• An individual who thrives in a fast‐paced, high‐pressure media publisher environment, juggling multiple priorities and working with all sorts of internal & external stakeholders.
• Experience with display, video pre‐roll, and rich media units is a must – you should also be able to dig into code to spot irregularities like Cachebusters.

What You Will Do

• Help the sales team before the sale, and take charge of forecasting inventory and media planning.
• Help legal & sales during the IO process by double checking and making sure the IO matches the media plans.
• Work with the account manager/director to request the right creative assets, test them thoroughly & own fixing any issues with stakeholders.
• Manage and deliver ad campaigns sold directly by our sales team.
• Keep an eye on campaigns every day with thorough health checks, give proactive reports on status updates & recommend improvements where needed to boost campaign performance.
• Give campaign reporting and insights to the sales team.
• Help finance with their monthly reconciliation.

• Knowledge of Google Ad Manager 360.
• Experience with media planning and a strong understanding of the RFP process, including assessing inventory availability and pricing strategies for direct‐sold and programmatic deals.
• Well‐versed in DMP platforms like Audigent, Permutive, ArcSpan, or LiveRamp, and know how to build, activate, and optimize audience segments.
• Experience trafficking and troubleshooting rich media creatives using Celtra, Clipcentric, or other vendors.
• Highly organized and skilled in project management, with experience using tools like Asana, Monday.com, or Trello to coordinate tasks across teams.
• A strong analytical and critical thinker who can easily spot patterns within large amounts of data and translate insights into actionable recommendations.
