Job Overview:

We are seeking an experienced Mainframe Db2 Database Administrator (DBA) with strong hands-on expertise in IBM Db2 for z/OS to support large-scale, business-critical mainframe environments.
The successful candidate will be responsible for the administration, performance, availability, integrity, maintenance, and recovery of Db2 databases. The role requires close collaboration with application development, systems programming, operations, security, and infrastructure teams.

Essential Job Responsibilities:
 

• Administer and support IBM Db2 for z/OS databases across development, test, and production environments.
• Create, maintain, and manage Db2 objects including databases, tablespaces, tables, indexes, views, and storage-related definitions.
• Perform database maintenance using Db2 utilities such as REORG, RUNSTATS, COPY, RECOVER, LOAD, UNLOAD, CHECK DATA, and REBUILD INDEX. IBM documents these utilities as core mechanisms for maintaining, reorganizing, loading, checking, copying, and recovering Db2 for z/OS data.
• Perform SQL and database performance analysis and tuning, including review of access paths and indexing strategies.

• Support Db2 version upgrades, maintenance, migrations, and modernization initiatives as required.
