London | Hybrid (3 days p/w) | Salary to £90,000 + benefits

A leading media agency is hiring a senior Marketing Science leader to help shape the future of analytics, effectiveness and measurement across some of the most recognised consumer brands in the market.

This is a genuinely high-impact role sitting at the intersection of MMM, advanced analytics, experimentation and client leadership. You’ll lead a team of 8, partner closely with senior agency leadership, and act as a trusted advisor to major clients across retail, entertainment, charity and financial services sectors.

Why this role stands out:

• Lead large-scale MMM, geo-testing, brand lift and effectiveness projects across flagship clients
• Highly visible leadership role helping drive the agency’s wider analytics and effectiveness proposition
• Strategic and commercial remit – not just delivery, but shaping client direction and growth opportunities
• Manage and develop a high-performing team of AD’s and Managers within an established Marketing Science function
• Work with senior stakeholders internally and externally, influencing business and media investment decisions

What they’re looking for:

• Strong media agency or media-led consultancy background within MMM, effectiveness or marketing science
• Deep understanding of measurement frameworks, econometrics, experimentation and advanced analytics
• Proven experience leading client relationships and translating analytical outputs into commercial recommendations
• Strong people leadership and stakeholder management skills
• Ability to operate strategically while still being credible in the detail of complex analytics projects

This is not a pure data science role. They need someone commercially sharp who understands how effectiveness, measurement and media performance connect to real business outcomes.
