• Ensure testing programs meet rigorous standards for validity, reliability, and business applicability.

• Conduct advanced statistical analyses to evaluate test performance and marketing effectiveness.
• Lead large-scale measurement initiatives including Marketing Mix Modeling (MMM), incrementality analysis, causal inference studies, and attribution validation.
• Apply statistical methodologies including power analysis, confidence interval estimation, significance testing, and experimental design techniques.
• Identify drivers of marketing performance and provide data-driven recommendations for investment optimization.
• Partner with marketing leadership to quantify the impact of strategic initiatives and media investments.

• Own and manage the marketing testing and measurement database environment.
• Develop, maintain, and optimize SQL-based datasets, test repositories, and reporting structures.
• Ensure data quality, consistency, documentation, and governance across testing programs.
• Collaborate with marketing, engineering, and technology teams to improve measurement capabilities and data accessibility.
• Establish scalable processes for maintaining historical test results and measurement frameworks.

• Develop executive-ready presentations, reports, and dashboards that communicate test results and strategic insights.
• Present findings and recommendations to senior leadership and executive stakeholders.
• Translate complex statistical analyses into actionable business recommendations.
• Establish standardized testing scorecards, readout templates, and measurement frameworks.
• Provide ongoing guidance to stakeholders on experiment interpretation and decision-making.

• Partner with Marketing, Media, Product, Technology, Analytics, and Executive teams to define and prioritize testing roadmaps.
• Serve as a trusted advisor on measurement strategy and marketing effectiveness.
• Foster a culture of experimentation, data-driven decision making, and statistical rigor throughout the organization.
• Potentially manage and mentor junior analysts or measurement specialists as the team evolves.

• Master's degree in Statistics, Mathematics, Data Science, Operations Research, or another highly quantitative field.
• 7+ years of experience in marketing analytics, measurement, experimentation, statistics, or related analytical disciplines.
• Advanced proficiency in SQL, including database management, complex query development, and data validation.
• Experience designing and evaluating controlled experiments and large-scale marketing tests.
• Strong understanding of statistical inference, experimental design, causal measurement methodologies, and hypothesis testing.
• Experience presenting analytical findings to senior leadership and executive stakeholders.
• Exceptional communication, storytelling, and stakeholder management skills.
