Nasdaq OMX GroupI:IXIC said it has re-hired Adena Friedman to be the company's president of global corporate and information technology solutions.

Friedman originally began her career at Nasdaq. She returns to the company after leaving in 2011 to serve as chief financial officer at private-equity firm Carlyle Group. Friedman will report to CEO Robert Greifeld, and is his likely successor when his contract expires in 2017, according to a report by The Wall Street Journal. Greifeld has come under fire for a series of incidents at the Nasdaq, including the problematic Facebook (FB) - Get Facebook, Inc. Class A Report IPO in 2012 and the software glitch that halted trading for several hours last August.

Friedman's hiring is part of an executive restructuring and will correspond with the promotion of Hans-Ole Jochumsen to president of global trading and market services.  Friedman will begin her new role at the exchange on June 12.
