Atom Apps is a hyper-growth, AI-powered mobile app company with over 15 million U.S. downloads and a growing global footprint. We specialize in full-cycle app development — from ideation to monetization — across diverse verticals. Our model is agile, data-driven, and laser-focused on scale.

We’re now looking for a Performance Marketing Lead (Paid Social) to drive user acquisition strategy across Meta and TikTok. This is a high-impact, strategic role where you’ll define growth playbooks, own budgets, shape creative direction, and act as a key contributor to product-market expansion initiatives.

This role is ideal for a seasoned growth marketer with a proven track record of managing multi-million dollar paid social budgets for mobile-first products, and who thrives in a performance-obsessed, autonomous environment.

Your Mission

• Own and scale our Paid Social acquisition engine across Meta and TikTok — from strategy and execution to performance and profitability.
• Lead the full funnel: media buying, targeting, creative strategy, user segmentation, and LTV optimization.
• Develop and implement playbooks to continuously optimize CAC, ROAS, and scaling potential across geos and products.
• Partner with Data, Product, and Creative teams to design hypothesis-driven experiments, test attribution models, and iterate quickly based on insights.
• Influence creative production strategy and provide sharp briefs and direction to design and video teams.
• Provide strategic leadership on tracking, attribution, and platform mechanics (CAPI, SKAN, MMM, etc.) to maximize data fidelity and decision-making speed.
• Drive go-to-market execution for new app launches and market entries.

• Mentor and guide junior UA specialists or external agency partners when needed.

   

What We’re Looking For

• 3+ years of experience in performance marketing, ideally with high-budget paid social campaigns in mobile app businesses (iOS/Android/Web2App).
• Deep understanding of platform mechanics (Meta, TikTok auctions, SKAN, CAPI, attribution flows, etc.)
• Track record of scaling spend profitably while maintaining strong unit economics.
• Advanced skills in analytics and experimentation — ability to build your own dashboards and confidently act on insights.
• Comfortable crafting creative strategies and working hands-on with creative teams to deliver winning assets.
• Strong communication and prioritization skills in remote, cross-functional setups.
• English fluency (C1+).

Bonus Points For

• Experience leading UA for subscription-based mobile products.
• Hands-on with analytics tools like Tableau, Amplitude, Looker, and MMPs like AppsFlyer or Adjust.
• Familiarity with Web2Web campaigns, CRM loops, and lifecycle monetization.
• Experience working in high-velocity growth teams or scaling UA operations from <$1M to $10M+ budgets.
