📋 Description

• Lead the architecture of real-time fraud-decisioning services that score transactions, logins, and account changes within sub-second SLAs. • Own the fraud rules engine, including rule versioning, shadow/canary rollouts, and analyst testing tools. • Partner with Data Science to productionize fraud-detection models through low-latency feature pipelines and serving infrastructure. • Design Kafka event-driven pipelines for transaction, device, and behavioral signals with ordering, idempotency, and exactly-once guarantees where required. • Build audit trail and explainability layers for fraud decisions to support regulators, card networks, and dispute teams. • Mentor engineers and champion coding, system design, and incident-response best practices. • Solve high-scope, complex, ambiguous technical problems involving financial exposure. • Promote AI-assisted engineering practices using code generation, automated refactoring, and technical documentation tools.

🎯 Requirements

• Academic background oriented toward computer science, engineering, or software development disciplines. • Track record of success in hands-on backend engineering roles, developing with Java, Spring Boot, PostgreSQL, Kafka, and AWS. • Experience designing or operating real-time decisioning, scoring, or rules-engine systems under strict latency budgets. • Hands-on experience with fraud, risk, or trust & safety systems — e.g. transaction scoring, device fingerprinting, velocity/anomaly detection, or chargeback and dispute pipelines. • Solid understanding of event-driven architectures and streaming data (Kafka), including ordering, idempotency, and exactly-once semantics. • Knowledge of relational database systems, Object-Oriented Programming, and Domain-Driven Design; familiarity with microservice architecture is a plus. • Ability to translate compliance and audit requirements (e.g. BACEN, LGPD, PCI-DSS) into resilient, explainable system design. • Experience conducting code reviews, driving knowledge sharing, and promoting collaborative development practices. • Proven ability to design complex distributed applications built for high performance, throughput, scalability, and reliability. • Practical experience applying AI frameworks in development projects. • Experience in Python is a plus. • Strategic thinking and problem-solving, with a proactive approach to closing technical and process gaps before they turn into losses. • High degree of autonomy and accountability, capable of leading technical decisions with minimal supervision, even under financial and regulatory pressure. • Proven mentorship capabilities, fostering the growth of junior and mid-level engineers. • Strong communication skills, able to explain fraud-engineering trade-offs to both technical peers and Risk/Compliance stakeholders. • Comfortable navigating ambiguity. • Demonstrated influence in shaping engineering practices and elevating team-wide technical standards. • Alignment with company values: ownership, excellence, adaptability, and innovation.

🏖️ Benefits
