You will be fully responsible for building a stable, structured, high-ROI traffic operation — defining the strategy, managing the budget, leading the team, and driving consistent, predictable performance across all paid channels. The core challenge is not just scaling spend — it is diversifying a concentrated channel mix and profitably scaling new channels and geos to reduce platform dependence. This is a high-impact role suited for someone who thinks in systems, not campaigns. Performance instability, inconsistent execution, and unresolved issues are not acceptable. You are expected to operate with structure and rigour at all times, while acting as the key bridge between product, creative, and analytics.
