Carney, who is based in London, joined McCann Worldgroup this week and will report to Pablo Walker, the president of McCann Worldgroup Europe.
This is the first time McCann Worldgroup has had a digital chief for Europe. Carney is charged with leading the agency’s digital offering across the continent and will work with global client Nestlé.
Carney joins from the digital agency Somewhat, which he co-founded in 2011 and where he served as managing partner.
He said: "I’m thrilled to be part of the team at McCann Worldgroup, given their extensive range of capabilities, their many highly creative European offices and their current momentum.
"Helping to expand their existing digital capabilities at this time is an exciting opportunity."
Before founding Somewhat, Carney launched Marvellous, a mobile marketing agency, which was acquired by Aegis Group (now Dentsu Aegis Network) in 2007.
