Senior Manager, Retail Media & Marketplace Analytics

What You'll Do: Own end-to-end analytics and performance measurement across retail media and marketplace channels, spanning both paid and organic initiatives. Develop and maintain dashboards and reporting that track key performance indicators, including ROAS, TACOS/ACOS, conversion rate, share of voice, new-to-brand acquisition, and contribution margin. Build SKU- and ASIN-level reporting to connect media investments, organic rankings, content quality, inventory, and profitability. Identify growth opportunities through deep analysis of marketplace trends, customer behavior, and performance data. Design and evaluate test-and-learn initiatives, including incrementality studies, holdout testing, and geo experiments, to optimize media effectiveness and investment strategies. Analyze the impact of product detail page enhancements—including titles, imagery, A+ content, video, and reviews—on search visibility, click-through rates, and conversion. Partner cross-functionally with retail media, marketplace operations, merchandising, and content teams to diagnose performance shifts and recommend strategic actions. Develop guardrail metrics and early-warning indicators to proactively identify risks such as declining conversion, rising TACOS, inventory constraints, or buy box challenges. Deliver assortment and merchandising insights related to demand trends, seasonality, pricing, and category performance to support business planning decisions. Lead the integration and governance of marketplace data sources to ensure data accuracy, consistency, and accessibility across teams. Standardize reporting methodologies and KPI definitions across stakeholders and external partners. Present complex findings in a clear, concise, and executive-ready format that drives decision-making.
