About the Role
As a Senior Java Developer, you will lead the design, development, and modernisation of complex software systems using Java and advanced frameworks. You will play a pivotal role in platform modernisation efforts, utilising the strangler migration pattern to transition legacy systems to modern, cloud-native architectures on AWS. Collaborating with cross-functional teams, you will deliver robust, scalable solutions, and mentor team members to ensure technical excellence. Experience with Kotlin would be highly advantageous.
Key Responsibilities
- System Design and Development: Architect and implement high-performance, scalable applications using Java, Spring Framework, Spring WebFlux, Spring Cloud, JOOQ, Spring R2DBC, and Liquibase. Incorporate Kotlin where applicable to enhance development efficiency.
- Platform Modernisation: Lead platform modernisation initiatives using the strangler migration pattern to incrementally replace legacy systems with modern, cloud-native solutions.
- Event-Driven Architecture: Design and develop event-driven systems using Kafka and Debezium for real-time data streaming and integration.
- Microservices and Orchestration: Build and deploy microservices using Kubernetes, Docker, and Istio for service mesh management.
- Authentication and Authorisation: Implement secure authentication and authorisation mechanisms using Keycloak.
- Workflow Automation: Utilise Conductor OSS to design and manage complex workflows for business processes.
- Data Management: Leverage Redis for caching and high-speed data access, ensuring optimal application performance.
- Performance Monitoring: Use New Relic to monitor application performance, identify bottlenecks, and optimise system efficiency.
- Code Quality and Reviews: Write clean, maintainable, and well-documented code in Java and potentially Kotlin, and conduct thorough code reviews to ensure quality, security, and adherence to standards.
- Collaboration: Work closely with Product Manager, Business Analysts, Architects, and ITS teams to define technical requirements and deliver robust solutions.
- Mentorship: Provide technical guidance and mentorship to junior developers, fostering a culture of continuous improvement.
