Our client, a leading London-based connectivity and technology organisation, is hiring a 3rd Line Network Engineer to provide senior-level technical support across business-critical customer networks.

Sitting at the top technical tier of the support function, you'll take ownership of complex network faults requiring deeper expertise across routing, switching, wireless and customer-facing network infrastructure. You'll own escalated incidents through to resolution, make configuration changes on live network equipment and investigate recurring problems to identify and implement permanent fixes.

Beyond resolving individual incidents, you'll help improve the wider support operation, developing technical playbooks, improving monitoring and giving 1st and 2nd Line teams the knowledge they need to resolve more issues without escalation.

What you'll do:

  • Own complex and escalated network faults through to full resolution
  • Troubleshoot issues across routing, switching, wireless and customer network infrastructure
  • Make and document configuration changes on live customer-facing network equipment under change control
  • Work with customers, field engineers, suppliers and internal network teams to diagnose and resolve incidents
  • Troubleshoot wireless issues remotely, supporting engineers on-site with surveys, access point placement, cabling and power checks
  • Develop deep technical knowledge across the organisation's wireless networking platforms
  • Escalate core network issues to Network Operations with the diagnosis and customer impact already established
  • Monitor network events with the potential to impact multiple customers and correlate these against incoming incidents
  • Lead problem management for recurring faults, identifying root causes and driving permanent fixes
  • Produce clear Root Cause Analysis (RCA) and Reason for Outage documentation for customer-facing incidents
  • Develop technical playbooks and documentation to improve resolution rates across 1st and 2nd Line Support
  • Improve network monitoring and alerting processes
