BigBand Networks’ shakeup of its executive team continued late last week when the company announced that Ravi Narula was taking over the position of chief financial officer from current CFO Moe Castonguay.

Castonguay will serve as CFO until May 1. BigBand cited Castonguay’s desire to return to the East Coast as the reason for him leaving the company.

“Moe has demonstrated the highest levels of integrity and competence during his tenure at BigBand and has helped establish a level of transparency, control and planning that will benefit us for years to come,” said Amir Bassan-Eskenazi, president and CEO of BigBand Networks. “His decision to refocus his life back on the East Coast was one that I have to respect and support. I am thankful for his leadership and wish him the best in his future endeavors.”

Narula joined BigBand in 2005 and is currently the vice president of finance and worldwide controller. He has also served in other senior financial roles during his tenure at BigBand, including chief accounting officer. BigBand said he was instrumental in taking the company public and building the financial operations team.

“We are pleased to promote Ravi to his new position as chief financial officer,” Bassan-Eskenazi said. “His financial leadership has been an important component of our strategic and operational performance over the past four years. We look forward to his continued contribution as part of the executive team. Ravi is Moe’s recommended successor, and they will continue their great team work in the coming months to assure a smooth transition.”

Last week, BigBand Networks announced that David Heard had resigned as the company’s chief operating officer and that Sean Rooney resigned as senior vice president of worldwide sales.

BigBand also announced that Mike Pohl was appointed as a non-executive chairman of the board of directors. With Pohl’s appointment as chairman, BigBand separated the roles of chief executive officer and chairman, which were previously held by Bassan-Eskenazi.
