RecargaPay operates a multi-product fintech platform serving over 10 million Brazilians, with a Python + Java + Kafka + Databricks tech backbone handling payments, investments, and lending. The company is actively modernizing legacy infrastructure while adopting AI-assisted engineering (GitHub Copilot, Cursor) and building marketing analytics capabilities (MMM, incrementality frameworks, A/B testing) — a pattern indicating simultaneous pressure to improve operational velocity and attribution precision. Engineering-heavy hiring (13 roles) alongside finance (6) reflects dual priorities: scaling backend systems and tightening financial controls.
