Role Summary

Looking for an experienced OCI Administrator with 8–10 years of experience in IT infrastructure and cloud administration, including strong hands-on experience in Oracle Cloud Infrastructure (OCI). The candidate should have practical expertise in provisioning, configuring and managing OCI infrastructure, with a strong focus on cloud networking, security, IAM and infrastructure automation using Terraform.

The role requires a good understanding of OCI architecture and the ability to independently provision and manage cloud resources such as VCNs, subnets, compute instances, storage, gateways, load balancers and related networking components. The candidate should also have hands-on experience implementing OCI security policies, managing access controls, configuring network security and monitoring the overall security posture of the environment.

The administrator will work closely with application, database, network and security teams to support infrastructure deployments, troubleshoot complex issues and ensure the availability, security and smooth operation of OCI environments.

Key Responsibilities

OCI Infrastructure Administration

• Manage compartments, resource tagging, quotas, service limits and other tenancy-level configurations.

• Use Terraform and OCI Resource Manager to provision infrastructure and maintain reusable configuration.

• Support infrastructure changes, deployments and maintenance activities in line with the agreed change process.

Security and Access Management

• Manage OCI IAM users, groups, policies, dynamic groups, compartments and access permissions, following least-privilege principles.

• Implement and review network security controls, including NSGs, security lists, private subnet access, bastion connectivity and firewall rules.

• Work with OCI Vault for encryption keys and secrets, and ensure that sensitive information is handled securely.

• Review security findings from services such as Cloud Guard, Security Zones, Audit and Vulnerability Scanning, and coordinate remediation.

• Support security reviews and maintain required access records, configuration details and audit evidence.

Operations, Monitoring and Troubleshooting

• Monitor OCI resources and services and investigate alerts, availability, capacity and performance-related issues.

• Use OCI Logging, Monitoring, Events and Notifications to support operational monitoring and issue diagnosis.

• Troubleshoot compute, operating system, network, storage and access-related incidents, and document the root cause and resolution.

• Coordinate backups, restores, patching and disaster recovery activities; participate in recovery exercises when required.

• Maintain infrastructure documentation, operating procedures and support handover notes.

Platform and Team Support

• Provide infrastructure support for application deployments and migrations to OCI.

• Support OKE clusters, node pools, worker nodes and OCI Container Registry (OCIR) where the project requires it.

• Coordinate with application, database, DevOps, network and information security teams to resolve dependencies and operational issues.
