  • Practical experience with Oracle GoldenGate for data replication and real-time data integration across distributed environments.
  • Working knowledge of Unix and shell scripting to support database automation, environment management, and operational tasks.
  • Experience with Agile and Scrum delivery frameworks and familiarity with CI/CD tooling including Jenkins, Bitbucket, Jira, and deployment automation platforms.
  • Bachelor's degree in a relevant field or equivalent professional experience.


Beneficial Skills & Qualifications
