## Description

The Database Administrator will administer, secure, and tune IBM Db2 for z/OS databases while providing secondary support for Microsoft SQL Server and Azure SQL Managed Instance. This role supports mainframe-to-warehouse data pipelines and treats documentation, cross-training, and knowledge transfer as core deliverables.

What You'll Do

 * Database Administration & Design: Review and approve physical database designs (tablespaces, partitioning, indexing). Manage ZPARM, buffer pools, storage allocation, and version-controlled DDL changes via ITIL processes.

 * Performance & Maintenance: Monitor subsystem and thread health. Analyze access paths using EXPLAIN, optimize inefficient SQL, and schedule maintenance utilities (REORG, RUNSTATS, COPY, RECOVER).

 * Backup, Recovery & Security: Own backup strategies, log management, point-in-time recovery, and disaster recovery runbooks. Manage Db2 authorization, roles, and RACF integration under least-privilege principles to satisfy audit requirements.

 * Integration & Operations: Support nightly extract pipelines (unload utilities, SFTP, enterprise scheduling) and DDF/DRDA distributed access. Participate in on-call rotations, maintenance windows, and Db2 version/PTF upgrades.

 * Knowledge Transfer: Maintain runbooks, cross-train backup administrators on critical procedures, and mentor engineering teams on SQL efficiency.
