Senior Administrator - Network LAN/WAN
Shanghai, Shanghai
Job Summary
Job Summary : Owns the day-to-day physical health of the Client\'s office, lab, and network-room (IDF/MDF/NER) infrastructure at the assigned site. This is the hands-on, onsite execution layer of the service: incident response, Layer 1 diagnosis and repair, structured cabling moves/adds/changes, hardware installation, preventive maintenance, and asset accuracy. The role is deliberately distinct from desktop/end-user support — the scope is facility and network infrastructure, not user devices.
Job Description : na
Key Responsibilities
Job Responsibilities : Network room and facility operations Provide day-to-day support for IDF/MDF/NER network rooms, ensuring hardware, power, and cooling systems are functioning correctly. Conduct preventive maintenance and scheduled inspections of network room equipment, cable plant, and environmental systems to minimise unplanned downtime. Perform regular audits of network rooms and lab spaces: identify undocumented changes, remediate cable management, remove abandoned cable, and reconcile asset records. Monitor and report on rack-level and room-level power utilisation; escalate thermal or capacity exceptions. Layer 1 troubleshooting and break/fix Diagnose and resolve physical-layer network faults, including cable faults, connector integrity, patch panel verification, port negotiation failures, transceiver compatibility, and signal degradation across copper and fibre media. Perform fibre optic testing and certification using OTDR and optical light meters; produce and file test results. Troubleshoot and maintain server and storage hardware (Dell, HPE, Lenovo, SuperMicro) — component replacement, firmware/BIOS-level triage, RMA coordination. Respond to monitoring alerts, escalations, and incidents within agreed SLA targets; drive incidents to closure with clear resolution notes. Installation and smart hands Rack, stack, cable, and de-install network, compute, and storage equipment with appropriate lifting assistance. Install, configure, and connect smart PDUs and UPS units; validate redundant feeds and correct circuit loading. Execute structured cabling moves, adds, and changes to specification; terminate and dress copper and fibre. Support lab infrastructure requests and provide remote-hands assistance to Network, AV, and End User Support teams. Documentation and change control Maintain accurate network room and asset records in Netbox/Nautobot via UI updates and bulk import. Update port, patch, and circuit documentation as part of every change — documentation is a completion criterion, not an afterthought. Log all work in ServiceNow and Jira with accurate time, category, and resolution coding to support reporting and trend analysis. Support regional power shutdown events: pre-shutdown checks, controlled shutdown/restart sequencing, and post-event validation.
Skill Requirements
Skill Requirement : Associate degree or technical diploma in IT, electronics, or a related field, or equivalent hands-on experience. 4+ years supporting physical network, server, or structured cabling infrastructure in an enterprise, lab, or data-centre environment. Demonstrated Layer 1 troubleshooting capability across copper and fibre, including test-equipment proficiency (OTDR, optical power meter, cable certifier). Working knowledge of network fundamentals — TCP/IP, DNS, DHCP, VLANs, switch port configuration concepts — sufficient to isolate physical vs. logical faults. Practical understanding of rack power distribution, PDU/UPS operation, circuit capacity, and network room cooling principles. Experience with ticketing systems (ServiceNow, Jira) and asset/DCIM tooling (Netbox, Nautobot, or equivalent). Physically able to lift and install rack-mounted equipment with assistance, work in confined network room spaces, and use ladders and lifts safely. Clear written and verbal English; able to produce concise incident notes and site reports. PREFERRED BICSI Installer 2 / Technician certification, or comparable vendor cabling certification (Panduit, CommScope, Corning). Experience in a hyperscale, semiconductor, or large-scale technology campus environment. Familiarity with monitoring and provisioning tooling (MAAS, environmental monitoring platforms). Basic scripting or SQL for bulk asset updates and reporting. SERVICE MEASURES Incident response and resolution within agreed SLA thresholds. Preventive maintenance schedule completed on plan. Asset and port documentation accuracy verified at audit. Zero unplanned outages attributable to cabling or power work performed by the team.
