Senior Network Engineer — Low Latency Trading Infrastructure

Locations: Chicago • New York • London • Seattle • Singapore

Let’s get Straight to it.

We’re partnered with a Premier Algorithmic Trading organization operating at Global Scale —

engineering the Ultra-High-Performance Networks that Power Real-time Trading and Research Platforms across more than 25 countries and 100+ locations.

These environments don’t tolerate Latency, instability, or guesswork — they demand precision, depth, and ownership.

We’re looking for a Senior Network Engineer who thrives where performance matters and complexity is real.

This role sits at the intersection of Architecture, Engineering, and operations —

working alongside Elite systems and Trading teams to design, deploy, and continuously refine the global communications backbone supporting latency-sensitive workloads.

You’ll influence technology selection, routing strategy, troubleshooting, and long-term network direction — with direct impact on production outcomes.
It’s a build-and-solve environment for engineers who want their work to matter.

What You’ll Work On

• Designing and Operating Large-Scale, High-Capacity Global Network Environments
• Routing Strategy and Troubleshooting across L2/L3 protocols (BGP, OSPF, PIM, IGMP)
• Managing High-Performance Switching platforms (Arista, Cisco)
• Supporting Multicast Market Data distribution and WAN connectivity
• Packet-level diagnostics using tcpdump, Wireshark, and related tools
• Collaborating with Trading and Infrastructure teams to Optimize Performance
• Capacity planning and lifecycle network project delivery
• Evaluating fiber, optics, and connectivity solutions
• Automation and observability tooling integration (Ansible, Python, Prometheus, etc.)

What You Bring

• 5–10+ years designing and operating complex network environments
• Strong foundation in low-latency or performance-sensitive systems (trading experience a plus)
• Deep understanding of routing protocols and network architecture
• Experience with Linux/Unix networking stack
• Hands-on troubleshooting mindset — comfortable solving issues directly
• Ability to communicate clearly and document technical decisions
• Exposure to microwave/optical transport, cloud networking, or network automation is valuable
