Director, Client Service

We are seeking a highly motivated Director of Marketing Science to support our Media Team’s analytics and measurement function. In this role, you will partner closely with senior leadership to bring cross-channel media measurement strategy to life through execution, account leadership, and actionable insights. You will help design and deliver cross-channel measurement solutions -encompassing digital, social, search, linear TV, streaming, and more - leveraging methodologies such as multi-touch attribution, test-and-learn experimentation, and media effectiveness measurement. You will play a critical role in translating advanced analytics into clear recommendations that influence media investment decisions and improve campaign performance.

• Lead the execution of cross-channel media measurement plans, ensuring alignment with broader strategy and business objectives
• Translate measurement frameworks into practical, client-ready outputs (analyses, dashboards, presentations)
• Support campaign and always-on programs with ongoing performance analysis and optimization recommendations

• Support the application of multi-touch attribution methodologies to quantify channel contribution and inform media investment decisions
• Partner with Analytics stakeholders to ensure outputs are effectively integrated into planning and optimization workflows
• Maintain a strong working understanding of Marketing Mix Modeling (MMM) methodologies, including how LIFT/LIFT+ solutions complement MMM and broader ROI measurement tools, and help inform opportunities for future integration or enhancement

• Design and execute test-and-learn initiatives, including A/B tests, lift studies, and incrementality analyses
• Ensure strong experimental design and interpretation of results to provide clear, actionable recommendations

• Translate complex analytical outputs into clear, concise insights and recommendations for internal and client stakeholders
• Develop presentations and materials that connect measurement outcomes to business impact and media and creative optimization opportunities

• Work closely with media strategy, activation, analytics, and client teams to ensure measurement is embedded in planning and decision-making
• Act as a day-to-day marketing science lead on key accounts, ensuring deliverables are timely, accurate, and impactful

• Provide informal mentorship and coaching to junior team members as a subject matter resource
• Contribute to building team capabilities through knowledge sharing and best practice development
• Take direction from senior leadership and proactively identify opportunities to improve execution, workflows, and outputs

• 8–12 years of experience in marketing science, marketing analytics, or media measurement (agency or brand-side)
• Strong working knowledge of cross-channel media measurement, including attribution, experimentation, and ROI analysis
• Familiarity with Marketing Mix Modeling concepts and how different measurement approaches complement one another
• Experience supporting data-driven media planning and optimization across digital and/or traditional channels
• Strong analytical skills, including experience with quantitative analysis and data interpretation
• Ability to translate data into clear, actionable insights for business and client stakeholders
• Collaborative, team-oriented mindset with the ability to influence without direct authority
• Bachelor's degree in a relevant field (e.g., Statistics, Economics, Marketing, Business); advanced degree a plus

Success in this role means consistently delivering high-quality, reliable measurement outputs that drive confident media decisions, while seamlessly bridging strategy and execution to ensure frameworks are not just designed, but fully operationalized. It involves building strong trust with cross-functional partners through clear communication, accountability, and follow-through, and contributing to a scalable, consistent approach to marketing science delivery that elevates both impact and efficiency across the organization.
