About the Role
We’re looking for a paid social expert to own the strategy and execution behind our in-platform performance.

You’ll lead day-to-day execution and continuous optimization to drive performance at scale.
Key Focus Areas

• Own paid social budgets and performance across Meta, TikTok, Pinterest, and other growth channels. Forecast spend, manage pacing, refine full-funnel campaign structures, maintain audience and exclusion lists, and optimize daily to hit CAC and ROAS targets.
