• Partner with media buyers to align testing priorities with performance goals and spend distribution.
• Identify creative fatigue early and proactively recommend fresh angles or formats.
• Cross-Functional & Client Leadership
• Act as a strategic partner to clients—leading discussions around creative performance and ensuring our work drives tangible business growth.
• Confidently lead client calls, creative reviews, and performance debriefs—communicating complex data in a clear, compelling way.
• Collaborate with multiple internal stakeholders—including Paid Media Managers, Creative Leads, Designers, and Account Managers—to align creative output with broader campaign and client objectives.
• Balance creative ambition with resource constraints—problem-solving with a solutions-first mindset when faced with production or bandwidth challenges.
• Creative Production Oversight
• Guide and oversee creative execution from concept through to delivery—working across UGC creators, editors, and designers.
• Review and QA creative assets to ensure they meet performance goals, adhere to brand standards, and are platform-optimized.
