Design, develop, and maintain Java‑based micro‑services for transaction processing. 2. Implement REST APIs and messaging interfaces that adhere to ISO 8583 and ISO 20022 standards. 3. Collaborate with business owners, testing teams and external vendors to gather requirements and ensure smooth delivery. 4. Participate in Agile ceremonies, sprint planning and backlog grooming. 5. Write unit, integration and performance tests to guarantee code quality. 6. Contribute to CI/CD pipelines using tools such as Jenkins, GitLab CI and Docker. 7. Deploy and monitor services on Pivotal Cloud Foundry (PCF) or other cloud platforms. 8. Assist in database design and optimisation using RDBMS or modern NoSQL stores. 9. Engage in code‑review processes and mentor peers on best practices. 10. Support production incidents and perform root‑cause analysis for continuous improvement. The tech stack revolves around Java 11+, Spring Boot, Spring Cloud, REST, messaging queues (Kafka/RabbitMQ), relational databases (PostgreSQL, Oracle), and cloud platforms like PCF. Familiarity with containerisation (Docker, Kubernetes) and CI/CD tools is highly valued.
