Network Administrator

Description

Network, Server, Storage Virtualisation and Maintenance

• Install, configure and maintain network equipment such as switches, routers, firewalls and Wi-Fi devices, and record configuration details for future operational reference.
• Build and support physical servers and related storage components, including SAN and storage tools, and maintain documentation that reflects deployed configurations.
• Configure, administer, review and optimize, Hypervisor environments and high-availability clusters to support system workloads, validating configuration readiness after changes.
• Coordinate infrastructure adjustments with application, network and database teams whenever infrastructure changes affect dependencies, capturing agreed implementation details.
• Support, Setup, and administration of operating systems e.g., Windows, Ubuntu, Suse, Redhat, Linux.
• Support and administration of cloud service, Private cloud, Azure, AWS.GCP, etc

Container Platforms, Modern Infrastructure & DevOps-Oriented Support

• Support Kubernetes and container-based workloads by assisting with setup, configuration and environment preparation aligned with modern deployment approaches.
• Work with DevOps-aligned technical teams to contribute infrastructure components required for rollout and testing, including preparing evaluation environments.
• Participate in POCs and structured technical tests by helping set up, validate and document environment behaviour during evaluation cycles.
• Capture detailed configuration notes and test observations during infrastructure evaluations and collaborate with project and technical leads when refinements are identified.

Monitoring Configuration, Operational Support & Collaboration with NOC

• Configure monitoring for servers, network devices and other infrastructure components and coordinate with the NOC to align alerting and reporting behaviours with operational practices.
• Work with application and database teams to reflect system behaviour in monitoring configurations and make adjustments when test cycles identify inaccuracies or missing data.
• Analyse monitoring observations with technical peers and provide follow-up configuration updates to maintain relevance and accuracy in monitoring views.
• Provide guidance to first-line teams on interpreting infrastructure alerts and reference escalation paths as part of daily operational support.

Backup, Data Protection, Disaster Recovery (DR) & High Availability (HA) Support

• Execute backup tests and maintain records of data recoverability results for supported systems, sharing evidence with relevant teams when required.
• Support backup configurations and data protection routines by making required adjustments and documenting resulting changes.
• Participate in DR and failover exercises by preparing infrastructure views, capturing test observations and reporting behaviors of primary and secondary components.
• Contribute to HA-related setup by adjusting configuration parameters on servers, clusters or connected components in line with the designs reviewed with technical teams.

Documentation, Handover, Communication & Knowledge Transfer

• Produce implementation documentation for infrastructure setups, including configuration details and operational considerations required for ongoing support.
• Prepare handover materials and walk technical or operational teams through the relevant artifacts so responsibilities can be adopted without ambiguity.
• Develop written communications that describe requirements, escalations or decisions and maintain a structured repository where documentation remains current and accessible.
• Train first-line and peer teams on infrastructure processes and monitoring behaviours, providing ongoing guidance to help them understand configurations and support practices.

Planning, Scheduling, Coordination & Change Execution

• Coordinate downtime windows and system change activities by engaging managers, branches and risk teams to communicate the scope and sequence of planned work.
• Plan and track infrastructure tasks alongside operational and project demands and adjust sequences in alignment with senior team leads.
• Organise cross-team change steps, follow up on dependencies and confirm delivery of required actions as part of the infrastructure change lifecycle.
• Maintain meeting agendas, action logs and change calendars related to infrastructure initiatives and distribute updates to ensure alignment across teams.

Cross-Functional & Vendor Collaboration

• Engage with application, network and database teams to gather system requirements and translate these into infrastructure build steps and configuration updates.
• Work with project managers and senior team leads to ensure infrastructure tasks are sequenced correctly within broader solution rollouts.
• Liaise with vendors and external providers to obtain solution requirements, confirm integration considerations and reflect necessary details in infrastructure work.
• Participate in discussions with stakeholders where operational handovers or solution transitions occur and clarify infrastructure details that support the broader technology environment.
