Monica Fan will join Millennium Global as managing director and head of business development on May 16, confirmed Louise Beeson, a spokeswoman.
Ms. Fan will report to Mark Astley, Millennium CEO, and will be based in the London office of the global currency and currency overlay manager.
Ms. Fan's new position is part of an expansion of the firm's marketing program; she will not directly replace anyone, Ms. Beeson said.
Ms. Fan was vice president and senior currency product engineering engineer in State Street Global Advisors' London office; she left in March, said spokeswoman Arlene C. Roberts. Ms. Fan's responsibilities were temporarily assumed by other team members and SSgA is conducting a search to fill the position, Ms. Roberts said.
Millennium Global managed $12 billion as of April 30.
