Bain's immediate remit will be to lead planning on the agency's Toyota Europe account during the next six months. However, this will evolve into a roving brief, which will allow Bain to troubleshoot on various accounts throughout the network.
Bain quit FCB last November after 14 months in the role, at a time when the agency had just lost its Weetabix and Waitrose accounts. He had been hired by the FCB London chairman, John Banks, as part of a "dream team" that also included the creative director, Al Young, and the managing director, Jonathan Rigby. Rigby departed from the agency last month.
Before working at FCB, Bain spent three years at Fallon New York as the head of planning, where he was responsible for the Timberland global business and the North American Starbucks, PepsiCo and Time Warner accounts.
Kevin Dundas, Saatchis' global head of strategy, said: "I am committed to building a global strategic team that draws on senior resource from around the world. As the strategic network is brought closer together as one team, I am able to deploy senior talent to bolster the local talent wherever the opportunity exists. This is all part of the plan to make our creative output stronger."
The Toyota account is Saatchis' second-most lucrative account, behind Procter & Gamble. However, the agency's hold on the global business has been threatened in recent years. In 2003, the San Francisco agency Attik won the brief to launch the Toyota Scion in the US, while last year, Clemmow Hornby Inge picked up a European Toyota brief.
