Descripción de la vacante

Unisys is seeking a Senior Oracle DBA to strengthen day-to-day support of Oracle databases on Linux/Unix. You will install, configure, maintain, back up and recover databases, and lead vulnerability fixes to reduce risk and improve performance.

You will mentor the team, drive uptime, apply patches, ensure security compliance, and contribute to Oracle database projects when capacity allows.

Formación

• BA/BS degree and 6–8 years’ relevant experience, or an equivalent combination of education and experience.
• Strong hands-on Oracle DBA experience in enterprise production environments.
• Proven experience patching Oracle (OPatch, Release Updates, Critical Patch Updates) and fixing vulnerabilities.
• Experience with backup and recovery (RMAN) and high availability (RAC, Data Guard).
• Solid Linux/Unix skills, with scripting and automation experience [Bash, SQL, PL/SQL].
• Experience with incident, problem and change management (ITIL or similar).

Responsabilidades

• Provide day-to-day support for Oracle Database environments [Oracle 19c, RAC, ASM, Data Guard], including installation, configuration, upgrades, maintenance and performance tuning.
• Lead vulnerability fixes for Oracle databases: review scan findings, prioritize by risk, apply Release Updates and quarterly Critical Patch Updates, and make configuration and hardening changes.
• 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
