• Coordinate Remote Support: Brief remote colleagues, set priorities and deadlines, check their work and retain accountability for delivery.
• Manage Media Stakeholders: Own day‑to‑day media communication across clients and internal teams, responding to media queries, providing clear recommendations and ensuring requests are progressed within agreed timelines.
• Lead Testing & Creative Performance: Work with creative and account teams to test audiences, messaging, formats and landing pages. Analyse creative performance and provide clear insights and recommendations to inform future creative briefs, iterations and testing priorities.
• Resolve Campaign Issues: Diagnose delivery, tracking and performance problems, taking action and escalating where needed.
• Maintain Media Standards: Keep account structures, conversion tracking, quality checks, reporting and core media documentation accurate and consistent. Ensure media actions, recommendations and approvals are clearly tracked through to implementation.

The principles you'll live by…

• Raise issues early and bring practical recommendations.
• Communicate clearly with clients, colleagues and remote support.
• Take ownership of campaign delivery and check the detail.
• Use testing and feedback to improve campaign performance.

• Experience or strong working knowledge of the broader paid media ecosystem, such as programmatic display/video, BVOD/CTV, digital audio and other performance or awareness channels.
• The ability to manage multiple clients, markets and concurrent media priorities independently, with strong attention to follow‑through and deadlines.
• Confidence leading client media discussions, presenting strategies and explaining performance, recommendations and trade‑offs.
• Strong commercial judgement, including forecasting, scenario planning, target feasibility, budget allocation and spend control.
• Experience briefing remote support and reviewing work against clear standards.
