  • Support Layer 2/3 network deployment and validation, including VLANs, routing protocols (OSPF, BGP), and basic security policies under engineer supervision.
  • Respond to high-priority infrastructure outages with rapid on-site resolution, documenting root cause and preventive actions for SLA compliance.
  • Coordinate with remote network operations center (NOC) and vendors for escalation, parts delivery, and configuration handoff to ensure minimal downtime.
