Network Engineer

The Network Field Engineer is responsible for the onsite implementation, validation, and troubleshooting of enterprise Wi‑Fi and LAN infrastructure within data center environments. This role requires strong hands‑on expertise in wireless networking, switching, and system integration, with a focus on execution quality, performance optimization, and rapid issue resolution.

The engineer works closely with project managers, design engineers, and customer teams to ensure deployments meet design intent, operational requirements, and defined performance KPIs.

• Validate field conditions against design documentation (floor plans, rack layouts, RF designs)
• Conduct site surveys, measurements, and documentation when required
• Capture field updates including photos, markups, and design changes

• Perform staging, configuration, and deployment of:
  • Wireless access points, controllers, and cloud‑managed WLAN systems
  • LAN switching infrastructure (access and distribution layers)
• Execute network configurations including VLANs, routing, segmentation, and security
• Support installation teams with technical direction and quality validation
• Implement high availability and redundancy solutions (stacking, failover, etc.)

• Perform system validation and commissioning of Wi‑Fi and LAN environments
• Execute acceptance testing, performance validation, and system verification
• Ensure solutions meet defined KPIs for performance, coverage, and reliability

• Troubleshoot wireless issues such as coverage gaps, interference, and roaming behavior
• Diagnose network problems including latency, packet loss, and configuration errors
• Use packet capture and RF analysis tools to isolate and resolve issues
• Optimize configurations for performance, stability, and scalability

• Execute network migrations and planned changes using defined procedures (MOPs)
• Support upgrades, cutovers, and system integrations
• Minimize service impact during transitions

• Produce and maintain:
  • As‑built documentation and network diagrams
  • Test plans and validation results
  • Issue logs and root cause analysis reports
• Provide daily progress updates and status reporting

• Act as a technical liaison with customers, internal engineering teams, and support organizations
• Support escalation and issue resolution processes
• Provide knowledge transfer and operational guidance to customer teams

• Strong knowledge of:
  • 802.11 Wi‑Fi standards and RF fundamentals
  • IP routing and switching concepts
  • VLANs, QoS, and network segmentation
• Experience with WLAN security (authentication, encryption, AAA/RADIUS)
• Familiarity with controller‑based and cloud‑managed wireless architectures

• Experience with switching technologies including:
  • VLANs, routing, STP/MSTP, VRF
  • High availability and redundancy design
• Understanding of structured cabling and data center environments

• Packet analysis tools (e.g., Wireshark or equivalent)
• RF survey and troubleshooting tools
• Network validation and performance testing tools

• 5-10+ years of experience in:
  • Wireless network deployment and troubleshooting
  • LAN or data center network engineering
• Proven experience with site surveys, implementation, commissioning, and optimization
• Relevant certifications preferred:
  • CWNA or equivalent wireless certification
  • Vendor certifications (Ruckus, Cisco, Aruba, etc.)
