Senior Media Planner, Strategy & Insights

About the Role

The Growth team owns how Polymarket acquires users and converts attention into volume. We move fast, spend real money across a range of channels and geographies, and hold ourselves to business outcomes — not vanity metrics. The media investment function sits at the center of that, and right now it needs someone who can build the analytical backbone that makes every dollar accountable.

This is not a coordination role. You will own the media plan, the forecast, the measurement approach, and the reconciliation. Polymarket operates in an event-driven, highly seasonal environment where timing and pricing can matter as much as budget size — we're looking for someone genuinely restless about finding edge, willing to go looking for the insight nobody asked for and kill their own conclusion when the data doesn't hold.

What You'll Do

• Build the media plan across channels, categories, and geographies, and present a clear, defensible recommendation with tradeoffs and a point of view — not a menu of options

• Own the forecasting layer covering spend, volume, acquisition cost, payback, and seasonality, and maintain scenario models that make tradeoffs legible before capital is committed; when we miss a forecast, explain why and make the next model better

• Pace spend daily and weekly against approved allocations, flag over and under delivery early enough to act, and surface when the actual channel or geographic mix has drifted from the approved plan
