Online deals company LivingSocial is cutting 400 jobs worldwide, or about 9 percent of its work force, as the deals market continues to face challenges.

LivingSocial spokesman Andrew Weinstein said Thursday that all but a few dozen of the cuts are in the United States. The company’s sales force faced the highest number of cuts, while others are in customer service and editorial, the people paid to write up the deals. LivingSocial said it is moving its customer service operations to Tucson, Ariz., from Washington, where it has its headquarters.
