In this role, you will ensure all media deliverables are accurate, timely, and comprehensive—moving beyond just the “what” to understand and communicate the “why.” As a multi-tasking professional, you will execute core media operations with increasing independence, spot emerging trends and patterns across campaign data, and actively partner with cross-functional disciplines to help craft solutions and recommended next steps. Key Responsibilities: ​ ​Tactical Planning & Operational Excellence End-to-End Media Execution: Drive day-to-end planning tasks, including audience research, media plan matrix management, creative spec collation, trafficking coordination, and financial reconciliation. Tool & Process Proficiency: Utilize core agency and planning platforms (e.g., GWI, Olive, PFC, ad servers) with speed and precision. Quality Assurance (QA): Ensure operational accuracy across campaign setups, tracking tags, media briefs, and billing milestones before deliverables go out. Time & Priority Management: Manage your own daily schedule effectively, prioritizing tasks to consistently meet and exceed deadlines across concurrent campaigns. Cross-Functional Collaboration & Communication Internal Team Partnership: Foster strong collaborative relationships with key discipline counterparts—including Client Services (CS), Activation, Analytics, and Ad Operations. Cross-Discipline Alignment: Proactively initiate conversations across internal teams to troubleshoot issues, gather required inputs, and ensure seamless handoffs. Lateral Management: Work laterally within the pod/discipline team to ensure alignment on campaign milestones and shared project timelines. Meeting Support & Accountable Follow-Through Meeting Contribution: Actively participate in internal campaign, tactical, and status meetings. Action Item Ownership: Partner with Planning Managers to accurately capture meeting notes, open questions, and agreed next steps. Resolution Driver: Take accountability for following up on assigned media actions and liaising with stakeholders to obtain timely answers. Reporting, Data QA & Emerging Insights Reporting Pull & Verification: Own the compilation and rigorous data QA of regular reporting deliverables (e.g., weekly pacing/performance, DCA inputs). Pattern Recognition: Answer tactical, campaign-level questions (e.g., data source timing, pacing variances) and begin identifying noteworthy trends in performance data. Solution-Oriented Thinking: Help outline initial observations and potential solutions for campaign hurdles alongside your Planning Manager. Continuous Learning & Self-Growth Category & Discipline Fluency: Deepen your understanding of client Product Areas (PAs), historical campaign performance, competitive context, and audience dynamics.
