• Execute campaigns directly where appropriate (YouTube, programmatic placements) and manage relationships with media agencies for TV, premium CTV, and strategic partnerships
• Collaborate closely with cross-functional partners across brand, creative, data and engineering
• Design and run structured experiments to evaluate channel viability and emerging opportunities - setting clear success metrics and synthesizing learnings into actionable recommendations
