Serve as a senior escalation point for production outages and performance degradation across EBS application and database tiers.
Diagnose and resolve blocking sessions/deadlocks, contention scenarios (including concurrent SQL + maintenance activities), and restore services with clear validation steps.
Execute planned maintenance windows end-to-end: pre-checks, change execution, post-validation, and stakeholder communication.
Oracle EBS database maintenance & reorganization
Lead Oracle EBS DB reorganizations (multi-phase execution), including stakeholder coordination, execution planning, and service restoration communication.
Perform and troubleshoot index rebuilds/reorg activities, recover from failures, and implement safer sequencing to avoid deadlocks and downtime.
Own operational best practices for tablespace/FRA/TEMP/UNDO monitoring and proactive space management.
Security hardening, risk, and compliance support

password profiles and policies, hashing, auditing controls

Act as the DBA point of contact for Risk, Audit, and Security inquiries:
justify/remediate privileged access (including ANY privileges)
execute RFC-based privilege removals and exception renewals
implement Oracle-recommended DB profiles and security baselines
Health checks, runbooks, and operational documentation
Author and maintain EBS health check documentation covering DB + EBS operational areas (sessions, CM, tablespaces, FRA, blocking sessions, etc.).
Build/maintain runbooks for production support, maintenance validation, and recurring operational tasks.
Create/maintain procedural guides (e.g., server access request process) to reduce friction and improve auditability.
Oracle Support & vendor coordination
Own the lifecycle of Oracle SRs, tickets, and RFCs; act as liaison between Oracle Support, internal teams, and vendors (including reporting tools).
Provide clear technical evidence (logs, test results, reproducibility steps) and drive issues to closure.

Core Platform Responsibilities (role Baseline)

Oracle EBS administration (R12.1 / R12.2)
Administer and support Oracle EBS R12.2 application + database tiers with strong command of:
Autoconfig, tech stack maintenance, web tier checks
Concurrent Manager monitoring/tuning
ADOP cycle execution & troubleshooting, patching readiness and failure recovery
cloning/refresh procedures and post-clone validation
Database operations (HA/DR/backup/performance)
Administer Oracle DB platforms supporting EBS (including 19c), with strong capability in:
RAC, Data Guard, RMAN (backup/recovery strategy, execution, validation)
performance tuning using AWR/ADDM, SQL tuning, indexing strategies
production-grade monitoring and capacity management
Upgrades & patching
Plan and execute:

EBS upgrades (12.2.x lifecycle)
DB upgrades (e.g., 19c)
patching (CPU/PSU, tech stack, EBS/DB) with disciplined rollback planning

OCI Operations

Support OCI-hosted EBS/DB workloads including DBaaS, IaaS, and Exadata (Gen1/Gen2); perform cloud-side maintenance and operational tasks (patching, connectivity/service configuration, compute shape changes, etc.). (Capability strongly aligned to senior profiles in the candidate pool. )

Required Qualifications

6+ years of Oracle DBA experience with strong Oracle EBS Apps DBA exposure (R12.1/R12.2), including patching/ cloning/ autoconfig/ adop troubleshooting.
Demonstrated production support ownership: incident diagnosis, stability improvements, maintenance execution, and post-change validation.
Strong hands-on expertise in RAC, Data Guard, RMAN, and Oracle DB administration (11g19c).
Proven ability to work across teams and communicate clearly during outages and maintenance windows.

Preferred Qualifications (highly Valued)

Deep experience running Oracle EBS on OCI (DBaaS/IaaS/Exadata) and performing cloud-side operational tasks and patching.
Strong EBS R12.2 upgrade history and significant ADOP troubleshooting experience.
Experience with Enginatics Blitz Reporting support (connection strings, standby routing/service names) and vendor coordination (aligned to the operational needs you listed).
