• Maintain clear campaign documentation and follow internal approval, QA and governance processes.
• Contribute to new-business proposals, media recommendations and publication landscape updates.

• Strong written and verbal communication skills, with the confidence to manage day-to-day interactions with media owners and internal stakeholders.
• Excellent attention to detail and a disciplined approach to checking dates, costs, specifications and bookings.
