The WPP-owned media agency said it has created the role to meet the demand from clients for help in developing digital business and marketing strategies.
Jason Dormieux, a joint chief executive of MEC, said: "His track record of working with clients across the Asia-Pacific region to develop their digital transformation strategies is outstanding and we’re delighted he’s joining our senior leadership team in the UK.''
Poole, who will join the management board of MEC in the UK, was previously at MEC Asia-Pacific where he spent six years leading the agency's digital transformation across the region. He worked with clients such as Colgate-Palmolive, Mercedes-Benz, Singapore Airlines, SingTel, Chevron, Citibank, Sony, Chanel, Marriott and Tiffany & Co.
Poole said: "MEC UK is considered one of the best agencies anywhere in the world, with exceptional people that I can't wait to work with.
"MEC is all about growing clients' business through doing great work in an increasingly digital world. That is my starting point for this role, and I'm just looking forward to getting stuck in."
