Ensure auditability, traceability, and strong monitoring for payment systems
Collaborate with product, architecture, and platform teams
Drive engineering excellence through code reviews, testing, and CI/CD
Required Skills
Strong hands-on experience in Java and microservices architecture
Experience with Kubernetes-based platforms (IKP or similar)
Good understanding of Service Mesh concepts (mTLS, routing, sidecars)
Knowledge of microservices patterns (DDD, API versioning, backward compatibility)
Experience with Kafka or similar messaging systems
Familiarity with observability tools (logging, tracing, metrics)
Preferred Skills
Spring Boot or Quarkus
Docker and Kubernetes
API tools like OpenAPI/Swagger
Security: OAuth2, JWT, mTLS
CI/CD pipelines and automated testing
Performance and contract testing tools
Payments Domain Experience
Understanding of payment processing flows (validation, routing, reconciliation, exceptions)
