Project and Initiatives Summary:

The resource will work remotely and will collaborate with US-based teams across time zones. The project involves developing and modernizing cloud-native microservices architecture for our digital authentication and fraud prevention platform. This initiative is part of our broader digital transformation strategy to migrate legacy monolithic applications to a scalable, resilient microservices ecosystem on Azure Cloud. The resource will play an integral role in designing, developing, and deploying high-performance, mission-critical services that handle millions of transactions daily across our digital channels. Top Responsibilities:

• Design and develop RESTful microservices using Java 17+ and Spring Boot 3.x framework
• Implement distributed data models and optimize queries for Apache Cassandra clusters handling high-volume transactional data
• Build and deploy cloud-native applications on Microsoft Azure using AKS (Azure Kubernetes Service), Azure Functions, and Azure Service Bus
• Develop event-driven architectures using Kafka or Azure Event Hubs for real-time data streaming
• Implement API gateways, service mesh (Istio), and container orchestration using Kubernetes
• Write comprehensive unit tests using JUnit 5, Mockito, and integration tests for microservices
• Collaborate with cross-functional teams, including DevOps, QA, Security, and Product teams in an Agile/Scrum environment
• Troubleshoot production issues, perform root cause analysis, and implement resilient solutions with proper monitoring and alerting
• Maintain technical documentation, including architecture diagrams, API specifications (Swagger/OpenAPI), and runbooks
• Participate in code reviews, ensure adherence to secure coding practices, and optimize application performance
• Proactively identify technical debt and areas for improvement, providing innovative solutions aligned with best practices

• 10+ years of hands-on experience with Java (Java 8+, preferably Java 17) and object-oriented design principles
• Strong expertise in Spring Framework ecosystem, especially Spring Boot: Spring Boot, Spring Cloud, Spring Data, Spring Security, Spring REST
• Production experience with Apache Cassandra: data modeling, CQL queries, partition strategies, replication, and performance tuning
• Azure Cloud Platform: Azure Kubernetes Service (AKS), Azure Container Registry, Azure Key Vault, Azure Monitor, Application Insights
• Microservices architecture patterns: Circuit Breaker (Resilience4j), API Gateway, Service Discovery, Distributed Tracing
• Containerization and orchestration: Docker, Kubernetes, Helm charts
• Message-driven architectures: Kafka, RabbitMQ, or Azure Service Bus
• CI/CD pipelines: Jenkins, Azure DevOps, GitLab CI, or GitHub Actions
• Database expertise: NoSQL (Cassandra, MongoDB) and relational databases (PostgreSQL, Oracle)
• Version control and collaboration: Git, GitLab/GitHub, code review practices
• Monitoring and observability: Prometheus, Grafana, ELK Stack, Splunk, or Azure Application Insights
• Strong understanding of RESTful API design, OAuth 2.0, JWT authentication, and API security best practices
• Experience with Agile/Scrum methodologies and tools like Jira, Confluence

• Strong English communication skills for collaborating with US-based teams Preferred Skills:

• Experience with Apache Kafka Streams or event sourcing patterns
• Knowledge of CQRS (Command Query Responsibility Segregation) and Event-Driven Architecture
• Experience with reactive programming using Spring WebFlux or Project Reactor
• Experience in financial services or banking domain, particularly authentication, fraud prevention, or payment systems
• Familiarity with DevSecOps practices and security scanning tools (SonarQube, Snyk, Veracode)
• Knowledge of service mesh technologies (Istio, Linkerd)
• Experience with GraphQL APIs
• Strong analytical and problem-solving skills with the ability to work independently
• Excellent communication skills and ability to articulate complex technical concepts to both technical and non-technical stakeholders
• Experience working with globally distributed teams across multiple time zones
