Responsibilities

  • Own strategy, execution, pacing, and optimization across paid social channels.
  • Serve as in-house expert on performance social, with deep expertise in Meta's advertising ecosystem and strong understanding of unlocking incremental scale on TikTok.
  • Develop and execute a testing roadmap across audience strategy, bidding, campaign structure, creative, and measurement to continuously improve efficiency and identify new growth opportunities.
  • Partner closely with TikTok and Meta account teams to influence product roadmaps, gain early access to beta features, and ensure leveraging platform capabilities to the fullest.
  • Translate MMP and backend performance data into clear insights, budget recommendations, and executive-ready reporting.
  • Work closely with Analytics and Data Science to validate attribution, forecast accurately, and optimize toward KPIs.
  • Partner with Creative to develop channel-specific creative strategies, establish a rapid feedback loop, and continuously improve performance through testing and iteration.

  • Experience partnering closely with Creative teams to inform creative strategy and establish high-velocity testing programs.
  • Demonstrated success designing and owning a structured experimentation roadmap across channels, creative, audiences, and platform capabilities.
  • Experience in gaming, fintech, sports betting, or another high-growth consumer app environment.
  • Comfortable managing and developing team members while maintaining a high bar for execution.

Nice-to-Haves

  • Built or significantly scaled TikTok into a major acquisition channel from an early stage.
  • Experience implementing AI-driven workflows or automation to improve UA efficiency and creative testing.
