We are looking for a Network Analyst who can provide support as our team builds automation and DevOps-driven solutions – encouraging creativity in leveraging AI wherever possible.

Our global network infrastructure underpins a variety of traffic profiles, from fast-paced trading to broader internet connectivity. You’ll partner with our senior engineers and developers across the firm to enhance existing workflows, streamline processes and ensure that our network remains stable, secure and adaptable.

Working with project managers on site expansions, new market data feeds and connections to third-party services
Maintaining and improving our monitoring and alert systems, with a strong emphasis on automation, AI integration and DevOps practices
Using scripting or development tools to reduce manual tasks, enhance network visibility and explore innovative AI-driven solutions

This position is an exciting chance to be directly mentored by experienced network engineers with cutting-edge hardware, protocols and DevOps tools. Your daily support will have a direct impact on our operational excellence and your contributions to automation, AI integration and tooling will define the future of our network.

About You

Experienced with operating and troubleshooting LAN/WAN networks
Familiar with common routing and switching protocols (e.g., OSPF, BGP, PIM-SM)
Able to debug transport protocols (TCP/UDP)
Comfortable in Linux environments and have some programming or scripting knowledge
Enthusiastic about automation (for instance, using Python or similar tools) to simplify network operations, and open to AI-powered optimisations
Eager to learn and adapt, creative and open to feedback
Strong communicator; ready to interface with global teams and internal stakeholders
Organised and flexible, able to balance day-to-day support with longer-term projects
Have a collaborative spirit and thrive in a hands-on, team-driven environment
