We are seeking a highly skilled and experienced Senior Java Developer to join our team. The ideal candidate will have hands-on experience in migrating monolithic Java applications across diverse infrastructure environments.

This role is instrumental in the end-to-end migration of legacy applications from traditional data centres to modern VM-based infrastructure.

The successful candidate will collaborate closely with cross-functional teams including Infrastructure, Application Development, Integration, and Security to ensure seamless migration outcomes.

  • Analyse and refactor application configurations, deployment scripts, and system services.
  • Collaborate with teams to configure firewalls, TLS, and Java-layer deployments.
  • Design and maintain CI/CD workflows using GitHub, Azure DevOps, and Artifactory.
  • Integrate and maintain AppDynamics for real-time JVM performance monitoring.
  • Document migration steps, rollback procedures, and test cases in Confluence.
  • Collaborate during test planning and execution to validate infrastructure stability and application performance.
  • Track progress, risks, and testing efforts using Jira.
About You

We are looking for an individual with:

  • At least 7+ years of professional experience with Java (8+), Spring Boot, JPA/Hibernate, and REST APIs.
  • Practical experience deploying applications using Embedded Tomcat in Linux VM environments.
  • Proven ability to re-engineer or re-platform legacy Java workloads.
  • Solid understanding of web service protocols: REST, SOAP, SFTP, and scheduled jobs.
  • Experience working with financial messaging protocols such as SWIFT or ISO 20022.
  • Strong troubleshooting skills across distributed systems.
  • Experienced working in DevOps-driven environments with CI/CD pipelines, version control, and automated deployments.
  • Demonstrated experience working in Agile Scrum teams with regular sprint deliverables.
  • Excellent verbal and written communication; strong documentation habits.
  • Team-focused with a proactive mindset and a passion for continuous improvement.
  • Strong analytical and problem-solving mindset.
  • Ability to work independently and manage priorities in fast-paced and dynamic environments.
Nice to Have

We welcome candidates with experience in:

  • Puppet for configuration management.
  • Familiarity with ELK stack (Elasticsearch, Logstash, Kibana) for logging and monitoring.
