About The Position

ZipStaff is seeking an Oracle DBA with database-migration depth for a global technology services firm in Houston. You will administer production Oracle estates and plan and execute migrations with Oracle Database Migration Service, GoldenGate, Data Pump, and RMAN. This is a hands-on DBA and cutover seat — not a cloud-architect role and not a SQL-developer role.

Requirements

8+ years Oracle database administration in production.
Oracle RAC, ASM, Data Guard, RMAN, OEM, and SQL performance tuning.
Hands-on Oracle Database Migration Service and at least one completed Oracle database migration.
OCI, Exadata, ExaCC, or another cloud migration.
GoldenGate replication and zero- or minimal-downtime strategies.
Shell, SQL, and PL/SQL scripting.
Ability to work hybrid in Houston, TX (3 days on-site).
Must be legally authorized to work in the United States without sponsorship now or in the future.

Nice To Haves

OCI certification.
Cross-platform migration or database modernization.
AWS RDS for Oracle or Azure Oracle workloads.

Responsibilities

Administer, monitor, and maintain Oracle databases in production and non-production.
Install, configure, patch, upgrade, and run backup and recovery.
Manage Oracle RAC, ASM, Data Guard, RMAN, OEM, and SQL performance tuning.
Plan and execute migrations with Oracle DMS, GoldenGate, Data Pump, and RMAN.
Assess source and target, define the migration strategy, plan cutover, and mitigate risk.
Troubleshoot migration issues, validate consistency, and hold downtime to the agreed window.
Implement HA/DR and support business continuity.
Write migration runbooks, cutover and rollback procedures, and DMS execution plans.
