• Direct line of sight to trading outcomes: your work has a measurable, visible impact on performance
• Genuine investment in technical development, with scope to work across several new projects starting early in 2027
• A team culture built around technical excellence rather than hierarchy

• Monitor and troubleshoot the network environment as part of a global team
• Design and implement network and security solutions
• Analyse and resolve network performance issues
• Provide expert-level fault resolution on advanced HFT network connectivity
• Work closely with development, data centre, and project teams

Experience required for Network Engineer:

• CCNA/CCNP certified
• Financial services background required
• Solid knowledge of OSPF, BGP, EIGRP, and IPSEC
• Experience with client-server architecture and network support
• Scripting experience is a plus
• Experience securing network infrastructure, including firewalls, network segmentation, and access control
• Intrusion detection/prevention systems (IDS/IPS) and network monitoring for security threats
• Understanding of security best practice within a regulated financial environment

Package: Superb bonus, private medical insurance, contributory pension, free gym membership, 28 days holiday.
