This role is responsible for the end‑to‑end physical deployment, cabling, validation, and first‑level logical verification of network devices and connectivity.

You will act as the primary on‑site escalation point for remote Network Engineering and NOC teams, ensuring that Layer 1 implementation aligns accurately with Layer 2 and Layer 3 configurations in highly available, mission‑critical environments.

Key Responsibilities

Advanced Device Racking and Mounting

  • Interpret and execute Rack Elevation Diagrams (REDs) for high‑density network devices such as Cisco Nexus 9000, Catalyst 9500, firewalls, and load balancers.
  • Perform safe installation using appropriate rack rails, cage nuts, and stabilization kits, ensuring correct weight distribution and rack stability.
  • Connect and validate dual‑power supplies across redundant A/B PDUs, including pull tests and power sequencing checks.

Structured Cabling and Fiber Management

  • Handle Single‑Mode (SMF) and Multi‑Mode (MMF) fiber in accordance with data center best practices.
  • Clean and inspect fiber connectors using IBC cleaners and fiber inspection scopes.
  • Install and troubleshoot SFP, SFP+, QSFP+, and QSFP28 transceivers, validating wavelength compatibility and optical light levels.
  • Execute structured patching and labeling in line with ANSI/TIA‑606‑B standards, ensuring accurate near‑end and far‑end identification.

Patch Panels and Cross‑Connects

  • Coordinate with data center and telecom providers to extend circuits from Meet‑Me Rooms (MMR) to local racks.
  • Terminate and manage copper (RJ45) and fiber (LC, SC, MPO) patch panels.
  • Perform fiber tracing and continuity checks using Visual Fault Locators (VFL).
  • Support media transitions using media converters or mixed‑media transceivers where required.

Remote Management and Console Access

  • Deploy and cable Out‑of‑Band (OOB) management solutions (e.g. Opengear, Lantronix, Cisco ISR).
  • Troubleshoot serial connectivity issues including baud rate mismatches, rollover cables, and DB9‑to‑RJ45 adapters.
  • Provide local laptop and serial access during incidents to support live troubleshooting, boot monitoring, and BIOS‑level diagnostics.

Routing and Switching Fundamentals

  • Layer 1: Strong hands‑on experience with Ethernet, fiber cabling, transceivers, power supplies, HA ports, and high‑speed links (10G / 20G / 40G), with exposure to DWDM environments.
  • Layer 2: Support VLANs, VTP, Spanning Tree Protocol (STP), port mirroring, and packet captures. Identify and mitigate physical loops or broadcast storms.
  • Layer 3: Assist with Layer 3 interface bring‑up (SVIs and routed ports), basic IP addressing, and gateway connectivity validation.
  • Protocol Verification: Validate BGP and OSPF neighbor adjacencies following circuit hand‑offs or cross‑connect installations.
  • EtherChannel / LACP: Provision and troubleshoot Link Aggregation Groups, ensuring physical cabling aligns with logical configurations.

Experience

Required Experience and Skills

  • 6–8 years of experience in data center or large enterprise campus network environments.
  • Hands‑on experience installing and supporting Cisco, Arista, Palo Alto, and F5 network platforms.
  • Experience supporting mission‑critical network incidents in enterprise or data center environments.
  • Basic German
