Network Engineer

Overview

We are seeking a highly skilled Network Engineer to design, operate, and optimize a high-availability,

network infrastructure supporting mid-frequency trading operations. The role is critical to ensuring

resilient connectivity across internal networks, global exchanges, co-location facilities, and inter-office

links in a fast-paced, mission-critical environment.

The ideal candidate will have strong hands-on experience with enterprise and trading-grade

networking, L2/L3 troubleshooting, multicast market data distribution, and operational support in

production systems.

Key Responsibilities

Network Design & Operations

• Design, manage, and optimize high-availability network infrastructure, including routers,
  
  

switches, firewalls, load balancers, VPNs, and QoS policies for trading and corporate

environments.

• Ensure reliable, low-latency connectivity between internal systems, global exchanges, colocation sites, and inter-office networks.
• Configure and maintain multicast routing (PIM, IGMP) for market data distribution and order
  
  

execution systems.

Trading & Co-Location Support

• Manage connectivity with domestic and international exchanges across multiple regions.
• Oversee co-location site operations, including power, space, rack capacity planning, access
  
  

management, vendor coordination, and procurement.

• Act as a technical point of contact for telecom providers, data center operators, and hardware
  
  

vendors.

Monitoring, Troubleshooting & Support

• Provide L2/L3 production support in a live trading environment.
• Monitor network performance and availability; proactively identify and resolve issues.
• Troubleshoot complex network problems using tools such as Wireshark, Tcpdump, Iperf, and
  
  

SNMP-based monitoring systems.

• Participate in incident response, root cause analysis, and post-incident reviews.
  
  

Automation & Continuous Improvement

• Automate network configuration, deployment, and monitoring tasks using Python and/or Shell
  
  

scripting.

• Perform firmware upgrades, configuration changes, and capacity planning with minimal
  
  

downtime.

• Drive continuous improvements in network reliability, performance, and scalability.
  
  

Systems & Collaboration

• Provide basic support for Linux-based trading systems (Ubuntu/CentOS), including hardware
  
  

changes, OS-level configuration, and application support as required.

• Maintain accurate documentation for network architecture, configurations, procedures, and
  
  

incident logs.

• Collaborate closely with trading desks, quant teams, system administrators, and external
  
  

vendors.

• Travel occasionally to co-location or data center sites as business needs require.
  
  

• Bachelor’s degree in Computer Science, Electrical Engineering, Computer Engineering, or a
  
  

related IT discipline.

• 3–5 years of hands-on experience in network engineering or network support roles.
• Strong understanding of TCP/IP, routing, switching, VLANs, BGP, OSPF, and network security
  
  

fundamentals.

• Experience working in high-availability or mission-critical environments; exposure to trading
  
  

or financial services is highly desirable.

Preferred Skills & Experience

• Hands-on experience with Cisco and/or Arista routers and switches.
• Experience managing firewalls, VPNs, and network security policies.
• Strong knowledge of multicast networking (PIM, RP, MSDP, IGMP).
• Good to have CCNA / CCNP (Routing & Switching) certification or equivalent practical
  
  

knowledge.

• Proficiency with Linux systems (Ubuntu, CentOS/RHEL).
• Experience with network automation using Python or Shell scripting.
• Familiarity with performance and diagnostic tools such as Wireshark, Tcpdump, Iperf.
• Ability to work under pressure in time-sensitive environments with strong problem-solving and
  
  

decision-making skills.

• Clear communication skills and the ability to collaborate effectively across technical and nontechnical teams.
  
  

Why Join Us

• Work in a cutting-edge trading environment where network performance directly impacts
  
  

business outcomes.

• Exposure to exchange connectivity, market data systems, and co-location infrastructure.
• Opportunity to take ownership of critical infrastructure and contribute to performance-driven
  
  

engineering decisions.
