Location : Remote** Fulltime        

Job Description Strong Oracle on Azure, Oracle , Azure, Terraform * CI/CD.

• Core Platform & Architecture (Oracle Database@Azure)

Musthave

• Oracle Database@Azure concepts: Understand that Exadata infrastructure runs in Azure datacenters but is managed via OCI control plane and provisioned through the Azure portal (linking an Azure subscription to an OCI tenancy). Know service scope (RAC support, Exadata performance, Azure billing/MACC) and onboarding steps. [docs.oracle.com]
• Provisioning flow: Handson with creating Exadata Infrastructure, VM Clusters, and Databases from the OracleDB@Azure blade; familiarity with supported models (X9M/X11M, and Exascale), quotas/limits, maintenance windows, and regions/AZs. [learn.microsoft.com], [docs.oracle.com], [docs.oracle.com]
• Service nuances vs OCI: IP address reservation differences (e.g., 13 IPs on client subnet vs 3 in OCI), delegated subnet constraints, and how Azure/OCI APIs interplay.

2) Network & Connectivity (Azurefirst, OCIaware) Musthave

• Azure VNet design for OracleDB@Azure: Building delegated subnets (Oracle.Database/networkAttachment), peering/hubandspoke, NSGs, route tables/NVAs (e.g., Azure Firewall), no default internet egress, and splitDNS patterns. [learn.microsoft.com], [learn.microsoft.com]
• Advanced networking features for Database@Azure (regions, registration steps before creating the delegated subnet). [learn.microsoft.com]
• Hybrid connectivity for migration and app access: ExpressRoute/S2S VPN planning, bandwidth/resiliency, and routing inspection through hub NVA. [learn.microsoft.com], [learn.microsoft.com]

3) Security, Identity & Governance Musthave

• Azure RBAC/Policies/Blueprints for Oracle resources in the subscription and resource groups; secure delegated subnets (private only, NSGs, routing through NVA). [learn.microsoft.com]
• Key Vault/Secrets handling for DB credentials, wallet files, and automation pipelines; logging/monitoring via Azure Monitor and Defender for Cloud (often with Azure Arc).

4) Oracle Database & Exadata Administration Musthave

• Exadata fundamentals: Storage cells, ASM, DB nodes, resource management, IORM, patching cycles, and AWRbased performance tuning; experience administering CDB/PDB and RAC in production. [docs.oracle.com]
• Backup/Recovery & HA/DR: RMAN strategies, Data Guard topologies, and cutover playbooks aligned to RPO/RTO; understanding of servicemanaged backup networks for OD@A.

6) Migration Expertise (Critical) Musthave

• Physical & logical migration paths: RMAN, Data Guard, Data Pump, Oracle GoldenGate, and especially Oracle Zero Downtime Migration (ZDM) for minimaldowntime cutovers from onprem Exadata → OD@A. [learn.microsoft.com], [docs.oracle.com]
• Reference blueprints for OD@A migrations with ZDM: network setup, route tables, hub NVA routing to onprem, and stepwise execution.

9) Project & Risk Management (Cutovercritical)

• Automation, Scripting & IaC Musthave
• Scripting & IaC: Azure CLI/PowerShell, ARM/Bicep or Terraform/OpenTofu for consistent provisioning of VNets, delegated subnets, route tables, and OD@A resources (using the Oracle/OD@A examples). [docs.oracle.com]
• Pipelines: CI/CD (GitHub Actions/Azure DevOps) for promotion of infra changes, parameterized deployments, and postprovision validation.
• Monitoring, Capacity & Performance Musthave
• Monitoring: Azure Monitor metrics/logs for network and VM cluster connectivity; OD@A monitoring from Oracle side; alerting on latency/throughput; change windows and patch orchestration awareness. [docs.oracle.com]
• Capacity & performance: Read/interpret AWR and workload characteristics to size OD@A shapes/VM clusters and storage; know inherited region/AZ constraints and VMcluster limits per Exadata infrastructure.

Musthave

• Runbook ownership: Dryruns for migration, backout plan, checkpoint criteria, and incident handling during DNS/app switchover.
• Stakeholder alignment: App owners, network, security, DBA, and business signoff on RPO/RTO and the minimaldowntime objective (e.g., ZDM with Data Guard).
