About the role

Rappi generates terabytes of daily transactional data and is looking for a Growth E&A Lead who builds the models, dashboards and architectures that turn this data into business decisions. The role leads the Growth team, manages strategic projects and ensures initiatives deliver value to the business.

Key responsibilities

• Lead the design and analysis of A/B tests with high statistical standards, checking for sample ratio mismatch, novelty/primacy effects and biases before rollout
• Investigate sudden drops in core metrics such as retention or conversion, distinguishing technical issues from market behaviour and quantifying GMV loss
• Analyse price elasticity and demand curves to recommend pricing points that balance conversion rate lift against operational costs
• Write high-performance SQL for cohort analysis and data aggregation, and optimised Python scripts (vectorized) for large datasets of 10M+ rows
• Act as a thought partner for Product Managers, challenging assumptions with data and explaining statistical concepts in business terms
• (Optional) design workflows with AI agents or Python scripts to automate anomaly detection and metric monitoring

Required profile

• Bachelor's degree in Statistics, Mathematics, Economics, Computer Science or a related quantitative field
• 3+ years in product analytics, data science or growth, with a focus on A/B testing and causal inference
• Ability to explain why a test succeeded or failed to non-technical stakeholders
• Team leadership, ownership and results orientation

Required skills

• SQL: complex window functions, handling sparsity in cohort retention
• Python with Pandas, Polars and NumPy, understanding of O(N^2) vs O(N) complexity
• Business acumen: LTV, CAC, price elasticity of demand
• Plus: workflow automation (N8N, Airflow) or simple RAG/AI agents
