HSBC in McLean, Va., has hired a longtime Citigroup executive, William Brown, to lead its U.S. branch network.

Brown's mission in the newly created job is to expand the market share of HSBC's 248 branches in the United States, according to a press release Monday. He will be based in New York City.

Brown joins HSBC after a 17-year stint at Citi, where he worked in numerous positions including serving as market president for New York City. He began his career in the Navy and served on the Navy staff at the Pentagon.

Brown's "unique blend of proven leadership skills and retail banking experience will be invaluable as we build our business in the U.S.," Kevin Martin, head of retail and wealth management for North America, said in the release.
