The current managing director and vice-chairman of Riverside, Colin Black, will step aside on Boyers' arrival. Riverside artistic director William Burdett-Coutts said: "Colin had retired and I effectively forced him to take the job on but we're both delighted to have Jim on board."
Boyers will assume managerial duties at the TV studio operations at the end of the month and will be replaced at Editworks by co-founder Graham Hutchings.
Hutchings said: "I will continue to edit as well as manage the company as we continue to expand with a second audio suite and Symphony in the pipeline."
Boyers said of his decision to become managing director of Riverside TV Studios: "Studios are my first love and where most of my experience lies but I have no regrets from my time with Editworks."
Riverside's television studio, which measures 5,625 sq ft, was initially a BBC studio and dates from the 1950s.
In the three years since the Editworks management buyout, Boyers has steered the Charlotte Street facility towards a £2m-plus turnover. It was the second highest rated facility in the UK, according to Broadcast'srecent post-production survey.
