The Role

This role is for a Client Partner who can turn trusted strategic client relationships into measurable and sustainable growth. Working closely with the Chief Client Officer, the Client Partner will own growth across a focused portfolio of strategic clients, identify and shape demand early, develop qualified pipeline and mobilise the best of Merkle and dentsu around client outcomes.

This is not an account management role, a delivery leadership role, or a role for someone whose primary focus is internal operations. We are looking for someone who is relentlessly client focused, commercially driven and energised by growth; someone who creates opportunities rather than only responding to them, looks outward to markets and client needs, builds influential relationships, and makes growth a natural outcome of trust.

The purpose of the role is to accelerate sustainable growth by building senior relationships, identifying new opportunities, shaping solutions and creating significant commercial value for both clients and the business.

The Client Partner will work with the CCO and partners in Solutions and Delivery to shape growth strategies, support major client relationships and develop emerging talent within the client leadership team.

Your success will be measured by your contribution to portfolio growth through relationship depth, opportunity identification, deal closure, and your ability to identify and develop high-potential team members.
