Babergh and Mid Suffolk councils this week confirmed Arthur Charvonia as joint chief executive.
Mr Charvonia comes to the role after being strategic director at Suffolk Coastal and Waveney District councils.
Mr Charvonia will officially take up his role in the New Year but will begin attending key meetings between now and then.
He has worked in local government for the last 11 years and been strategic director for eight years serving as joint strategic director for the past six years.
He is a qualified barrister and has also worked for Norfolk Police and the London Borough of Waltham Forest before coming to Suffolk.
He has lived in East Anglia since 2000 and is married with three children and a dog called Charlie.
He said: “I am committed to working with my new colleagues to engage with and listen to local residents to identify their needs and ambitions. We need to deliver impproved services to our communities in innovative and accessible ways.”
