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 launch and own Brazil for one of our core D2C subscription products. We are not present in Brazil yet — you will open the market from zero and own everything that follows: our presence and subscription volume across all paid sources, local ad networks alike. The goal is explicit: take Brazil from launch to a seven-figure monthly budget. This is a hands-on role suited for someone who has already launched or scaled Brazil at large scale and deeply understands the Brazilian audience and advertising landscape. You are expected to make independent, data-driven decisions, present a clear weekly country strategy, and deliver consistent, predictable growth — performance instability and unresolved issues are not acceptable. The bar is high and so is the upside — performance here is directly and significantly rewarded, and strong operators take on bigger scope fast. RESPONSIBILITIES COUNTRY OWNERSHIP & GROWTH - Launch Brazil as a new market and own its subscription volume and growth targets across all paid sources. - Define and execute the country strategy — channels, audiences, creatives, and measurement — scaling to a seven-figure monthly budget. - Own budget allocation across channels, ensuring efficient CAC and positive ROAS. - Prepare and present a clear weekly country strategy with results and next steps. CHANNEL & LOCAL-NETWORK STRATEGY - Run and optimise campaigns across global platforms active in Brazil. - Identify, test, and scale Brazilian local ad networks and traffic sources beyond the global platforms. - Own relationships with local platforms and vendors that move the country's volume. AUDIENCE & CREATIVE LOCALISATION - Use deep knowledge of the Brazilian audience to define angles, offers, and creative briefs. - Work closely with the creative team to produce Brazil-specific creatives in language, culture, and format. - Continuously test and iterate localised creatives and messaging based on performance. ANALYTICS & PERFORMANCE - Build custom performance models, analyses, and reporting in Excel, Tableau, and Mixpanel. - Drive efficient CAC and positive ROAS with growth plans grounded in LTV:CAC and ARPU. - Partner with the data team to apply attribution insights to country-level scaling decisions. QUALIFICATIONS MUST-HAVE EXPERIENCE - 3+ years of hands-on paid user acquisition for D2C subscription products (web-to-web). - Proven track record launching and scaling Brazil as a market, with ownership of country-level targets and results. - Experience managing $100k+ in monthly ad spend with clear ROI accountability. - Hands-on experience with Brazilian local ad networks and traffic sources beyond the global platforms. - Deep knowledge of the Brazilian audience — segments, messaging, and creative codes that convert. - Fluent Brazilian Portuguese plus working English for stakeholder communication. - Advanced Excel skills plus proficiency in Tableau and Mixpanel — you build your own performance models and frameworks. OPERATING ATTRIBUTES - Results-driven with full accountability for the country's performance, regardless of source mix. - Highly analytical — every budget, scaling, and kill decision is grounded in data, not intuition alone. - Autonomous and proactive — runs the market with minimal oversight and surfaces opportunities before being asked. - Fast under load — runs multiple channels, tests, and reporting streams in parallel without letting quality slip. - Clear, d
