- Ensure efficient bandwidth utilization and low jitter/latency in high-throughput environments
- Observability & Packet Analysis
- Perform deep packet capture (pcap) analysis to investigate latency, packet loss, and feed gaps
- Leverage Corvil/cPacket and similar tools to provide real-time visibility into trading and network performance
- Conduct root cause analysis for production incidents impacting market data/trading systems
- Low Latency Infrastructure & FPGA Integration
- Work with FPGA-based network acceleration platforms used for ultra-low latency trading systems
- Integrate FPGA, NIC offloads, and hardware optimizations into network architecture
- Ensure alignment between hardware, network, and trading applications for microsecond performance
- Network Architecture & Engineering
- Design and maintain high-performance networks using Cisco and Arista platforms
- Optimize switching, routing, and L2/L3 design for co-location and exchange environments
- Implement best practices for high availability, scalability, and deterministic latency
- Troubleshooting & Incident Management
- Lead troubleshooting of critical production issues in trading environments
- Perform real-time diagnostics across network, application, and infrastructure layers
- Collaborate with trading, Dev, and infrastructure teams for rapid resolution
- Automation & Continuous Improvement
- Drive automation (Python/Ansible) for network provisioning, monitoring, and validation
- Improve observability frameworks and latency monitoring pipelines Required Skills & Experience
What you'll bring to the role:Deep expertise in:
- Market Data connectivity (exchange feeds, multicast, feed handlers)
- Multicast (PIM, IGMP), TCP/IP internals, low-latency networking
- Packet capture tools (tcpdump, Wireshark) and traffic analysis
- Corvil / cPacket or similar observability platforms
Strong hands-on experience with:
