We are looking for a Head of Revenue Growth. You will own the full revenue engine across a portfolio of mature, monetizing platforms in social discovery and live-streaming, not one funnel, not one channel, but the whole picture. That means P&L accountability, paid acquisition across mobile and web, monetization strategy, product growth experiments, and the unit economics that tie it all together. You will work directly with the CEO, Head of Marketing, Head of DS & AI, and five Product Owners . We move fast, cut through bureaucracy, and give real ownership to people who can handle it. If that sounds like your kind of environment, read on.

About United Tech: We are a global IT product company building the next generation of mobile and web platforms in live-streaming and social networking. Our products connect millions of users across North America, Europe, LATAM, and MENA, and we have been profitable doing it. Founded in Ukraine, operating worldwide, with a market we expect to exceed $206B by 2030. We are not chasing that number, we are already in the middle of it.

In this role, you will

• Own the full revenue funnel and its P&L from acquisition to repeat payments — accountable to ROAS LT0/LT7/LT30 targets and blended payback
• Develop and execute the revenue growth strategy across paid traffic (mobile + web), product growth, and monetization, owning channel mix, budget allocation, and scaling decisions
• Generate, prioritize, and validate growth and monetization hypotheses with Product and Tech, driving prioritization of Product Owner backlogs for growth work
• Lead A/B and multivariate testing across onboarding, activation, paywalls/coin-packs, and pricing
• Own unit economics (CAC, LTV, ARPU, ARPPU, ROAS, payback) and the cohort LTV model; ensure scalable, margin-aware growth given streamer revshare
• Partner with Payments and Risk to maximize payment conversion and approval rates, and expand margin-accretive web/direct billing

• 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
