Senior Low Latency Engineer - Vice President

We are seeking a Senior Low Latency Engineer to deploy, build, and operate ultra-low latency network infrastructure supporting high-frequency trading (HFT) and market data platforms. The role requires deep expertise in multicast market data distribution, TCP/IP stack behavior, packet-level analysis, and observability (Corvil/cPacket), along with strong experience in Cisco/Arista platforms integrated environments.

In the Technology division, we leverage innovation to build the connections and capabilities that power our Firm, enabling our clients and colleagues to redefine markets and shape the future of our communities. This is a Infrastructure Production Management & Reliability Engineering position at the Vice President level, which is part of the job family responsible for maintaining the stability and reliability of the organization's infrastructure systems, ensuring optimal performance and availability to support business operations.

What you''ll do in the role:

• Market Data Connectivity & Trading Network Engineering

  • Actively participate in design/engineering decision, deploy and support low-latency market data infrastructure (multicast, exchange connectivity)

  • Optimize high-speed data delivery pipelines and ensure deterministic performance for trading systems

  • Engineer robust resilient architectures for real-time data distribution and failover

• Routing & Network Protocols

  • Design, implement, and troubleshoot routing protocols (BGP, OSPF, RIP)

  • Optimize routing for low-latency, high-throughput trading environments

  • Manage route convergence, failover, and traffic engineering strategies

• Multicast & Network Protocol Expertise

  • Manage and troubleshoot UDP multicast (PIM, IGMP), TCP/IP stack, and feed handler connectivity

  • 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:

• Cisco & Arista switching/routing platforms

• Data center and co-location network architectures

• FPGA-based systems or hardware-accelerated networking

• Ultra-low latency trading environments (HFT, market making, exchanges)

• Programming / scripting knowledge (Python preferred) for automation

• Strong understanding of FIX, market data protocols, and real-time systems architecture [community.cisco.com]
