Jeff Gordon has resigned as the chief executive of Syniverse, the mobile connectivity specialist announced on Tuesday without providing a reason for the move.
The company will begin the search for a replacement immediately, it said. In the meantime, Stephen Gray, a member of the board of directors, will serve as interim president and CEO.
In a statement, Gordon characterised his stint at Syniverse as a positive experience, but did not elaborate on his decision to step down.
"My time at Syniverse has been very exciting as we have transformed the business, completed key acquisitions and expanded our customer base," Gordon said.
Gordon joined Syniverse in early 2008 as chief technology officer, having previously worked for telecoms and technology companies including Convergys, Bell Atlantic and IBM. He later took on the role of chief operating officer and in mid-2011 was named president and CEO.
"Jeff's strategic vision for the business has been integral in driving Syniverse to this pivotal point in its history, and we appreciate his contributions and dedication during his almost seven-year tenure at the company," said Syniverse chairman James Attwood, who went on to also thank Gray for stepping into the interim CEO role.
Gray joined the Syniverse board following its acquisition by the Carlyle Group in January 2011. He has 25 years' experience in the telecoms sector and also serves on the board at CommScope and various other companies.
"As a leader in the enablement of LTE technology with reach to more than 6 billion mobile devices, Syniverse is an exceptional company poised for continued growth in the mobile ecosystem," Gray said.
