The Impact You'll Be Contributing to Moloco:

Moloco Commerce Media (MCM) enables marketplaces to leverage recent advances in AI to deliver highly relevant ads powered by first‑party data.

In this role, you will accelerate MCM’s expansion by acting as a strategic technical partner to cross-functional stakeholders —directly leading the onboarding and optimisation of new marketplace platforms. You will evaluate the performance of MCM platforms across our ad-tech stack (ranking, retrieval, and bidding), identifying actionable technical insights and opportunities that translate into measurable partner impact. By architecting the solutions that enable leading commerce platforms to scale, you will serve as the critical link that transforms European market potential into long-term marketplace success.

Define and Evolve Success Frameworks: Design and refine the metric systems that quantify MCM’s value. You will lead the internal and external alignment on performance drivers, trade-offs, and the "North Star" metrics that govern our ads system.
Influence MCM’s Product and Engineering Roadmap: Proactively define feature priorities by conducting deep-dive analyses that uncover high-impact growth opportunities. Partner with leadership to translate these insights into a technical vision that guides the development of the MCM platform.
Present Complex Insights to Executive Audiences: Simplify intricate data science concepts for non-technical stakeholders and drive the technical narrative in Quarterly Business Reviews (QBRs). Build trust with customer leadership through clear, data-driven storytelling and strategic frameworks.
Orchestrate High-Impact Platform Launches: Lead cross-functional efforts with Sales and Customer Engineering to ensure seamless marketplace launches. Help onboard, support, and scale new marketplace platforms onto MCM and deliver the post-launch exec
