Define winners strictly (≥100 conversions in a single day at target CPA) and kill underperforming concepts quickly.
Initiate aggressive scaling of validated concepts through creative, CTA, visual, actor/avatar, and environment variations.
Launch parallel localization across priority languages (DE, FR, ES, IT) and emerging markets.
Maintain CPA discipline during scale, including blended CPA across cold traffic and retargeting.
Build and manage retargeting campaigns contributing 10%+ of total conversion volume.
Execute and optimize campaigns across Meta, Google Display and Performance Max, Google and Bing retargeting, and emerging channels (TikTok, Reddit, X, AppLovin).
Maintain strict asset naming conventions and campaign organization.
Own creative and performance analytics, including daily reviews, centralized tracking, and rolling performance reports.
Track CPA, CVR, ARPU, and LTV projections to ensure healthy unit economics.
Build and maintain automation workflows for creative performance tracking with 12-hour update cycles.
Translate performance insights into actionable creative direction for producers.
Collaborate daily with UX researchers and data teams to identify new persona and avatar opportunities.
Provide direct, detailed feedback to creative teams and ensure concepts target real, high-intent adult use cases.

Proven track record scaling Meta and Google campaigns profitably to $5M+ per month.
Direct experience managing high-volume creative testing pipelines (50+ concepts per month).
Strong experience with subscription or SaaS products; consumer AI products are a strong plus.
Experience managing multiple brands or campaigns simultaneously, ideally in an agency or multi-product environment.
Expert-level proficiency with Meta Ads Manager, Google Ads, and analytics platforms.
Strong understanding of the Andromeda algorithm, where creative signals outweigh targeting controls.
