Requisition ID: 63451 Position: Database Administrator 3 We are looking for senior-level database administrator with advanced expertise in both Oracle and PostgreSQL, along with a deep understanding of database architectures, security principles, and performance tuning methodologies. The candidate should also have strong problem-solving skills, attention to detail, and the ability to work under pressure while managing multiple complex database systems. The candidate must also be willing to participate in a rotational 24x7 on-call Production Support. 1. Database Installation and Configuration Install, configure, and maintain Oracle Multi-Tenant Architecture and PostgreSQL database servers. Set up instances, database parameters, and schema objects. Perform upgrades and patch management to ensure databases are up-to-date with the latest features and security patches. Experience Red Hat Linux Operating Systems. 2. Database Architecture and Design Collaborate with development teams to design and implement efficient, scalable database solutions. Create database structures, including tables, views, indexes, and constraints. Define data storage, indexing strategies, and partitioning schemes for optimal performance. 3. Database Performance Monitoring and Tuning Monitor database performance and system resource utilization to ensure high availability. Identify bottlenecks, analyze slow queries, and tune databases for optimal performance. Utilize tools like Oracle AWR, PostgreSQL pg_stat_statements, and other performance analysis tools. Implement performance improvements such as indexing, query optimization, and caching mechanisms. 4. Backup and Recovery Implement and manage backup and disaster recovery strategies (e.g., RMAN for Oracle, pg_dump for PostgreSQL). Ensure data integrity and availability through regular backups and replication. Perform recovery tasks in the event of database corruption or failure. 5. Security Management Configure and maintain database security, ensuring appropriate user permissions and roles are in place. Encrypt sensitive data, ensure secure connections, and apply security best practices. Monitor for potential security threats and resolve vulnerabilities in both Oracle and PostgreSQL environments. 6. Capacity Planning and Scalability Analyze and forecast future database storage requirements. Plan for scalability, ensuring the databases can handle increasing workloads and data growth. Optimize database storage and processing capabilities, balancing performance with cost. 7. Data Migration and Integration Perform data migrations between Oracle, PostgreSQL, and other databases. Develop and manage ETL (Extract, Transform, Load) processes for data movement and transformation. Ensure data consistency and integrity during migration and integration efforts. 8. High Availability and Clustering Implement and manage high availability solutions such as Oracle Data Guard Replication, RAC and PostgreSQL streaming replication or clustering. Configure failover mechanisms to minimize downtime in case of hardware or software failure. 9. Database Troubleshooting and Issue Resolution Resolve database-related incidents such as connectivity issues, slow performance, and data corruption. Provide technical support to development and operations teams for database-related problems. Perform root cause analysis and implement preventive measures. 10. Automation and Scripting Automate routine database administration tasks using scripts (e.g., Bash, PowerShell, PL/SQL for Oracle, PL/pgSQL for PostgreSQL). Develop automation tools for monitoring, backups, and performance tuning. 11. Collaboration and Documentation Work closely with development, DevOps, and infrastructure teams to support application and system requirements. Document database configurations, processes, and procedures. Provide training and mentoring to junior DBAs or development teams on database best practices. 12. Compliance and Auditing Ensure databases comply with relevant regulatory standards (e.g., GDPR, SOX, HIPAA). Regularly audit database security, usage, and access logs. Manage and maintain database audit trails and security logs. 13. Innovation and Continuous Improvement Stay current with new database technologies, tools, and techniques. Propose and implement improvements to database systems, increasing efficiency, performance, and security. -- Keywords: information technology procedural language Idaho PostgreSQL Database Administrator 3 [email protected] |
