Role: Senior Network Hand & Feet Engineer (L2/L3 Physical & Logical Support)
Duration of the role: Minimum 1 year, extendable up to 5 years
Onsite
Core Objective
The candidate will be responsible for the end-to-end physical deployment and logical validation of network infrastructure. You will be expected to diagnose issues across Layers 1, 2, and 3 of the OSI model, ensuring that physical connectivity aligns with logical configurations.
1. Advanced Device Racking & Mounting
* Precision Placement: Interpret and execute Rack Elevation Diagrams (REDs) to mount high-density chassis (Cisco Nexus 9k, Catalyst 9500) and 1U/2U appliances.
* Mechanical Safety: Ensure proper use of rack rails, cage nuts, and stabilization kits. Manage weight distribution to maintain rack integrity.
* Power Sequencing: Connect dual-homed power supplies to diverse PDU sources (A+B feeds) and perform "pull tests " to verify seating.
2. Structured Cabling & Fiber Management
* Fiber Optics: Expert-level handling of Single Mode (SMF) and Multi-Mode (MMF) fiber. Proficiency in cleaning connectors (IBC cleaners) and inspecting end‑faces with fiber scopes.
* SFP/Transceiver Management: Correctly identify and install SFP, SFP+, QSFP+, and QSFP28 modules. Troubleshoot "link down " issues by verifying wavelength compatibility (e.g., 850nm vs 1310nm) and light levels.
* Patching & Labeling: Execute high-density patching in accordance with ANSI/TIA-606-B standards. Ensure every cable is labeled at both ends with Near-End/Far-End information.
3. Patch Panels & Cross-Connects
* Circuit Extensions: Coordinate with Telco providers to extend circuits from the Meet‑Me‑Room (MMR) to the local rack via cross‑connects.
* Patch Panel Termination: Manage copper (RJ45) and fiber (LC/SC/MPO) patch panels. Perform "light‑checks " using Visual Fault Locators (VFL) to trace paths through multiple patches.
* Media Conversion: Deploy and troubleshoot media converters or transceivers when transitioning between different physical media types.
* Out‑of‑Band (OOB) Setup: Configure and cable Terminal Servers (e.g., Opengear, Lantronix, or Cisco ISR) to provide permanent remote console access to all managed devices.
* Serial Connectivity: Troubleshoot baud rate mismatches, roll‑over cables, and DB9‑to‑RJ45 adapters to ensure the NOC has a reliable "backdoor " during outages.
* Local Support: Be prepared to connect locally via laptop and serial‑to‑USB adapters to provide a "live stream " of boot sequences or BIOS-level troubleshooting.
5. Advanced Routing & Switching Knowledge
* L1 Fundamentals: Strong working knowledge in Ethernet, Gigabit Ethernet, Serial, fiber cabling, transceivers (Arista, Cisco SFP+, QSFP+), SFP, PIC, NIM, HA ports, power supplies, patching and troubleshooting, with knowledge of DWDM and experience in handling 10/20/40 Gig Fiber links.
* L2 Fundamentals: Configure and troubleshoot VLANs, VTP, and Spanning Tree Protocol (STP), Port mirroring, packet captures. Must understand how to identify and resolve broadcast storms or physical loops at the rack level.
* L3 Fundamentals: Assist in the bring‑up of Layer 3 interfaces (SVIs and Routed Ports). Basic knowledge of prefix lengths and IP addressing to verify gateway connectivity.
* Protocol Verification: Use CLI commands to verify BGP and OSPF neighbor adjacencies after physical circuit hand‑offs or cross‑connect installations.
* EtherChannel/LACP: Provision and troubleshoot Link Aggregation Groups (LAGs). Ensure that physical cabling matches the logical member‑port configuration on the switch.
Required Experience & Skills
* Experience: 6–8 years in a Data Center or large Enterprise campus environment.
* Ethernet, Fiber cabling, Hardware: Experience in installation of Ethernet, fiber cabling on Cisco, Arista and Palo Alto, F5 load balancers and its associated components like SFP, PIC, NIM, DPC.
* Routing and Switching: Ability to navigate Cisco IOS, NX‑OS, PAN OS or Arista EOS to perform show commands and basic interface configurations.
* Tools: Proficiency with Visual Fault Locators (VFL), Light Meters, and Fiber Inspection Scopes.
* Certifications: CCNA or equivalent is mandatory; CCNP Enterprise (ENCORE) is highly preferred to demonstrate routing and switching proficiency.
* Experience in handling mission‑critical network incidents/problems in Enterprise network large campus networks and Data center, is preferred.
* Need to be proficient in English and local language in countries like Switzerland, Germany, Austria, Slovenia, China and Japan.
