Optus Business has replaced its vacant managing director role with former Pricewaterhouse Coopers executive Chris Mitchell.
Mitchell previously spent seven years at PWC, most recently acting as global chief operating officer for the consultancy’s competency centres in Sydney.
He previously held roles as technology consulting and alliance practice leader for Australia, New Zealand and South East Asia, and also as Australia's national leader in technology consulting.
In his new role, Mitchell will be responsible for leading Optus Business' sales, product development and management, service delivery and operations, plus customer experience. He will also be in the Optus senior leadership team led by CEO Allen Lew.
His appointment follows the departure of John Paitaridis in March, who moved on to join BGH Capital after seven years with the company.
During his time at Optus Business, Paitaridis was described as being "instrumental" in winning multi-year strategic partnerships with customers including ANZ, Westpac, Suncorp and IAG.
Paitaridis also secured contracts with Federal Government agencies including the Australian Taxation Office, Home Affairs and the Department of Agriculture and major deals in property, retail and more recently a deal with supermarket giant Coles.
Singtel-owned Optus Business now claims to have 3,000 customers and be underpinned more than 10,000 IT staff.
