Network Engineer (Trading Infrastructure)

---

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
