Job description

What the role is:

The jobholder is responsible for a hands‑on technical lead to manage the mission‑critical infrastructure that powers MHA/HTX operations. In this role, you will not just oversee systems; you will be the technical authority ensuring the availability, security, and performance of enterprise‑wide server and network ecosystems. If you thrive in complex environments involving Network, Active Directory, Shared Storage, and Hybrid Cloud networks, and prefer getting your hands dirty with technical problem‑solving over pure administrative oversight. Details are as follows.

What you will be working on:

• Hands‑On Infrastructure Management: Directly manage and maintain enterprise services including Network equipment, Active Directory, File/Application Servers, Hypervisors, and Storage systems. Ensure optimal performance of network connectivity and server availability.
• System Life‑Cycle Engineering: Drive the end‑to‑end lifecycle of ICT systems—from technical evaluation and procurement to deployment, patching, sustainment, and eventual refresh/migration.
• Technical Problem Solving: Serve as the Tier‑3 escalation point for complex server and network incidents. Troubleshoot high‑priority issues to minimize downtime for user operations.
• Vendor & Warranty Management: Technical ownership of vendor deliverables. Validate that systems in warranty/maintenance phases meet rigorous performance specifications before handover.
• Security & Compliance: Implement and enforce security best practices (system hardening, GPO management). Lead technical remediations for IT audits and compliance checks.

What we are looking for:

• Tertiary qualification in Electrical Engineering, Computer Science, IT, or related technical disciplines.
• Minimum 5 years of hands‑on working experience in system/ network administration, infrastructure architecture, or cloud operations.
• Proven track record in maintaining 24/7 operational systems with strict SLAs and rapid response times.
• Proactive self‑starter capable of driving technical projects with minimal supervision.
• Deep Knowledge of Active Directory, Group Policy Objects (GPO), Domain Controllers, File/App Servers, and Patch Management.
• Hands‑on experience with Hypervisors (VMware/Hyper‑V/Nutanix) and designing/operating large‑scale private/public cloud infrastructure.
• Management of Shared Storages (SAN/NAS), Backup Appliances, and understanding of enterprise networking concepts (VLANs, Load Balancing, Routing, Firewalls) required for systems interconnectivity.
• Experience conducting and remediating IT/Compliance Audits. Strong grasp of cybersecurity frameworks and system hardening.
• Proficiency with ITSM tools (e.g., ServiceNOW) and Systems Engineering lifecycle management.

All new hires are appointed on a two‑year contract in the first instance and will be assessed and considered for permanent tenure over time, based on performance.
