Network Engineer (Trading Infrastructure)

About this role

We’re looking for a Network Engineer to join our Trading Infrastructure team. You will work on end-to-end network tasks: from new site and provider connectivity to validation, troubleshooting, and performance bottleneck analysis. The role is focused on low-latency and performance-sensitive environments and involves close collaboration with vendors, carriers, systems and hardware engineers.

What You’ll be doing

• Design, build, and operate network connectivity for trading infrastructure across colocation sites and regions

• Deliver end-to-end network setups: cross-connects, routing, validation testing, and go-live readiness

• Investigate and resolve complex network issues affecting latency, jitter, packet loss, or reliability

• Identify and address bottlenecks across the stack together with systems and hardware engineers

• Support timing-sensitive networking (PTP/NTP): bring-up, validation, monitoring, and troubleshooting

• Work on connectivity to cloud providers

• Improve repeatability through automation, templates, and tooling

• Contribute to operational readiness: runbooks, checklists, incident reviews (RCA), inventory and documentation

• Participate in scheduled on-call rotations to support network operations and incident response

What we look for in you:

• Hands-on experience operating and troubleshooting production networks, Linux and NGFW

• Solid understanding of routing and switching fundamentals (BGP, OSPF, VLANs, L2/L3 design)

• Good understanding of how networks impact system and application performance

• Ability to work end-to-end and collaborate across domains (systems, hardware, vendors)

• Automation mindset; scripting experience (Python/Bash) is a plus

• Passion for technology and continuous learning

Nice-to-Have:

• Experience in low-latency or performance-sensitive environments (trading, exchanges, market data)

• Colocation and provider connectivity experience (cross-connects, optics, acceptance testing)

• Experience with cloud connectivity (Direct Connect, ExpressRoute, Cloud Interconnect, etc.)

• PTP/NTP experience and understanding of timing-related failure modes

• CCNP-level (CCNP SP / CCNP DC / CCNP Ent knowledge or equivalent hands-on experience

Why should you join our team?

• Exciting challenges with ample opportunities for personal and professional growth

• A welcoming international team of highly qualified professionals

• Cutting-edge hardware and technology
