About this role.
Feedzai is seeking a senior customer-facing software engineer to implement, integrate, optimize, and support its financial-crime prevention platform for enterprise customers. The role combines hands-on Java and SQL development with REST, messaging, event-driven, and file-based integrations. The engineer will lead technical work during implementations, migrations, upgrades, and production go-lives while troubleshooting complex cross-stack issues. Success requires strong distributed-systems and performance-analysis capability, plus the ability to act as a trusted technical advisor to customer engineering teams. The position is remote in Brazil and involves close collaboration with Customer Success, Product Engineering, Product Management, and customers.

Sample interview questions
I would explain the business objective, interface contracts, data transformations, authentication, error handling, and observability. I would also describe how I made the integration resilient through idempotency, retries, dead-letter handling, and monitoring, then quantify the implementation or operational outcome.
I would first establish impact and correlate application metrics, logs, traces, infrastructure signals, and recent changes. I would inspect thread dumps, GC behavior, heap usage, database and downstream dependency latency, then isolate the bottleneck, implement a safe mitigation, and complete root-cause analysis with preventive monitoring or capacity changes.
I start by clarifying the customer's business requirement and identifying whether platform configuration, an integration pattern, or a reusable extension can satisfy it. I avoid unnecessary bespoke code, document trade-offs, align with engineering standards, and escalate product gaps with evidence from the customer use case.
I create a phased plan covering architecture validation, data readiness, integration testing, performance testing, cutover steps, rollback criteria, ownership, and communications. During go-live, I use clear runbooks and real-time monitoring, and afterward I lead stabilization, post-implementation review, and operational handoff.
I would provide a concise, factual update covering customer impact, current status, containment actions, known versus unknown facts, and the next update time. I would avoid speculation, tailor technical depth to the audience, and follow up with a transparent root-cause review and concrete prevention actions.
