In this role, you will

• Build revenue dashboards and a single source of truth for performance metrics, with shared metric definitions and transparency across teams

   

It's all about you

• Strong hands-on experience in growth / performance marketing for dating, social discovery, live-streaming, or IAP products, across both mobile apps and web funnels
• Demonstrable strong command of unit economics (CAC, LTV, ARPU, ARPPU, ROMI, payback, contribution margin) — able to build the model, not just read it
• Proven experience scaling paid acquisition on mobile and web: Google, Meta, TikTok, and programmatic/DSP (e.g., Moloco) are a strong advantage
• Solid experience with A/B testing, experimentation frameworks, and funnel optimization
• Strong analytical foundation: SQL and BI tools (e.g., Looker/Tableau), cohort analysis, predictive LTV; working knowledge of mobile attribution/MMP (AppsFlyer/Adjust), web analytics and server-side tracking (GA4, Meta CAPI), web2app deep-linking, and incrementality testing
• Experience managing growth, marketing, or media-buying teams

• Deep hands-on experience with Meta Ads, from strategy to daily optimization

• Confident working with BI tools such as Tableau, Power BI, or Looker Studio
• Experience automating buying processes through auto-rules, scripts, or custom tools
• A track record of scaling campaigns without losing efficiency
• Understanding of Tier-1 markets (US, CA, UK) and highly competitive niches
• Upper-Intermediate English or higher
• Active use of AI tools in daily work, with the ability to write clear prompts and critically evaluate results, applying AI to at least two areas: data analysis and insight generation, creative hypothesis generation and copywriting, or automation of routine tasks

• Experience with transactional or credit-based monetization models
• Experience mentoring or building a team from scratch
