Role summary |
Senior hands-on network technician responsible for advanced installation, turn-up, troubleshooting, and validation of data center network infrastructure under engineering direction. |
Key responsibilities |
Perform advanced switch/router installation and turn-up tasks: rack/stack, power-up, console access, image validation, baseline configuration, and feature enablement per runbooks. |
Execute L2/L3 troubleshooting using structured methods (interface counters, logs, spanning-tree, VLANs, Layer 3 adjacency checks) and resolve complex incidents during build windows. |
Validate physical and logical connectivity: optics selection, fiber polarity verification, link aggregation, VLAN trunking, and end-to-end ping/trace tests. |
Lead staging and burn-in activities; coordinate maintenance windows and support change implementation with accurate documentation. |
Mentor L1/L0 technicians; review work for correctness (labeling, patching, port mapping) and enforce ESD/tooling best practices. |
Update as-built network records (port maps, serials, rack elevations, IP allocations) in the designated system of record. |
Required skills and knowledge |
Strong understanding of CCNA-level networking concepts: IP addressing, VLANs, trunking, STP, EtherChannel/LAG, Layer 3 fundamentals (static routes, OSPF basics), and troubleshooting. |
Hands-on familiarity with data center cabling and optics: SFP/SFP+/QSFP form factors, fiber types (SM/MM), polarity, and connector care. |
Ability to follow and improve runbooks/MOPs; disciplined change control and rollback planning. |
