Containerized Deployment: Develop and deploy Java applications within containerized environments (e.g., Docker, Kubernetes), and ensure smooth continuous integration and delivery (CI/CD) processes.
Performance Optimization: Troubleshoot, debug, and optimize the performance of high-volume, enterprise-level applications, particularly in a banking or financial context.
Agile Methodology: Participate in Agile ceremonies, contribute to sprint planning, and collaborate with team members to deliver quality software on time.
API Development: Develop, test, and document APIs; define swagger specifications, and collaborate with front-end developers and other API consumers.
Collaboration & Problem Solving: Work closely with other developers, solution engineers, and stakeholders to design and implement innovative solutions, taking ownership of assigned tasks and delivering results efficiently.

Essential Qualifications:
Matric / Grade 12 / National Senior Certificate (mandatory)
B-Degree in Computer Science or related technical field (preferred)

Minimum Experience & Skills:
10+ years of experience in Java application programming and development
5+ years of experience with the Spring Framework (Spring Boot, Spring Batch, etc.)

Strong background in object-oriented design and application architecture
Experience with SOA, Microservices Architectures, and integration protocols (e.g., SOAP/XML, REST, JSON, MQ)
Experience deploying Java applications in orchestrated container environments (e.g., Docker, Kubernetes)
Proven expertise in high-volume environments, particularly in banking (e.g., clustering, session management, multi-threading)
Hands-on experience with DevOps practices and tools (e.g., Jenkins, SonarQube, Nexus, Git)
Knowledge of Cloud Technologies, ideally AWS or Azure
Experience with Database Management (e.g., optimizing queries, DB2, relational databases)
