Facebook’s Public Policy Communication Manager Andrew Noyes is leaving to pursue a role with private car service Uber. After four years, he says that he’ll begin work next month managing communications for the startup, one that’s plagued by “complex policy challenges not only in the US, but around the world”.

Hired back in 2009 to help manage public policy communications right from Washington, DC, Noyes has been on both sides of the fence, once as a journalist and now on the company side. He previously blogged for National Journal’s Congress Daily and other Technology Daily, and other publications. He even founded and authored Tech Daily Dose, one of the most popular blogs under the National Journal brand — it has since shut down.

At the time, Facebook’s Director of Corporate Communications and Public Policy Barry Schnitt said that the company needed to “expand its capability to explain to policymakers, the press, and the public how we enable people to share in a more trusted environment, help make the world more connected, and drive economic growth.”

Noyes was responsible for helping Facebook DC promote the social network company’s agenda on enhancing cybersecurity, online safety, digital privacy protection through user control of data, and free speech.

Joining up to Uber surely will be a challenge for Noyes as the startup is definitely facing regulatory challenges from many states in which it operates. California and New York City have begun taking steps to look at their existing laws to see how it can be adjusted to accommodate ride-sharing services like Uber, Lyft, SideCar, and InstantCab. It will certainly be a challenge for Noyes as he’ll have his hands full helping to accomplish the company’s agenda.
