About the Opportunity
eBay is a global commerce leader that connects millions of buyers and sellers around the world. We are looking for an intellectually curious, business-savvy, and analytical leader with a deep understanding of marketing effectiveness to join us as the Senior Manager, Marketing Effectiveness.
In this high-impact role, you will be the definitive voice on "what worked and why." You will move beyond simple metrics to deliver deep, causal insights into how our marketing spend drives brand equity and business growth.
Based in Berlin and reporting to the Head of Marketing Effectiveness, you will redefine how eBay measures marketing effectiveness in a privacy-first, AI-driven ecosystem and help lead the transition from retrospective reporting to predictive and prescriptive decision systems for our largest global markets.
About the Team
The Market Insights team is the strategic engine for eBay’s global leadership. We don't just report data; we transform consumer signals into actionable roadmaps. Our team is a collaborative group of researchers and analysts who believe that rigorous measurement is the foundation of great marketing. We operate in a fast-paced, global matrix, partnering closely with Media, Finance, and Brand teams to ensure every campaign contributes to a cohesive global narrative and a healthy marketplace.
Responsibilities
Lead the end-to-end measurement and analysis for all major global campaigns, providing a definitive assessment of performance against brand KPIs and business goals across our global markets.
Partner with the team to contribute to the global brand and reputation tracking program, integrating findings from paid, earned, and owned channels to provide a holistic view of eBay’s market position and sentiment.
Embed measurement into campaign planning and optimization, not just post-launch evaluation
Partner with Data Science, Media, and Finance teams to support broader learnings from Marketing Mix Modeling (MMM) and Multi-Touch Attribution (MTA), ensuring post-launch insights inform future budget allocations.
Establish and maintain a unified KPI hierarchy and measurement "playbook" that ensures consistent reporting and accountability across regional marketing teams.
Reimagine insight generation using AI to move from analyst-driven workflows to scalable, always-on intelligence systems
Synthesize complex performance data into compelling, executive-ready narratives that go beyond "what happened" to explain the "so what" and "what’s next" for senior leadership.
Lead the development of automated, self-service reporting tools (e.g., Tableau, Looker) to provide stakeholders with real-time visibility into campaign effectiveness and brand health.
Act as the primary lead for external measurement partners and research agencies, ensuring they deliver high-quality, actionable insights that meet eBay’s rigorous analytical standards.
Qualifications & Experience
7+ years of experience in Marketing Effectiveness, Brand Insights, or Marketing Analytics, with a heavy emphasis on post-launch measurement and brand health tracking.
Deep proficiency in marketing measurement methodologies, including incrementality testing, causal inference, and interpreting Econometric/MMM outputs
Exceptional communication skills with a "consultative" approach, capable of influencing VP-level stakeholders and driving consensus in a matrixed global environment.
Proven track record of managing campaign measurement across diverse international markets and challenging established methodologies and driving adoption of new ones
A master at "connecting the dots" between brand sentiment data and hard commercial outcomes to build persuasive business cases.
Bachelor’s or Master’s degree in a quantitative or business field (Economics, Statistics, Marketing Science, or similar).
A resilient "can-do" attitude with the ability to navigate ambiguity and manage high-pressure delivery timelines without sacrificing attention to detail.
