About the role
Ruby Labs is a leading technology company specialising in innovative consumer products across multiple technology sectors. 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/ 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.
Requirements
- 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, direct communicator - presents country strategy, results, and recommendations to stakeholders.
