Uber Technologie Inc.'s president Jeff Jones quit, saying that his beliefs and approach to leadership have been different from Uber's.
Jones joined the San Francisco company seven months ago in an effort to soften Uber's often abrasive image.
"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.
"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. Jones wished the "thousands of amazing people at the company" well.
Uber's vice president of maps and business platform, Brian McClendon, said separately he plans to leave the company at the end of the month to explore politics.
Last month, engineering executive Amit Singhal was asked to resign due to a sexual harassment allegation stemming from his previous job at Alphabet 's Google.
A former Uber employee last month published a blog post describing a workplace where sexual harassment was common and went unpunished.
Earlier this month Uber confirmed it had used a secret technology program dubbed "Greyball," which effectively changes the app view for specific riders, to evade authorities in cities where the service has been banned. Uber has since prohibited the use of Greyball to target local regulators.
Uber is also facing a lawsuit from Alphabet's self-driving car division Waymo, that accuses it of stealing designs for autonomous car technology known as Lidar. Uber has said the claims are false.
