We provide the financial infrastructure that powers the global economy. As a leading provider of market infrastructure and tradable products, Cboe delivers cutting-edge trading, clearing and investment solutions to market participants around the world. We’re building meaningful ways to support professional and personal development while strengthening the trust we’ve earned as a global market leader.
To support strong partnership and team connection, this role follows a four day in office work model.
The Network Operations Center (NOC) Engineer 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.
Your responsibilities will be:
- 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.
The ideal candidate has:
- 3+ 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.
- 2-3+ 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:
- Working knowledge of AWS cloud networking, including VPCs, routing, security groups, and hybrid connectivity models.
- Familiarity with 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.
