The Edinburgh-based firm said former senior vice president of Atos and chief executive of Capita Scotland, Steve Langmead, was joining as a non-executive director in an “outward-looking role”.
He will be joined in a similar capacity by John Bennett, director with European equities at Janus Henderson Investors and a non-executive director with Rangers Football Club.
News of the twin appointments comes just days after Commsworld, which was founded in 1994, reported record revenues of more than £15 million for 2017 while forecasting that staff numbers would grow to at least 100 in 2018.
Chief executive Ricky Nicol said: “To land two titans of industry in Steve and John is a coup and we’re thrilled to have their experience to draw on.
“We’re at such an exciting juncture for the business and at a point in time where we are able to plan further into the future than ever before.”
The firm’s work on a seven-year Glasgow City Council contract, announced in early 2018, will see it play a major role in transforming the city into one of the world’s most digitally advanced.
It will deliver a “greatly enhanced” wide area network of ultra-fast pure-fibre connectivity, as well as rolling out an IP telephony system for more than 16,000 council users and a 550-plus seat contact centre.
