Ahead of the finalization of its joint venture with Sprint Nextel's Xohm unit, Clearwire Corp. provided details about its top management, and said its chief financial officer was leaving the company.

In an SEC filing, Ben Wolff, Clearwire's CEO, said that Barry West would be the company's president and chief architect, and that Atish Gude would serve as the chief marketing officer of the mobile WiMAX company. In the filing, Wolff also said that CFO Jon Butler would be stepping down to "spend more time with his family."

Both West and Gude will relocate to Clearwire's offices in Seattle.

Clearwire announced in May that it was merging with Sprint's Xohm unit to create a new company, and the joint venture has received billions of dollars in capital investment from Google, Comcast, Intel and other Internet and technology power players. Wolff said he expects to have all staff positions finalized by Oct. 31.
