SAIC Headquarters in McLean, Va. (Jeffrey MacMillan/JEFFREY MACMILLAN)

Tony Moraco, who heads SAIC’s Intelligence, Surveillance and Reconnaissance group, will head the smaller company.

SAIC announced in August that it would separate into two pieces by the end of next year. An estimated $7 billion-a-year IT company — which SAIC calls its “solutions” business — will focus on technology for the national security, engineering and health sectors.. A roughly $4 billion-a-year services business is to specialize in areas like systems engineering and technical assistance, financial analysis and program office support.

SAIC has a 50-employee program office working on the details of the split, such as what the companies will be called and where they will be headquartered. The leadership structure announced Monday is part of that process..

In the solutions business, Jumper’s team will also include Stu Shea, SAIC’s chief operating officer; Mark Sopp, its chief financial officer; and Vince Maffeo, SAIC’s general counsel. The company will start a search for a national security sector president, given that Moraco will be leading the separate business, SAIC said in its announcement.

At the services business, Moraco is joined by Edward “Sandy” Sanderson, a member of SAIC’s board of directors, who will be non-executive chairman of the new company’s board, and Tom Baybrook, now acting president of SAIC’s defense solutions group, who will be chief of administration and operations at the new company.

John Hartley, corporate controller at SAIC, will become chief financial officer of the services business, and Deborah Lee James, now executive vice president for communications and government affairs, will lead the company’s technical services sector.
