• Proven experience with database performance tuning, query optimization, execution plans, indexing strategies, and identifying performance bottlenecks.
• Strong SQL skills and a deep understanding of relational database concepts, schema design, transactions, and data integrity.
• Experience managing database availability, replication, backup and recovery, disaster recovery, and business continuity.
• Experience monitoring database health, diagnosing production issues, resolving performance problems, and implementing preventive maintenance.
• Experience administering databases in Linux/Unix environments, including command‑line tools, scripting, and system‑level troubleshooting.
• Understanding of how CPU, memory, storage, I/O, networking, and database configuration affect performance and reliability.
• Experience supporting large‑scale databases, including multi‑terabyte data environments, capacity planning, and growth management.
• Experience administering high‑availability or distributed database systems.
• Experience deploying, operating, or monitoring databases in cloud or containerized environments, including Kubernetes.
• Experience supporting database migrations, upgrades, patching, configuration changes, and platform modernization.
• Ability to develop scripts or tools, preferably using Python on Linux, to automate database administration and operational tasks.
• Strong troubleshooting, analytical, documentation, and problem‑solving skills.
• Ability to communicate technical findings and recommendations to stakeholders and collaborate effectively across engineering teams.

Preferred Qualifications

• Security clearance: Active TS/SCI w/poly
• Certifications: Industry‑recognized certifications like Oracle Certified Professional (OCP), Microsoft Certified: Azure Database Administrator Associate, or AWS Certified Database
• Operating system, networking, storage administration experience highly desired
• Experience administering and supporting multiple database platforms across relational, NoSQL, and distributed database environments.
