• Coordinate with Network, Storage, VM, DCFM, GIS, and application teams to resolve infrastructure dependencies, cabling issues, firewall, DNS, and load balancer requirements.
• Monitor build progress, manage technical blockers, and ensure servers are provisioned according to committed timelines.
• Conduct daily build status calls, provide progress reports, and coordinate with GBT/GMET teams on technical issues and delivery risks.
• Support application setup requirements, GIS onboarding, security compliance, commissioning, and warranty activities.
• Lead GIS handover activities and ensure server environments are ready for application deployment.

Requirements

• Diploma or Degree in IT, Computer Science, or a related discipline.
• Relevant experience in Linux administration, server provisioning, infrastructure engineering, or server build operations.
• Hands-on experience with Linux OS installation, configuration, troubleshooting, user management, and system hardening.
• Good understanding of networking fundamentals, including DNS, firewalls, load balancers, IP addressing, and connectivity troubleshooting.
• Experience coordinating with Network, Storage, VM, Data Centre, Security, and application teams.
• Familiarity with JIRA, vulnerability remediation, infrastructure documentation, and server handover processes.
• Strong troubleshooting, communication, coordination, and stakeholder management skills.
