Job description

Are you a Senior Network Engineer who wants genuine ownership of the network environment rather than simply maintaining someone else’s infrastructure?

We’re working with a rapidly growing data center and mission-critical infrastructure business that is building out a highly connected technology environment across corporate offices, data center sites, and active construction locations.

We're looking for a Senior Network Engineer to take a leading technical role in designing, securing, implementing and operating this network infrastructure.

The Opportunity

This is a highly hands-on senior engineering position where you’ll have the opportunity to influence architecture, standards and security while working across an environment that is evolving rapidly from greenfield construction through to live data center operations.

You’ll work closely with the Director of IT Infrastructure and become the senior technical escalation point for complex network and connectivity issues.

One day you could be architecting a new site network; another could involve troubleshooting BGP, hardening firewall policies or leading root-cause analysis following a major network incident.

RESPONSIBILITIES:

• Design and implement enterprise networks across data centers, corporate offices and construction sites
• Work extensively with Palo Alto firewalls and Cisco switching
• Architect routed and switched environments using TCP/IP, BGP, OSPF, VLANs and LAN/WAN technologies
• Design and administer Microsoft Azure networking, including VNets, ExpressRoute, VPN gateways and hybrid connectivity
• Develop network standards, IP addressing schemes, reference architectures and documentation
• Implement network security, segmentation, VPN, access controls and intrusion prevention
• Support vulnerability assessments and penetration testing activities
• Diagnose complex network issues and lead root-cause analysis
• Monitor network performance, capacity and reliability
• Lead network projects from requirements and design through implementation, testing and handover
• Coordinate with vendors, carriers, construction and operations teams
• Help deliver connectivity from temporary construction facilities through to permanent infrastructure
• Mentor junior engineers and contribute to technical standards, runbooks and best practices

REQUIREMENTS:

• 6–10+ years' enterprise network engineering experience
• Strong hands‑on experience with Palo Alto and Cisco
• Deep knowledge of BGP, OSPF, TCP/IP, VLANs and LAN/WAN design
• Experience with Azure networking and hybrid cloud environments
• Strong understanding of network security and vulnerability management
• Proven experience troubleshooting complex network environments
• Experience leading network projects and formal change management
• Knowledge of wireless broadband / remote-site connectivity
• Excellent communication skills and the ability to explain technical concepts to non-technical stakeholders

Highly Desirable

Experience within data centers, construction or other mission-critical environments would be a major advantage.

We're also interested in engineers with experience across:

Why Consider It?

This isn't a role where you'll simply inherit an established network and keep the lights on.

You'll be joining an organization in a significant growth phase, helping build the infrastructure that supports major data center developments and having genuine input into how the network architecture evolves.
