Uber president Jeff Jones has stepped down from the job less than a year after he was appointed, telling Recode website on Sunday his "beliefs and approach to leadership" were "inconsistent" with what he had experienced at Uber.
The departure of the company's number two in charge comes as Uber reels from multiple scandals, including accusations of sexual harassment.
"It is now clear ... that the beliefs and approach to leadership that have guided my career are inconsistent with what I saw and experienced at Uber," Jones said.
Recode quoted sources as saying that the situation at Uber was more problematic than Jones, who was hired with much fanfare, had realized.
In a note to staff, boss Travis Kalanick suggested that Jones had left because he was upset that plans had been announced to hire another executive who would have outranked him.
"After we announced our intention to hire a COO (chief operating officer), Jeff came to the tough decision that he doesn't see his future at Uber," he wrote.
Google sister company Waymo is currently suing Uber for allegedly stealing its self-driving car technology and infringing its patents.
Kalanick also was criticized recently when he was filmed shouting at an Uber driver, afterwards admitting that he needed to "grow up" and get "leadership help." He later announced the COO appointment.
Uber also is facing claims of a culture of sexual harrassment after a blog post written by former engineer Susan J Fowler last month detailed multiple instances she said the company had failed to deal with.
