About this role
Job Description: About the Role We're seeking a Senior Java Developer with 5+ years' experience to build high-performing, scalable enterprise portal backends, APIs, and modern React frontends. You'll develop modular services, cloud-native integrations, and headless APIs for robust, production-ready portal applications. Key Responsibilities
• Develop modular Java backend services (OSGi modules, Service Builder equivalents) and RESTful/GraphQL headless APIs for enterprise portals. • Build responsive React frontends with client extensions consuming portal APIs and state management (Redux/Zustand). • Design and optimize Postgres/MySQL databases with advanced entity-service mappings and SQL performance tuning. • Implement event-driven integrations using message brokers (RabbitMQ, Kafka, Azure Service Bus) for cross-module communication. • Deploy containerized portal applications with Docker/Kubernetes on Azure, ensuring high availability. • Optimize performance with distributed caching (Redis, Hazelcast), low-latency APIs, and frontend bundle optimization. • Collaborate across full SDLC: API contracts, modular development, frontend integration, deployment, and monitoring. • Implement full-stack observability with Prometheus, Grafana, Datadog across backend services and frontend. • Implement DevSecOps with automated security scanning, CI/CD pipelines for modular deployments. Must-Have Skills
• Backend/Portal: Java 17+, Spring Boot, enterprise portal frameworks (OSGi modules, Service Builder, modular service layers); REST/GraphQL headless APIs. • Frontend: React 18+, TypeScript, hooks, component libraries (Material-UI), portal client extensions/API integration. • Architecture: Microservices/modular monoliths, design patterns (CQRS, Event Sourcing, repository patterns). • Agentic Coding: Proficiency with agentic AI coding assistants for rapid prototyping, refactoring complex OSGi modules, and generating tests across full-stack components. • DevOps/CI-CD: Docker, Kubernetes (Helm charts), Jenkins/GitHub Actions, multi-module pipelines. • Cloud: Azure (2+ years hands-on). • Databases: Postgres/MySQL, JPA/Hibernate, advanced SQL, entity-service mappings. • Testing: JUnit/Mockito (backend), Jest/React Testing Library (frontend), integration testing. • Tools: Git, Gradle/Maven (multi-module), npm/yarn. • Full SDLC experience; OWASP security for enterprise applications. Nice-to-Have Skills
• Kafka streaming, Next.js for portal frontends. • Infrastructure as Code (Terraform for portal deployments). • Advanced monitoring: Datadog, Splunk. • Domain-Driven Design, legacy system integration (.NET/mainframes). • Portal-specific patterns: content management, user personalization, workflow engines. Preferred Qualifications
• Bachelor's/Master’s in computer science. • Cloud/Java certifications.
