One of Ameritrade Holding Corp.s co-chief information officers is leaving the online brokerage to pursue an IT leadership post at another company, Ameritrade announced on Thursday.
Mok Choe announced his resignation after serving for almost five months as co-CIO along with Raymond Dury. The two had been promoted to the shared post in June after former CIO Jim Ditmore resigned and accepted a position a month later as chief technology officer for infrastructure and operations at Chicago-based Bank One Corp.
Dury will continue as co-CIO—for now. Company officials havent decided whether to continue with a shared CIO post, said Ameritrade spokeswoman Natalie Carlson, in Omaha, Neb. Ameritrade decided to try the co-CIO arrangement as part of an overall company reorganization in June that also included centralizing IT into one technology group.
“It was the right route to take because Raymond has talents and Mok did as well,” Carlson said. “We were just combining them together.”
Carlson couldnt offer details about Choes new position, except to say that the other company will be announcing his hiring in the “near future.” Choes final date at Ameritrade has yet to be set.
Choe joined Ameritrade in 1999 as vice president of the companys application development group. He played an instrumental role along with Ditmore and others in developing Ameritrades in-house online trading system.
