This role offers high visibility, technical ownership, and significant opportunity to shape how we serve our global institutional clients.

Responsibilities:

• Lead the hands-on architecture, design, and development of mission-critical, high-throughput microservices using modern Java (Java 17/21), Spring Boot, and RESTful/event-driven APIs
• Architect and implement robust event-driven workflows and real-time streaming data pipelines using Apache Kafka (producers, consumers, partitions, schemas, and fault-tolerant message processing)
• Design and implement highly concurrent, low-latency solutions utilizing advanced multithreading, concurrency patterns, and JVM performance tuning
• Write clean, testable, maintainable, and secure code following modern software engineering best practices, design patterns, and enterprise security standards
• Lead end-to-end SDLC activities from architectural design, technical specification, and implementation through to automated testing, CI/CD pipeline integration, and production deployment
• Design and optimize data persistence layers across relational databases (Oracle, PostgreSQL) and NoSQL/document stores (MongoDB) ensuring data integrity, optimized indexing, and efficient querying
• Continuously monitor, profile, and optimize application performance, reliability, and resilience using distributed tracing, metrics, and observability tools
• Partner with Solution Architects, Product Owners, and cross-functional engineering teams to define system enhancements, evaluate technical trade-offs, and deliver complex business workflows
• Investigate, troubleshoot, and resolve high-impact technical challenges in distributed production environments, leading root-cause analyses and permanent remediation
• Provide technical leadership, establish coding standards, conduct comprehensive peer code reviews, and mentor mid-level and junior developers across the team

Qualifications:

• Minimum 10+ years of hands-on enterprise Application Development experience with strong backend engineering expertise
• Deep, expert-level proficiency in Core Java (Java 11/17/21), object-oriented design, collections, memory management, and multithreading/concurrency models
• Extensive hands-on experience building and deploying production-grade microservices using the Spring ecosystem (Spring Boot, Spring Data JPA/Hibernate, Spring Security, Spring Cloud)
• Strong hands-on expertise with Apache Kafka and Event-Driven Architecture, including topic design, consumer groups, offset management, message serialization, and event streaming patterns
• Proven experience in designing, building, securing, and versioning scalable RESTful APIs
• Strong database skills working with relational databases (e.g., Oracle, PostgreSQL) including query optimization, indexing, and transactions, as well as document stores (e.g., MongoDB)
• Solid understanding of distributed systems principles, caching strategies, and resilient design patterns (Circuit Breaker, Saga, Outbox, Retry/Backoff)
• Hands-on experience with automated unit and integration testing frameworks (JUnit 5, Mockito, Testcontainers)
• Familiarity with containerization and cloud platforms (Docker, Kubernetes / Red Hat OpenShift) and modern CI/CD deployment pipelines
• Exposure to Kotlin is a significant advantage
• Demonstrated technical leadership, excellent analytical and debugging skills, and strong verbal and written communication abilities
