Until February 2012 he led the Leeds office of BAM Construction, having spent 32 years at the firm. Since then he has been commercial director of Hull-based contractor C Spencer.
His target is to help grow Miller Construction’s turnover to £600m by 2015. It was £239m last year.
Chief executive Chris Webster said: “We are delighted that Charlie is joining our senior management team. Charlie is a well-respected industry figure, who knows how to deliver successful projects for clients.
“Scotland is an important region for our business and I have every confidence that Charlie will be instrumental in delivering our services as we progress with our strategy of providing ‘end-to-end’ services for our clients across the UK.”
Mr Dunn said: “Miller has a strong reputation for quality and progressive thinking and I am delighted to be taking this role to head up Scottish operations.
“Over the last 12 months, there have been a number of high profile appointments to the senior management team and I very much look forward to playing my role in Miller’s growth story.”
The move to Miller will also see Mr Dunn return home to his native Scotland after 20 years in northern England. He begins his new job on 5th November 2012.
