Job Title: Oracle Database Migration Subject Matter Expert (SME)
Location: Remote
Job Type: 12 mths plus contract
Experience Level: Senior / Principal

Rate - 80-100 hour DOE

About the Role

We are seeking an expert Oracle Database Migration Subject Matter Expert (SME) to architect and execute a massive infrastructure modernization initiative. In this role, you will lead the migration of 20+ Oracle Exadata and Exadata Cloud@Customer (ExaCC) appliances to an Open Systems architecture running Oracle RAC on Linux with high-performance NVMe storage.

This is a high-visibility, mission-critical project. The ideal candidate will have extensive, hands-on experience dismantling Exadata-specific dependencies and successfully re-platforming enterprise-scale workloads using Oracle GoldenGate and Oracle Data Guard.

Key Responsibilities

Migration Architecture: Design, validate, and execute zero-downtime and near-zero-downtime migration strategies for 20+ Exadata/ExaCC appliances.
Replication & Synchronization: Configure, monitor, and tune Oracle GoldenGate for cross-platform logical replication alongside Oracle Data Guard for physical synchronization and switchover pipelines.
Feature De-engineering: Identify and remediate Exadata-specific features (e.g., Smart Scans, Hybrid Columnar Compression, Storage Indexes) to ensure optimal performance on commodity Open Systems.
Platform & Storage Optimization: Configure and optimize database workloads transferring from Exadata storage cells onto open-systems NVMe-based storage arrays (including ASM disk group configuration).
Cluster Deployment: Build, secure, and tune highly resilient Oracle RAC environments on standard enterprise Linux distributions.
Performance Validation: Perform rigorous pre- and post-migration performance benchmarking (using AWR, ASH, and SPA) to guarantee SQL workloads translate smoothly to standard compute fabrics.

Required Technical Skills & Qualifications

Scale Experience: Proven history of successfully driving large-scale database migrations (20+ enterprise-scale appliances or hundreds of databases).
Migration Tooling Mastery: Expert-level hands-on experience deploying Oracle GoldenGate and Oracle Data Guard / Broker configuration.
Oracle Grid & RAC: Advanced knowledge of Oracle Grid Infrastructure, Clusterware, Automatic Storage Management (ASM), and Real Application Clusters (RAC).
Database Versions: Deep hands-on experience administering, patching, and maintaining Oracle Database 19c (specifically 19.30c / 19.31c).
Exadata Deconstruction: Extensive production experience administering and decomposing Oracle Exadata and ExaCC platforms.
NVMe & Storage: Solid understanding of configuring Oracle ASM over high-performance NVMe storage devices or enterprise fabrics.
Linux Expertise: Deep understanding of Linux OS kernel tuning (huge pages, network stack optimization) specifically tailored for Oracle RAC.

Preferred Qualifications

Oracle Certified Professional (OCP) or Oracle Certified Master (OCM) certification.
Strong automation scripting skills (Shell, Python, or Ansible).
