About the role
As Regional Client Partner, you will be the face of the agency in your territory. Over time, you will own the relationship, commercial growth, and strategic direction for existing major clients, under the initial direction and guidance of the relevant Group Client Partner — while also driving new business. The balance between existing client growth and new business will flex. Initially, you will be assigned one or two existing pieces of business to ensure you still have capacity to handle new business conversion. Supported by our London-based specialists (search, content, strategy, etc.), you will lead or spearhead initial, in-person engagements, and serve as the primary trusted advisor.

Cross-Functional Leadership & Delivery
