• Keep databases compliant with security policies and hardening standards [CIS Benchmarks, DISA STIGs], including user and privilege management, auditing and encryption.

• Work with Security teams to review Oracle security alerts, determine which databases are exposed, and plan fixes within agreed timeframes.

• Resolve complex database incidents and problems, perform root-cause analysis and put permanent fixes in place to improve availability and reliability.

• Keep services resilient through tested backup, recovery and high-availability setups [RMAN, Data Guard].

• Handle incidents, problems and changes through ITSM processes and meet service level agreements.

• Mentor and coach team members, sharing knowledge and documented procedures so the team relies less on escalations.

• Plan and carry out database upgrades, migrations and patch cycles with minimal service disruption.

• Develop and maintain scripts and automation [Bash, SQL, PL/SQL, Ansible] to streamline patching, vulnerability fixes, health checks and routine database tasks.

• Evaluate, recommend and maintain database monitoring and management tools [Oracle Enterprise Manager].

• Contribute to Oracle database projects, capacity planning and service improvements as capacity permits.

• Explain technical issues and risks clearly to non-technical stakeholders.

• Maintain documentation, runbooks and knowledge articles
