rachel racusenObama White House communications hand Rachel Racusen is returning to the private sector as director of communications for Snapchat.

Racusen, former VP of communications for MSNBC in a seven-month stint there, returned to the White House last year after a first-term stint directing public affairs for the Federal Emergency Management Agency.

She worked in the agency realm at Dittus Communications and SKDKnickerbocker.

Racusen signs on to Snapchat in New York on Sept. 19.

Snapchat communications chief Jill Hazelbaker departed in October for Uber. Burson-Marsteller alum Mary Ritti is VP of communications out of the company’s base in Venice, Calif.

The social media app has grown widely in the past two or three years from a salacious photo-sharing phenomenon to an established media platform for brands.

The Washington Post, which first reported Racusen’s move, said she will lead development of communications strategies for global content and crisis communications, among other responsibilities.
