Network Engineer - Operations

Role Overview

The Network Engineer - Operations, is a core member of Cboe’s global infrastructure organization, responsible for operating, supporting, and continuously improving the reliability, performance, and fairness of network connectivity across highly distributed, latency-sensitive trading platforms spanning on-prem and cloud environments.

This is a hands-on engineering role for experienced network technologists with deep expertise in routing, MPLS, firewalls, and packet-level troubleshooting, combined with working knowledge of cloud networking and automation.

Responsibilities

• Engineer and support customer connectivity across on-prem and cloud environments, including circuit provisioning, AWS networking, and VPN connectivity, while configuring and deploying production changes across routing, firewall, and cloud network infrastructure
• Troubleshoot and support complex network environments (BGP, OSPF, MPLS, multicast, HSRP), partnering with customers and internal teams to validate connectivity, onboard new participants, and resolve issues across latency-sensitive trading systems
• Provide real-time monitoring and incident response for global network infrastructure, analyzing telemetry, packet loss, and performance data to proactively identify issues and drive rapid resolution with clear communication
• Deliver high-quality customer support through ticket queues and direct engagement, serving as a trusted technical resource and ensuring clear, timely communication with both customers and internal stakeholders
• Lead escalations and advanced troubleshooting efforts across network, cloud, and infrastructure domains, collaborating with engineering teams and vendors to restore service and resolve complex issues
• Develop and maintain automation, monitoring enhancements, and observability tooling using scripting and API-driven integrations to improve efficiency, visibility, and troubleshooting speed
• Perform deep packet analysis and contribute to root cause investigations, translating low-level network data into clear findings that support long-term problem management and service improvement

Minimum Qualifications

• 2+ years of hands-on network engineering experience across Cisco, Arista, and/or Palo Alto environments, with strong fundamentals in routing, switching, and firewall technologies
• Experience troubleshooting complex network issues, including packet analysis using tools such as tcpdump, Wireshark, tshark, or similar
• 2+ years of UNIX/Linux experience, including shell access and command-line troubleshooting, with an emphasis on network diagnostics
• Experience with scripting and/or API-driven automation to improve operational efficiency and reduce manual effort

Preferred Qualifications

• Familiarity with AWS cloud networking, including VPCs, routing, security groups, and hybrid connectivity models
• Working knowledge of network observability and monitoring tools (e.g., Grafana or similar) for telemetry analysis and troubleshooting
• Experience with advanced packet capture platforms (e.g., Corvil) or equivalent high-performance analysis tools
• Relevant industry certifications such as Cisco, AWS, Palo Alto, CompTIA Network+/Security+, or similar
