Senior Network Engineer

Senior Network Engineer | Kanji IT

Own the Network. Master Linux. Solve the Hard Problems.

Kanji IT is looking for a Senior Network Engineer to take ownership of enterprise network operations, infrastructure, and L3 escalation across a complex APAC environment.

Based in Sydney CBD, this is a hands-on senior role for an engineer who is equally comfortable troubleshooting BGP and OSPF, managing enterprise networks, diving deep into Linux, analysing packet captures, and solving complex infrastructure issues.

You’ll be part of a follow-the-sun technical team across Sydney, Auckland, and Perth, working closely with infrastructure, security, development, and support teams.

About the Role

You’ll be a key technical escalation point responsible for keeping Kanji IT’s LAN, WAN, WLAN, and data centre networks reliable, secure, and highly available.

This role combines advanced network engineering with strong Linux administration and engineering. You’ll have genuine ownership of the environment and the opportunity to improve network design, performance, monitoring, automation, and operational processes.

Strong Linux experience is essential. We’re looking for someone with proven experience as a Linux Administrator, Linux Engineer, or senior infrastructure professional who can troubleshoot complex networking issues directly from within Linux environments.

Key Responsibilities

• Act as the L3 escalation point for complex network incidents and problems
• Operate, troubleshoot, and optimise enterprise LAN, WAN, WLAN, and data centre networks
• Design, peer-review, implement, and validate network changes
• Troubleshoot BGP, OSPF, VLANs, STP, LACP, MLAG/VPC, QoS, and policy-based routing
• Perform packet captures, traffic analysis, and root-cause investigations
• Manage enterprise WiFi infrastructure, including Extreme Networks controllers
• Troubleshoot 802.1X, RADIUS, WPA2/WPA3, roaming, and guest networks
• Administer and troubleshoot Linux environments across CentOS and Ubuntu
• Troubleshoot Linux networking using iproute2, nftables/iptables, tc, namespaces, bonding, bridging, VLANs, and policy routing
• Manage enterprise firewalls, VPNs, and Linux-based firewalling
• Support network monitoring, logging, and observability platforms
• Develop automation and tooling using Bash and Python or Go
• Maintain accurate network architecture and operational documentation
• Identify opportunities to improve reliability, automation, performance, and support processes

About You

You’re a senior engineer who enjoys getting into the detail, solving complex problems, and taking ownership.

You’ll bring:

• 5+ years’ experience in network engineering, including at least 2 years at senior/L3 level
• Strong production experience with BGP and OSPF
• Advanced Layer 1, Layer 2, and Layer 3 troubleshooting skills
• Proven professional experience as a Linux Administrator, Linux Engineer, or senior Linux-focused Infrastructure Engineer
• Strong hands-on Linux administration experience across CentOS and/or Ubuntu
• Ability to diagnose and troubleshoot network issues directly from a Linux host without relying on GUI tools
• Strong understanding of the Linux networking stack, including iproute2, nftables/iptables, tc, namespaces, bonding, bridging, VLANs, and policy routing
• Experience managing enterprise wireless environments
• Strong understanding of TCP/IP and network fundamentals
• Experience with enterprise firewalls and VPNs
• Strong problem-solving and analytical skills
• Excellent documentation and incident communication skills
• Experience with Bash and at least one scripting language such as Python or Go
• Ability to work independently while collaborating effectively with technical teams

Nice to Have

• Ansible or other network automation experience
• Experience with Nagios, Prometheus, Grafana, ELK, Splunk, Datadog, or similar monitoring platforms
• CCNP, CCIE, RHCE, or relevant industry certifications
• Degree in Computer Science, Engineering, or a related discipline
