Senior Network Engineer | Global Trading Infrastructure

Permanent or Contract

Work on high-performance networks where reliability, security and latency directly influence trading outcomes.

Firesoft People is partnering with a global trading firm to recruit a Senior Network Engineer for its IT Operations team. This opportunity suits an experienced engineer with deep networking expertise who enjoys owning design decisions, solving complex problems and improving mission-critical infrastructure.

The opportunity

You’ll support and enhance infrastructure spanning global exchanges, colocation facilities and on-premises environments. The technology includes enterprise bare-metal hardware, FPGA-accelerated components and low-latency network architectures.

Working alongside a collaborative engineering team, you’ll own meaningful projects, contribute to architecture decisions and help deliver major infrastructure upgrades.

What you’ll do

• Maintain and improve highly available core and WAN networks, including routing, switching, multicast and exchange connectivity.
• Design, troubleshoot and optimise environments using BGP, OSPF, PIM and IGMP.
• Own firewall policies and investigate complex network issues through packet captures and detailed analysis.
• Support and tune Red Hat Enterprise Linux systems across bare-metal hardware and hypervisors.
• Design and implement security controls and disaster recovery procedures.
• Lead maintenance windows and infrastructure upgrades, coordinating with internal teams, exchanges and colocation providers.
• Improve configuration management, monitoring and operational tooling using Ansible, Zabbix and Python.
• Respond to incidents, identify root causes and implement improvements that strengthen resilience and performance.

What you’ll bring

• Typically five or more years of experience supporting complex, mission-critical infrastructure.
• Strong core and WAN network design expertise, with the ability to explain and justify your architectural decisions.
• Deep hands-on knowledge of BGP, OSPF, firewall policies and packet-level troubleshooting.
• Experience with multicast networking, including PIM and IGMP.
• Hands-on experience across colocation and on-premises switching and connectivity.
• Strong Linux skills, ideally with RHEL in high-performance environments.
• Experience with infrastructure automation, configuration management and monitoring tools.
• A proactive approach to identifying risks and opportunities for improvement.
• Clear communication, sound judgement and the ability to remain composed during time-sensitive incidents.

Why consider this role?

• Work on technically demanding, low-latency trading infrastructure.
• Take ownership of projects and influence network and infrastructure design.
• Join a collaborative team that values practical engineering and well-designed solutions.
• Explore either a permanent or contract engagement.
