The tech stack reveals a mobile-first architecture (React Native, iOS, Android, Kotlin Multiplatform) paired with backend financial services infrastructure (SQL Server, PostgreSQL, FastAPI). Current hiring focus is engineering-heavy with emerging data and CRM optimization roles, while active projects cluster around credit origination efficiency, loyalty engagement, and operational automation—suggesting internal friction between legacy microservices and the need to scale fintech risk and customer journey orchestration.

About Dotz

Dotz is a 20+ year-old Brazilian fintech and loyalty platform serving over 50 million consumers. The company operates as a super app where users earn rewards on everyday purchases through partnerships with major retailers, banks, and telecommunications operators, then redeem those rewards as products, services, discounts, or cash back. The platform also offers embedded financial products—digital accounts, credit cards, and personal loans—creating a closed-loop engagement model where transaction activity drives both loyalty accrual and credit origination. Dotz is privately held, based in Brazil, and operates across 201–500 employees.
