You will install, configure, maintain, back up and recover Oracle databases, and troubleshoot their performance, on Linux and Unix. You will lead the fixing of database vulnerabilities, improve incident resolution and service resilience, and help the team rely less on escalations. When operational capacity permits, you will also contribute to Oracle database projects and service improvements.

Key Responsibilities

• Provide day-to-day support for Oracle Database environments [Oracle 19c, RAC, ASM, Data Guard], including installation, configuration, upgrades, maintenance and performance tuning.

• 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
