The Role

You will be responsible for supporting, maintaining, and improving network infrastructure across production, disaster recovery, and test environments.

You will work closely with infrastructure, systems, security, engineering, operations, and customer-facing teams across multiple regions, helping ensure network stability, performance, resilience, and reliability across business-critical platforms.

Key Responsibilities

• Support and maintain low-latency network infrastructure across a global production environment.
• Troubleshoot complex network issues across routing, switching, firewalls, connectivity, latency, packet loss, TCP retransmissions, multicast, and performance.
• Work on network changes, upgrades, maintenance windows, and capacity planning.
• Support connectivity into exchanges, brokers, data centres, vendors, customers, and other market participants.
• Assist with customer connectivity onboarding, testing, certification, and troubleshooting.
• Use packet capture and analysis tools to investigate market data behaviour, packet loss, latency, multicast gaps, and connectivity issues.
• Partner with engineering and infrastructure teams on incident response, root cause analysis, service restoration, and long-term remediation.
• Contribute to network automation, monitoring, documentation, and operational process improvement.
• Support production environments that require strong ownership, attention to detail, and high levels of trust.

Experience Required

• Strong hands-on network engineering experience in a production environment.
• Good knowledge of routing, switching, TCP/IP, BGP, OSPF, multicast, VLANs, firewalls, and network security.
• Experience supporting high-availability, low-latency, or business-critical infrastructure.
• Background in financial services, trading, exchanges, market data, or capital markets technology would be highly advantageous.
• Experience with Cisco, Arista, Juniper, or similar enterprise network technologies.
• Strong troubleshooting skills and the ability to work calmly during production incidents.
• Experience with packet capture / packet analysis tools such as Corvil, Wireshark, tcpdump, or similar would be highly beneficial.
• Scripting, automation, monitoring, Python, APIs, UNIX shell, Grafana, or infrastructure tooling experience would be beneficial.
• AWS cloud networking experience would be advantageous.
• CCNP, CCIE, JNCIP, JNCIE, AWS, Network+, Security+, Corvil, or similar certifications would be viewed positively.
