• Experienced in an agency environment: you know your way around briefs, budgets, and client and partner management.
• Ideally bring B2B or entertainment experience.
• Tenacious, proactive, and solutions oriented, with a strong “can‑do” attitude.
• A hunter, looking for the next brief while working on the current one.
• Skilled in deck writing, communication, and stakeholder management.
