The appointment follows Molson Coors taking a majority stake in the brand, which had fallen into administration earlier this year. BMB already works with Cobra's sister brand Carling.
The brewer has created a dedicated business unit, the Cobra Beer Partnership, to grow the beer, which will be supported by a £10m marketing spend over the next three years.
Under Cobra's previous management, which included Will Ghali as marketing director, Cobra attempted to move away from its Indian-restaurant heritage into mainstream pubs and bars. However it has since returned to its ethnic food heartland and is sponsoring National Curry Week from 22-28 November.
Kevin Wallace, director of marketing for Cobra, made the appointment.
