Role Overview

RZR is hiring its first Agency Lead in EMEA, based in London. This is a senior individual contributor role on RZR’s Agency Partnerships team, reporting directly to the Global Head of Agencies. The role is built for a hunter-minded business development professional with deep fluency in the UK and broader European media agency ecosystem. You understand how holding companies operate across EMEA markets, how agencies buy mobile media, and how to build lasting commercial relationships across multiple levels of agency hierarchy. London’s position as the hub of EMEA agency operations makes this role central to RZR’s international growth strategy.

You will own a defined book of business covering holding company and independent agency relationships across the UK and key European markets, driving net new partnerships while deepening commercial engagement within existing ones. The scope spans the full agency landscape: from holding company networks like WPP, Publicis, IPG, Omnicom, Dentsu, and Havas, to high-growth independent agencies across the region. You will serve as RZR’s primary agency presence and voice across EMEA, and you will build that presence from the ground up.
