Job Summary
The Oracle Cloud Infrastructure (OCI) Network Administrator designs, implements, and manages secure, high-performance OCI environments with a focus on tenancy architecture, network layers, identity governance, and high-availability infrastructure. This role combines hands-on OCI administration with security hardening, hybrid cloud integration, and disaster recovery planning.
Key Responsibilities
Tenancy & Network Configuration:
Provision and manage OCI tenancy resources, including Virtual Cloud Networks (VCNs), compartments, subnets, route tables, and security lists. Configure storage solutions (Block Volume, Object Storage, File Storage Service) and optimize network traffic flow.
Identity & Access Management:
Set up IAM identity domains, groups, users, and policies. Enforce multi-factor authentication (MFA) and integrate with on-premises Active Directory for hybrid identity management.
Security Hardening:
Implement risk assessment outcomes by configuring OS hardening, Cloud Guard for threat detection, and Vulnerability Scanning Service (VSS). Resolve critical/high-severity security issues and manage certificate renewals.
Infrastructure Administration:
Perform server maintenance, performance tuning, patching, and monitoring. Allocate CPU/memory resources, configure disk partitions, and ensure infrastructure high availability.
Disaster Recovery & HA:
Design and deploy HA architectures using fault domains, availability domains, and load balancers. Implement DR strategies for cross-region replication and failover.
Hybrid Cloud & DevOps:
Integrate OCI with on-premises environments via FastConnect or VPN. Develop tagging strategies for resource governance and collaborate with DevOps teams using CI/CD tools (e.g., Jenkins, Terraform).
Key Knowledge Areas
OCI Core Services:
Tenancy structure, VCN components, storage options (FSS, Block Volume), and network security (firewalls, security lists).
Security Frameworks:
Cloud Guard configurations, VSS workflows, certificate management, and NIST/ISO compliance standards.
OS Administration:
Linux/Windows system management, AD integration, SMB/shared filesystem setup, and vulnerability remediation.
High Availability:
OCI fault/availability domains, load balancer configurations, and DR architectures (active-passive/active-active).
Hybrid Cloud:
Networking models (VPN, FastConnect), resource synchronization, and monitoring/logging services (OCI Metrics, Logging Analytics).
Required Technical Skills
Proficiency in OCI Console, CLI, and Terraform for infrastructure provisioning.
Hands-on experience with:
OCI IAM domain configuration and policy design.
OS hardening for Linux/Windows and security vulnerability remediation.
Cloud Guard, Tenable, VSS, and certificate lifecycle management.
HA/DR implementations using load balancers and multi-region deployments.
Hybrid cloud integration (VPN, FastConnect) and monitoring tools (OCI Monitoring, Prometheus).
Familiarity with DevOps pipelines and CI/CD tools (Jenkins, GitLab CI).
Qualifications
Certifications:
OCI Architect Associate/Professional, Oracle Cloud Infrastructure Certified Network Professional, or equivalent (e.g., AWS/Azure networking certs).
Education:
Bachelor's degree in Computer Science, Information Systems, or related field.
Experience:
3-5 years in cloud administration, including 2+ years focused on OCI.
Preferred:
Experience with security frameworks (NIST, CIS Benchmarks) and hybrid cloud governance models.
