HFT Network Engineer

At Gravity Team, a quantitative proprietary trading firm, we are on a mission to balance the supply and demand across crypto markets worldwide.

Join our community of innovators, problem solvers, and owners who apply scientific discovery techniques to make crypto markets a better place for everyone.

You are

A low latency network engineer. You understand that in trading microseconds matter, and you know how to find and eliminate them. You’re pragmatic, systematic and capable of working independently across complex systems spanning dozens of global trading venues.

You enjoy working at the intersection of networking, infrastructure and trading. You know how to navigate incomplete information, changing requirements and global constraints.

What you will do

• Design, deploy, and maintain ultra-low-latency network infrastructure connecting several dozen trading venues.
• Measure and analyze end-to-end latency, packet loss, and jitter; identify and eliminate bottlenecks.
• Build optimized routing paths, BGP configurations, and peering strategies for global trading connectivity.
• Work with data center and telecom providers to establish cross-connects, leased lines, and dark fiber routes.
• Tune Linux networking stacks and NIC configurations for microsecond-level performance.
• Automate network monitoring, telemetry, and alerting systems.
• Collaborate with devops, trading and infrastructure teams on seamless networking solution integration in trading algorithms.
• Maintain network security and resilience while optimizing for minimal overhead.
  
  

What we expect

Must-have

• 3+ years in a similar Network Engineer / Infrastructure / SRE role focused on performance and reliability.
• Proven experience designing and operating low-latency, high-throughput networks.
• Strong theoretical and practical knowledge of TCP/IP, routing (especially BGP), and network diagnostics.
• Hands-on experience with Linux network tuning, kernel parameters, and packet capture/analysis tools (e.g., tcpdump, Wireshark, Corvil).
• Experience with data center networking, colocation connectivity and cross-connect provisioning.
• Demonstrated success in reducing latency or jitter across distributed systems.
• Ability to automate network configuration and monitoring (Python, Ansible, or equivalent).
• Security-first mindset - experience balancing low latency with robust protection (DDoS mitigation, ACLs, etc.).
  
  

Nice-to-have

• You bring insights or optimizations we haven’t discovered yet - unique approaches that make networks faster, leaner, or more reliable.
• Networking design experience for crypto or trad-fi HFT systems.
• Experience with BGP peering and optimization, route-maps, and latency-based routing policies.
• Exposure to exchange connectivity protocols (FIX, WebSocket, proprietary APIs).
• Familiarity with FPGA acceleration, kernel bypass frameworks (DPDK, VMA), or hardware timestamping.
• Understanding of crypto exchange infrastructure, colocation ecosystems and market data networks.
• Willingness to support mission-critical trading infrastructure outside working hours.
