The company focuses on D2C (Direct-to-Consumer) subscription products. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/ ### About the role We are looking for a Senior User Acquisition Manager to own and scale Facebook(Meta) for one of our core D2C subscription products. The funnel is simple: ad → quiz → trial → subscription (web-to-web). The scale is not: 40+ countries, 20+ languages, one of the largest Meta budgets in its category. You will be measured on two numbers: daily subscriptions and cohort ROI — not clicks, not CTR, not platform-reported ROAS. You'll operate with serious leverage: an API-driven build pipeline and AI tooling handle the mechanical work. Your job is judgment — what to scale, what to cut, where the next dollar goes. The bar is high and so is the upside: performance here is directly and significantly rewarded, and strong operators take on bigger scope fast. ### Key Responsibilities Channel Ownership: Own the Facebook account end to end — structure, budgets, bidding, geo mix — keeping subscription volume high at target CPA and ROI. Scaling & Stability: Scale winners without breaking CPA; keep delivery stable at high spend and catch problems before they cost money. Testing: Run a continuous testing pipeline — creatives, structures, bidding (highest volume / cost cap / bid cap), placements, geos and languages. Kill fast, scale what works. Creative Ideas: Own the creative direction for the channel — hooks, angles, formats — and brief the creative team with data-backed feedback. Working with Data: Make decisions on real cohort revenue from our BI, not on Ads Manager numbers. Break performance down to country × creative × bid level and build your own reports. Account Health: Protect ad accounts, pages and Business Managers — policy-safe copy and landings, appeals, backups. AI & Automation: Automate every repeatable part of your workflow with AI and keep manual work to a minimum. ### Qualifications ### Must-Have Experience 2+ years hands-on Facebook as the primary channel you personally owned. Personally owned $400K+/month on Meta with direct accountability for CPA / ROI targets — your budget, not your team's or agency's total. Subscription funnels: drove subscriptions or trials through web funnels (web-to-web) or subscription apps for D2C products. Multi-GEO: ran and scaled campaigns across many countries and languages at once. Analytics: comfortable with cohorts, LTV, payback and the gap between platform and BI numbers. AI in daily work: uses Claude, ChatGPT or equivalents daily for analysis, reporting and automation — not just aware of them. Working proficiency in English (B2+). ### Not a Fit Mostly agency experience (spread across many small clients) E-commerce / catalog-only background (DPA, Shopping, basket ROAS) ### Who You Are Full owner of your zone — from diagnosis to result, no reminders needed Analytical — every scale or kill decision has a period, a threshold and a dollar amount behind it Plans ahead — runs the channel against a plan weeks and months out Fast under load — many campaigns and tests in parallel without quality slipping Ambitious — wants to grow fast and prove it with performance ### Location Ruby Labs operates within the CET (Central European Time) zone.
