Oracle Database Migration Architect

Position: Oracle Database Migration Architect

Location: Remote

Hiring Mode: 12+ Months Contract

Job Description:

This role is focused on operating within an established VMware environment the underlying VCF platform, NSX-T network segments, and gateways will already be in place and managed by a dedicated platform team. You will not be required to design, implement, or manage VCF, NSX-T, or HCX infrastructure. Your core responsibility is ensuring Oracle Database workloads run reliably, are migrated successfully onto the platform, and are configured to VMware and Microsoft best practices.

Responsibilities:

Oracle Database Migration:

• Plan, test, and execute migrations of Oracle Database instances into VMware virtual machines within the existing VCF 9.1 environment
• Perform Oracle workload migrations between virtual machines and across environments with minimal disruption to production services
• Validate data integrity, connectivity, and application compatibility before and after each migration
• Right-size virtual machine configurations (vCPU, memory, storage I/O) based on Oracle Database workload requirements and VMware best practices
• Document migration plans, runbooks, and post-migration validation reports

Oracle Database Configuration & Best Practices on VMware:

• Configure Oracle Database instances and schemas in accordance with VMware and Oracle best practices for virtualized database workloads
• Deploy and manage Oracle Data Guard and Real Application Clusters (RAC) within the VMware virtual environment, including listener configuration, standby management, and failover testing
• Apply VMware-specific Oracle tuning recommendations including NUMA alignment, large memory pages, storage latency settings, and vCPU scheduling
• Assist with Oracle Database performance troubleshooting in the VMware context, working with the platform team where infrastructure-level investigation is required

Day-to-Day VMware Operations:

• Operate confidently within a vSphere 6.7 environment provisioning, cloning, snapshotting, and reconfiguring virtual machines as needed
• Navigate and work within a VCF 9.1 environment, utilizing existing workload domains and pre-configured resources for Oracle VM deployments
• Consume NSX-T virtual network segments and gateways already in place connecting VMs to the correct segments and troubleshooting basic VM-level connectivity issues
• Work with the storage team to present and configure datastores and VMDKs appropriately for Oracle Database performance requirements

Collaboration & Documentation:

• Work closely with DBA, application, and platform teams to coordinate migration windows and post-migration validation
• Produce clear, accurate technical documentation including migration runbooks, VM build standards, and Oracle configuration baselines
• Raise and track infrastructure requests with the platform team for any VCF, NSX-T, or HCX-related changes that fall outside the scope of this role

Required Qualifications:

Experience:

• 4+ years of hands-on experience working in VMware vSphere environments, including vSphere 6.7
• Working knowledge of VMware Cloud Foundation (VCF) 9.1 sufficient to navigate the environment, understand workload domains, and deploy VMs within an existing platform
• Working knowledge of VMware NSX-T understanding of virtual network segments and logical gateway topology; ability to connect VMs to existing segments and diagnose basic connectivity issues (no design or implementation responsibility)
• Proven experience migrating Oracle Database workloads into and within VMware virtual environments
• Hands-on experience with Oracle Data Guard and/or Oracle RAC in a virtualized context
• Solid understanding of Oracle Database configuration best practices on VMware (NUMA, vCPU, memory, storage I/O)

Technical Skills:

• VMware vSphere 6.7 VM provisioning, cloning, snapshots, resource configuration, and vCenter management
• VMware VCF 9.1 workload domain awareness, VM deployment within existing domains (operational, not architectural)
• VMware NSX-T understanding of network segments, T1 gateways, and overlay networking; connecting and troubleshooting VMs at the network edge (no NSX-T design, deployment, or management required)
• Oracle Database (19c, 21c, or 23ai) installation, configuration, migration, Data Guard, RMAN backup/restore
• Oracle migration tooling RMAN, Data Pump (expdp/impdp), GoldenGate, or Transportable Tablespaces
• PowerShell, PowerCLI, and/or shell scripting for routine VMware and Oracle operational tasks

Preferred Qualifications & Certifications:

• VMware Certified Professional Data Center Virtualization (VCP-DCV 2023 or later)
• Oracle Database Administrator Certified Professional (OCP) or equivalent Oracle certification
• Familiarity with VMware Aria Operations (vROps) for monitoring VM and Oracle workload performance
• Experience with storage best practices for Oracle on VMware (thin vs. thick provisioning, VMDK alignment, datastore I/O)
• Exposure to Oracle RAC on VMware, including shared storage configuration and cluster interconnect networking
• Understanding of VMware vMotion, DRS, and HA behavior and how it affects Oracle workloads
• Experience working within ITIL-aligned change management processes in enterprise environments

Additional job information

To set clear expectations, the following activities are explicitly outside the remit of this position and are owned by a dedicated platform team:

• VMware Cloud Foundation (VCF) design, architecture, deployment, or lifecycle management
• NSX-T design, implementation, upgrade, or ongoing management (including routing, micro-segmentation, firewall policy, and VPN)
• VMware HCX deployment, configuration, or management
• SDDC Manager, vSAN, or VCF workload domain administration
