The plan was viewed internally as an effective demotion for Jones, who was hired previous year as president and second in command, a person familiar with the matter said.
His role was put into question after Uber earlier this month launched a search for a chief operating officer (COO) to help chief executive Travis Kalanick.
The now former Uber president was brought in from Target, where he served as chief marketing officer. In his statement, Jones says that he has realized that his beliefs and approach to leadership clash with what he has seen in Uber in his 6-month stint, perhaps referring to the scandals that the company has been involved in.
Uber President Jeff Jones has left the ride-hailing service after little more than six months in the job.
But clearly Jones doesn't think his way of doing things is going to be respected at Uber, which belligerently enters markets in full knowledge its activities flout local law, sabotages regulators' efforts to police it, stands accused of turning a blind eye to institutional sexism and of stealing Google's autonomous auto plans.
In a post on Medium, another woman engineer at Uber, Aimee Lucido, called Fowler's tale "disgusting and appalling and horrifying", but not surprising since it is something she has been "shouting about" for years.
Uber CEO Kalanick then held a teary all-hands meeting at which he apologized for leading the company he co-founded to a point of such negativity and discord.
In October, Uber hired Jones from his position at Target to help clean up the image problems the company cultivated through some of its questionable business tactics and Kalanick's increasingly frequent missteps.
The New York Times reported that Uber had developed a tool that it used to deliberately deceive authorities in cities that had either banned the app or were trying to restrict its use.
Jones spent much of the beginning of his tenure as the president of ride-sharing driving for Uber and meeting with drivers, after which he sent drivers an email about what he learned and what the company intends to do.
Jones was viewed by many as the "adult in the room" - an executive with experience as a leader at a public company that had undergone a period of intense crisis. Earlier this month, Ed Baker, Uber's vice-president of product and growth, and Charlie Miller, Uber's famed security researcher, departed.
