Director Brand Management, EMEA in London

Responsible for leading the operationalisation of the client's Measurement & Learning framework. The role translates the client's measurement transformation agenda into practical, scalable ways of working across global, regional, and local teams, ensuring that KPI frameworks, test-and-learn programmes, reporting outputs, modelling solutions, and optimisation routines are embedded into the process and used to improve business outcomes.

This is a hands-on measurement leadership role requiring strong stakeholder orchestration, measurement fluency, and the ability to connect strategy with execution. The Measurement Director will partner with internal and external stakeholders, Publicis capability teams, data science, reporting, commerce, strategy and insights, media, and regional teams. They will align priorities, clarify ownership, and simplify measurement frameworks. They will also accelerate the delivery of measurable learning across Paid, Earned, Shared and Owned media, commerce, growth audiences, campaign reporting, post-campaign analysis, and advanced measurement programmes.

Role Objectives:

• Thought Leadership & Industry Innovation: Partner with the client and Publicis leadership to translate business priorities into actionable measurement plans, learning agendas, KPI definitions, test designs, and reporting requirements.
• Own the measurement roadmap, including milestones, stakeholders, dependencies, risks, and governance required to operationalise measurement.
• Drive alignment across client stakeholders and Publicis teams on ownership of measurement topics, including growth audiences, global test-and-learn, connected commerce measurement, reporting, PCA evolution, and the broader application of advanced measurement approaches.
• Ensure wider integrated efforts across Strategic Planning, Account Management, and Investment teams to ensure a consistent voice and point-of-view is being facilitated to clients, partners, and consumers.
• Champion a practical test-and-learn culture focused on business outcomes, consistency of approach, and the reapplication of learnings across markets, brands, and regions.
• Facilitate workshops and stakeholder sessions to clarify measurement scope, priority use cases, KPI definitions, data inputs, decision rights, and activation requirements.
• As the measurement roadmap matures, partner with Creative, Production, Media, and Strategy teams to identify opportunities to extend measurement into creative effectiveness, using production efficiencies and creative testing to generate sharper learnings on performance and business impact.

Measurement Operationalisation & Delivery:

• Lead the day-to-day operationalisation of measurement for the client, converting strategic frameworks into actionable delivery plans, meeting cadences, stakeholder maps, and clear workstream ownership.
• Coordinate with global, regional, and local teams to ensure early consultation, clear handoffs, and practical adoption of measurement requirements before campaigns, planning cycles, and QBRs.
• Support the evolution of post-campaign analysis from static reporting into a forward-looking optimisation input that connects media, commerce, Strategy and Insights, creative, and business outcome learnings.
• Partner with reporting, data operations, and dashboard teams to ensure measurement outputs are reliable, consistent, interpretable, and aligned to agreed KPI definitions and business questions.
• Create clear narratives for stakeholders when measurement approaches need to change, balancing methodological robustness, available data, timeline constraints, and client expectations.

Marketing Science, Modelling & Learning Agenda:

• Lead the measurement workstream for learning agendas, including PESO test designs, growth audience measurement, connected commerce measurement, campaign effectiveness, and outcome-based optimisation.
• Work with data science and marketing science specialists to identify fit-for-purpose measurement and modelling solutions, including MMM, incrementality, attribution, market testing, outcome modelling, and other approaches that help inform future planning and investment decisions.
• Assess data availability and readiness across markets, including sales, media, commerce, audience, CRM, social, and campaign performance data, and translate constraints into pragmatic measurement recommendations.
• Provide strong technical fluency to guide analysts and data scientists, challenge assumptions, review methodology, and translate outputs from MMM and other measurement models into clear, forward-looking recommendations for non-technical stakeholders.

Stakeholder Management, Governance & Team Leadership:

• Act as a senior day-to-day measurement point of contact for internal and external stakeholders, coordinating across Mars clients, Publicis measurement leadership, capability leads, and regional teams.
• Build and maintain stakeholder maps, governance routines, and milestone trackers so that decisions, dependencies, and ownership are visible and actively managed.
• Manage delivery across multiple concurrent workstreams, ensuring quality, pace, and consistency while balancing urgent stakeholder needs with long-term measurement transformation.
• Present measurement recommendations clearly and diplomatically, turning complex methodological or data limitations into practical client-ready narratives.
• Coach and guide analysts, project managers, and cross-functional partners, helping teams prioritise high-value measurement outputs over reactive firefighting.

Qualifications:

• Minimum of 7–10 years of experience in marketing measurement, media analytics, marketing science, or data-led transformation, ideally within a global agency, CPG, retail, commerce, or client-side marketing organisation.
• Proven experience managing complex, senior stakeholder relationships and delivering measurement programmes across global, regional, and local markets.

Technical Skills:

• Strong practical knowledge of marketing measurement approaches, including KPI frameworks, learning agendas, test-and-learn design, MMM, attribution, incrementality, PCA, reporting, and optimisation.
• Fluency in how MMMs are designed, interpreted, and used in practice, including understanding inputs, assumptions, limitations, response curves, scenario planning, and how model outputs should inform budget allocation, channel strategy, and optimisation decisions.
• Working familiarity with BI and analytics tools such as Power BI, Tableau, Datorama, Excel, SQL, Python, R, or similar platforms; coding expertise is helpful but not required for success in this leadership role.

Soft Skills:

• Excellent problem-solving abilities, with the confidence to impose structure on ambiguous, fast-moving transformation workstreams.
• Strong communication and presentation skills, including the ability to explain technical measurement topics in clear, client-ready language.
• Proven ability to lead through influence across cross-functional teams, including measurement, media, commerce, Strategy and Insights, reporting, data science, project management, and client stakeholders.
• Highly organised, proactive, and collaborative, with the ability to drive clarity, accountability, and adoption across multiple markets and stakeholder groups.
