Network Engineer

GemPool are now looking to hire a Network Engineer to join a highly skilled team responsible for designing, deploying, and operating large-scale IP and optical networks.

This is a 6-month contract position with extension opportunities.

You’ll work in an environment where scale, performance, and reliability are non-negotiable. This role combines deep hands-on engineering with design, planning, and troubleshooting across complex global networks.

Responsibilities:

• Design, rollout, and optimisation of large DWDM and optical transport networks
• IP network design and operation at scale, supporting backbone and data centre connectivity
• Optical planning, modelling, and capacity forecasting using industry-standard tools
• Ownership of network stability through advanced troubleshooting and root-cause analysis
• Working closely with global engineering teams to evolve network architectures and standards
• Contributing to automation, operational excellence, and continuous improvement initiatives

Experience Needed:

• 3+ years’ industry experience in large-scale network engineering
• Extensive hands-on experience with DWDM networks and optical transport technologies
• Strong background in optical planning and modelling tools
• Deep understanding of IP networking fundamentals and protocol behaviour at scale
• In-depth, practical experience with BGP and OSPF in complex environments
• Proven experience with major Cisco router platforms, including:
• 37xx, 49xx, 65xx, 73xx, 76xx
• Supervisory engines and line cards for these platforms
• Excellent network analysis and troubleshooting skills, including packet-level diagnostics

Preferred Technical Expertise:

• DWDM, T1/OTN
• IPv4 & IPv6
• TCP (internals, congestion & flow control)
• Routing & high availability: BGP, OSPF, HSRP, GLBP
• Multicast: PIMv2, IGMP
• MPLS & signalling: LDP
• Security & access: TACACS, IPSEC, VPNs
• Monitoring & visibility: NetFlow
• Core internet services: DNS, HTTP

Why Join?

• Work on an internet-scale infrastructure that few engineers ever get exposure to
• Solve complex problems that directly impact global services
• Collaborate with some of the most talented network engineers in the industry
• Opportunity to influence future network architectures rather than just operate them
• Strong focus on engineering excellence
• Opportunity for continuous learning
