Growth Business Analyst

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Growth Business Analyst based in Brazil.

Join a high-growth fintech environment where data, experimentation, and technology are central to how growth decisions are made.

You’ll help drive the performance of paid acquisition channels such as Meta, Google, and TikTok while taking ownership of analytical strategy and optimization.

The role combines quantitative analysis, User Acquisition expertise, automation, and applied AI to increase both acquisition efficiency and scale.

You’ll have autonomy to own channels, identify new growth opportunities, and establish analytical foundations for emerging paid media platforms.

Working closely with the Growth team, you’ll turn performance data into clear hypotheses, experiments, and actionable recommendations.

You’ll also bring external benchmarks and modern acquisition frameworks to continuously raise the standard of paid media operations.

This is an opportunity to make a measurable impact in a fast-moving, data-driven environment while helping shape a rapidly scaling growth function.

Accountabilities:

• Take end-to-end analytical ownership of paid media channels including Meta, Google, and TikTok, covering performance analysis, test hypotheses, optimization routines, and responsibility for both efficiency metrics such as pCAC/ROAS and acquisition volume.
• Structure and lead the analytical setup for new acquisition channels such as Kwai and DSPs, using external benchmarks and market insights to accelerate decisions and unlock growth opportunities.
• Build and continuously improve AI agents and automation workflows that accelerate paid media analysis and operations, including recurring reporting, anomaly alerts, data extraction, and internal Growth tools.
• Establish scalable processes and analytical frameworks that increase the speed and rigor of experimentation across the paid acquisition operation.
• Bring proven User Acquisition practices and frameworks into the team, including account structures, measurement and incrementality, creative testing cycles, and other approaches that can improve performance.
• Translate complex performance data into clear recommendations, defend hypotheses with evidence, and proactively identify opportunities for optimization and growth.
• Work as an autonomous partner within the Growth organization, taking ownership of specific channels and contributing to a fast-paced environment where processes are continuously being built and improved.

Requirements:

• Proven experience in User Acquisition and Paid Media, with a track record of managing meaningful budgets across at least one major channel such as Meta, Google, TikTok, or DSPs and successfully scaling investment while maintaining efficiency.
• Strong quantitative reasoning and fluency in acquisition metrics including CAC/pCAC, ROAS, CPM, and CVR across different stages of the funnel.
• Ability to independently investigate performance using spreadsheets, SQL, BI tools, or similar analytical technologies without relying heavily on other teams for basic analysis.
• Practical, hands-on use of AI in day-to-day work, combined with genuine interest in building AI agents and automation that improve analytical and operational efficiency.
• Strong ownership mindset, with the ability to take responsibility for a channel, establish processes, define priorities, and operate autonomously in an evolving environment.
• Excellent communication skills and the ability to turn analysis into clear recommendations, support hypotheses with data, and bring relevant market benchmarks and external perspectives to the team.
• Experience launching new acquisition channels such as Kwai, DSPs, or programmatic advertising from the ground up is a strong advantage.
• Knowledge of measurement and incrementality methodologies such as geo tests, Marketing Mix Modeling (MMM), or holdouts, as well as experience with Mobile Measurement Partners such as AppsFlyer or Adjust, is desirable.
• Experience with automation tools such as n8n or Zapier, Python scripting, or the development of AI agents is an additional advantage.

Benefits:

• Compensation positioned at the higher end of the market.
• Annual learning budget to support continuous professional development.
• 100% remote work within Brazil.
• Health insurance fully covered for the employee and dependents up to 18 years old, with 50% of the monthly premium covered for spouses and partners.
• Childcare assistance for children up to 6 years old.
• Meal allowance through Caju.
• Flexible vacation policy.
• Wellhub and Zenklub benefits.
• Opportunity to join a high-growth, profitable environment with significant ownership and direct impact on the growth function.
• Exposure to strategic growth challenges, advanced data-driven acquisition practices, AI-powered automation, and experienced fintech operators.
• Opportunity to contribute to expanding financial access for Brazil’s micro and small businesses through scalable financial solutions.
