Is This Role For You?
- You've shipped growth experiments in fintech or high-velocity tech and proven 10%+ retention/LTV gains
- You live in SQL, A/B test methodology, and statistical rigor—no vanity metrics allowed
- You thrive translating messy data into business stories and selling hypotheses to skeptical stakeholders
- You want ownership of a full retention/engagement funnel, not just campaign execution
- You speak Portuguese or are willing to work in Portuguese-speaking teams (helpful but not required)
- You've only done email marketing or CRM automation without deeper growth experimentation and LTV optimization
- You prefer dashboards over diving into raw data—you need to code or query, not just click buttons
- You need remote flexibility—this is full on-site in São Paulo
- You're new to fintech and uncomfortable navigating credit risk, regulatory nuance, or financial products
