Monitoring network health, performing trend analysis, tuning network systems, and identifying improvements. Contributing to documentation, knowledge-sharing, and mentoring within the technical team. Managing change, incident, and problem-management practices, including stakeholder communication and vendor engagement. Acting proactively: not just “fixing things,” but identifying root causes, mitigating risks, leading enhancements, and strengthening the network. Participating in the on-call roster and supporting disaster recovery and business continuity activities as required. What We’re Looking For – Essential 5 years’ experience in network operations and support within a large or complex environment. 2 years’ experience managing Linux systems, including patching and overall management.
