has been accused in recent weeks of sexism, theft of intellectual property and cheating regulators. 

Company president Jeff Jones, who was tasked with improving Uber’s reputation and overseeing the bulk of its global operations, resigned just six months after first taking on the role. Jones was appointed to manage Uber’s ride-hailing program, local services, marketing and customer services, having impressed in his previous job as chief marketing officer at retailer Target (TGT). According to tech news site Recode, Jones’ decision to quit was influenced by corporate culture differences. (See also: The Story of Uber.)

"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," he added. 

In a separate statement, Uber’s vice president of maps and business platform also announced his intention to quit the company. Brian McClendon, who joined Uber two years ago from Google (GOOG) to boost the company’s autonomous driving efforts, claimed his departure had nothing to do with Jones’ exit.

The BBC reported on an email CEO Kalanick sent to the staff in which he said, "After we announced our intention to hire a COO, Jeff came to the tough decision that he doesn't see his future at Uber."

Five Top Executives Depart in Less Than a Month

These two high-profile resignations came less than a month after a trio of other top executives left the company. Uber's vice president of product and growth Ed Baker and Charlie Miller, Uber's security researcher, quit earlier this month, shortly before engineering executive Amit Singhal was asked to resign, due to allegations of sexual harassment at his previous job at Alphabet Inc's Google.

Sexual harassment charges have also been made against Uber in recent weeks after a former employee published a blog suggesting that such behavior was widespread and going unpunished at the company. This allegation is now being investigated internally by former U.S. Attorney General Eric Holder.

These potentially damaging accusations add to a number of other scandals currently plaguing the company. Uber is facing a lawsuit from Alphabet Inc's self-driving car division, which accused it of stealing designs for autonomous car technology, and is in trouble with regulators after using its secret technology program Greyball in cities where it is prohibited.
