Network / Infrastructure Engineer - Low-Latency Trading

About the role

A recruiter representing several prop trading firms in Sydney is hiring experienced network and infrastructure engineers to design, build and run the low-latency infrastructure that trading depends on. The roles are hands-on and permanent, full time, with a flat, technical culture and no politics.

Key responsibilities

• Own the network and infrastructure end to end across co-location sites, exchange connectivity and each firm's internal environment.
• Handle switching and routing, multicast market data, cross-connects and circuits, servers and hardware, and the monitoring and automation that keeps things running.
• Work directly with traders, software engineers and SREs to design faster, more reliable infrastructure.
• Troubleshoot production problems when they occur; latency is measured in nanoseconds and downtime has a direct cost.

Required profile

• Several years of hands-on network or infrastructure engineering in production environments.
• Experience building and running real physical networks where latency and uptime mattered; cloud networking or enterprise IT experience alone is not enough.
• Rigorous, detail-oriented, with genuine ownership and urgency when it counts.
• Open to relocation to Sydney and visa sponsorship for suitable candidates, including Australian expats.

Required skills

• Strong networking fundamentals: routing, switching, multicast, VLANs and Ethernet.
• Strong Linux skills, including network configuration and performance tuning.
• Scripting and automation in Python or similar.
• Advantageous: low-latency networking such as Arista or similar switching, co-location, exchange connectivity, PTP/time synchronisation or packet capture.

What we offer

• Market-leading compensation as base salary plus bonus, all in cash, with no diluted equity.
• Unlimited technology budget for switches, NICs, timing gear and tooling.
• Flat structure with no layers of management.
• Full relocation and visa sponsorship available.
