Job Description
Technically lead the real-time decision architecture: ensure that the integration layer with risk engines responds within the transaction SLA window, without creating exposure between the call trigger and the decision return.
Responsibilities
- Build REST APIs for the engine and integrations with third parties (anti-fraud, AML, score).
- Implement resilience: timeout, retry, circuit breaker, and idempotency.
- Develop asynchronous producers and consumers for post-decision actions.
- Model transactional and event data in relational databases and NoSQL.
- Maintain automated tests, load tests, and CI/CD pipelines.
- Instrument technical and business metrics (decision time, block rate).

- Has the firmness to say no when deadlines or scope do not align, always bringing a concrete alternative

- Expertise in event-driven distributed systems architecture, with a clear understanding of when to use synchronous patterns (transaction decision) and when to use asynchronous patterns (post-decision actions: log, case, Coaf, analytics)
- Design of APIs (REST/gRPC) and API Gateway to integrate multiple external anti-fraud, AML, KYC, and score engines
- Low-latency architecture with critical SLA: transaction decision within a few hundred milliseconds, without leaving a window of exposure to fraud
- AWS Cloud: containers, queues, gateway, observability (logs, metrics, distributed tracing)
- Senior Backend in a robust language (Java, Python or Node, according to the defined stack)
- Information security applied to payments: encryption, tokenization, PCI-DSS best practices
