Leading a team of effectiveness specialists, this role establishes a unified measurement framework that connects brand, media, digital, and customer insight. The role partners closely with senior stakeholders across Marketing, Digital, Finance, and Insight functions to ensure marketing investment decisions are grounded in robust, forward-looking, and holistic effectiveness principles.
