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.
• Proficiency with common toolsets: console servers, terminal emulators, basic automation/scripting exposure, and ticketing systems.
• Strong documentation habits and attention to detail in asset/port records.
