Server, Storage Virtualisation and Maintenance\nInstall, configure and maintain network equipment such as switches, routers, firewalls and Wi-Fi devices, and record configuration details for future operational reference.\nBuild and support physical servers and related storage components, including SAN and storage tools, and maintain documentation that reflects deployed configurations.\nConfigure, administer, review and optimize, Hypervisor environments and high-availability clusters to support system workloads, validating configuration readiness after changes.\nCoordinate infrastructure adjustments with application, network and database teams whenever infrastructure changes affect dependencies, capturing agreed implementation details.\nSupport, Setup, and administration of operating systems e.g., Windows, Ubuntu, Suse, Redhat, Linux.\nSupport and administration of cloud service, Private cloud, Azure, AWS.GCP, etc\nContainer Platforms, Modern Infrastructure & DevOps-Oriented Support\nSupport Kubernetes and container-based workloads by assisting with setup, configuration and environment preparation aligned with modern deployment approaches.\nWork with DevOps-aligned technical teams to contribute infrastructure components required for rollout and testing, including preparing evaluation environments.\nParticipate in POCs and structured technical tests by helping set up, validate and document environment behaviour during evaluation cycles.\nCapture detailed configuration notes and test observations during infrastructure evaluations and collaborate with project and technical leads when refinements are identified.\nMonitoring Configuration, Operational Support & Collaboration with NOC\nConfigure monitoring for servers, network devices and other infrastructure components and coordinate with the NOC to align alerting and reporting behaviours with operational practices.\nWork with application and database teams to reflect system behaviour in monitoring configurations and make adjustments when test cycles identify inaccuracies or missing data.\nAnalyse monitoring observations with technical peers and provide follow-up configuration updates to maintain relevance and accuracy in monitoring views.\nProvide guidance to first-line teams on interpreting infrastructure alerts and reference escalation paths as part of daily operational support.\nBackup, Data Protection, Disaster Recovery (DR) & High Availability (HA) Support\nExecute backup tests and maintain records of data recoverability results for supported systems, sharing evidence with relevant teams when required.\nSupport backup configurations and data protection routines by making required adjustments and documenting resulting changes.\nParticipate in DR and failover exercises by preparing infrastructure views, capturing test observations and reporting behaviors of primary and secondary components.\nContribute to HA-related setup by adjusting configuration parameters on servers, clusters or connected components in line with the designs reviewed with technical teams.\nDocumentation, Handover, Communication & Knowledge Transfer\nProduce implementation documentation for infrastructure setups, including configuration details and operational considerations required for ongoing support.\nPrepare handover materials and walk technical or operational teams through the relevant artifacts so responsibilities can be adopted without ambiguity.\nDevelop written communications that describe requirements, escalations or decisions and maintain a structured repository where documentation remains current and accessible.\nTrain first-line and peer teams on infrastructure processes and monitoring behaviours, providing ongoing guidance to help them understand configurations and support practices.\nPlanning, Scheduling, Coordination & Change Execution\nCoordinate downtime windows and system change activities by engaging managers, branches and risk teams to communicate the scope and sequence of planned work.\nPlan and track infrastructure tasks alongside operational and project demands and adjust sequences in alignment with senior team leads.\nOrganise cross-team change steps, follow up on dependencies and confirm delivery of required actions as part of the infrastructure change lifecycle.\nMaintain meeting agendas, action logs and change calendars related to infrastructure initiatives and distribute updates to ensure alignment across teams.\nCross-Functional & Vendor Collaboration\nEngage with application, network and database teams to gather system requirements and translate these into infrastructure build steps and configuration updates.\nWork with project managers and senior team leads to ensure infrastructure tasks are sequenced correctly within broader solution rollouts.\nLiaise with vendors and external providers to obtain solution requirements, confirm integration considerations and reflect necessary details in infrastructure work.\nParticipate in discussions with stakeholders where operational handovers or solution transitions occur and clarify infrastructure details that support the broader technology environment.\nRequirements\nMinimum Requirements: Work Experience and Education\n5 years of experience in working with enterprise-grade network infrastructure.\nProven experience in administering, and automation in large scale out networks and infrastructure\nExperience working in a high-availability environment where 99.9% uptime is critical.\nDiploma or Degree in
