Network Consultant

Location:

WEEHAWKEN, NJ

Responsible for performing read-only logical discovery, connectivity validation, and data collection across data center network devices. The role involves logging into network devices to capture system status, interface and connectivity details, and accurately documenting findings in customer-provided discovery templates.

The engineer works closely with physical audit and field teams to correlate logical data with physical labels, cabling, and rack placement using network and data center management tools. Per the customer guideline, the role also supports post-move and post-relocation validation, ensuring devices power on correctly, retain expected connectivity, and rejoin clusters, fabrics, or HA pairs without configuration changes.

• Perform secure, read-only login to network tools to perform the logical assessment/audit into the documents and update the tools based on the physical audit report.
• Good understanding vendor equipment like Cisco, Juniper, or next-gen firewalls.
• Create and update network diagrams
• Installation & Deployment:
  Managing the physical setup of hardware, including racking and stacking servers, running copper and fiber cabling, and configuring network devices like switches and routers
• Validate logical device identity, including hostnames, management IPs, and alignment with physical labels.
• Capture interface and connectivity details, including:
• Link status (up/down)
• Speed and duplex where visible
• MAC and IP addresses (IPv4/IPv6)
• VLAN or subnet association (status-only)
• Validate logical connectivity indicators such as:
• Basic reachability tests (ping/trace route where permitted)
• MAC and ARP table entries
• Neighbor visibility (LLDP/CDP)
• Populate and validate customer-provided discovery templates with accurate logical data, including:
• Device names and management IPs
• Interface identifiers, MAC/IP details, and link status
• Cross-check logical findings against physical audit data from field teams.
• Identify and report discrepancies such as:
• Incorrect hostnames or labeling
• Missing or inactive interfaces
• Support post-move validation by:
• Confirming successful power-on
• Validating interface enumeration and connectivity consistency
• Escalate post-move issues such as unreachable devices, missing links immediately.
• Follow all customer security, credential handling, access control, and audit logging policies.
• Maintain high standards of documentation accuracy and template discipline.

• Ability to safely perform read-only login to network and data center management tools.
• Hands on expertise and experience with data center physical layer, racking and hardware maintenance.
• Familiarity with data center infrastructure, fiber optics, and networking hardware.
• Familiarity with out-of-band and management interfaces.
• Strong understanding of:
• Network interfaces, link behavior, VLANs, and basic L2/L3 concepts
• MAC, IP, ARP, and neighbor discovery
• Ability to interpret status and “show” commands and extract required audit values.
• Strong capability to correlate logical data with physical network.
• Exceptional attention to detail and accuracy in template-based documentation.
