THE ROLE You'll own growth strategy and execution across 3-4 high-growth client accounts, reporting into our Growth Marketing Director. You're measured on the result (cost per customer, volume, growth), not the activity underneath it. You'll be hands-on every day, lead your client relationships, and help Growth Marketing Managers and Executives get better at the craft. WHAT YOU'LL DO

• Lead mobile UA where relevant: Adjust or AppsFlyer, SKAdNetwork, post-IDFA measurement, Apple Search Ads
• Shape creative direction with our studio: hooks, formats and narratives that break through
• Own measurement: server-side tagging, attribution, sound experiments, cohort and LTV analysis
• Be the trusted lead for your clients through monthly performance reviews and quarterly strategy
• Mentor the growth team and help define how we use AI across it WHO YOU ARE
• 4-7+ years in growth marketing, with agency or multi-account experience
• Deep hands-on experience across Meta, Google and TikTok, plus at least one other major channel
• Experienced with tracking, GTM and attribution in a post-IDFA world
