The new senior jobs at MNF are chief executive wholesale and chief executive direct.
"I am pleased to announce the addition of two key roles to the MNF Group executive team," said co-founder and group CEO Rene Sugo.
"The company is experiencing exceptional organic growth across both its direct and wholesale customer bases. These new roles will ensure there is strong focus and commitment directly on the areas of the business that will drive long-term growth.
Jon Cleaver moves into the role of chief executive wholesale from his previous position as chief commercial officer.
He has been with the group for eight years, including a stint as general manager of sales and business development at MNF subsidiary Symbio Networks.
Cleaver previously worked as a senior account manager at Telstra Wholesale.
"Having been in the wholesale telecoms market for over 15 years, I've witnessed plenty of developments in this area. However, with the current technology disruption, I believe the opportunity for pronounced and genuine change has never been greater," said Cleaver.
"We are uniquely positioned to maximise this growth within Australia and further into Asia Pacific whilst also transforming the global business and unlocking recurring revenue models."
In his new role as chief executive direct, Iain Falshaw is responsible for the group's consumer, SMB and Enterprise businesses.
He joined MNF Group as a result of the acquisition of Telcoinabox, where he was chief commercial officer.
"As the market continues to shift to a mobile-first mindset, and demand for unified communications as a service keeps growing significantly, I'm excited about the growth opportunities this presents across MNF Group's direct segment," Falshaw said.
Falshaw's 30 years of experience in the industry positions at Optus, Cable and Wireless, Dataroam, and ACN Pacific. He has also served as a non-executive director of the TIO,
In addition to his role at MNF, Falshaw is chairman of social enterprise telco Jeenee Mobile and a non-executive director of IntaCept, which brings a digital approach to the testing and tagging of electrical equipment.
He holds an honours degree in business studies from Robert Gordon University (Scotland).
