Job description

The Cboe office in London is situated in The Monument Building, a modern space that spans two floors and features a spacious outdoor balcony. From the balcony, employees can enjoy stunning views of some of London's most iconic architectural landmarks, adding a unique touch to the work environment. The building is equipped with convenient amenities for office commuters, including bike storage and showers, making it easy for staff to freshen up after their commute. Its prime location in the heart of London's financial district ensures that employees have easy access to a variety of cafes, restaurants, and shops, creating an ideal balance of work and leisure., 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. NOC Engineers function as true engineers-owning complex troubleshooting, real-time monitoring, incident response, change execution, and customer connectivity onboarding-while operating independently with minimal supervision. They collaborate directly with internal engineering teams and external customers, serve as escalation points, and communicate clearly with both technical stakeholders and senior leadership, translating complex issues into actionable outcomes. The role also emphasizes building efficient, modern operations through scripting, automation, and API-driven workflows to improve observability, accelerate root cause analysis, and reduce mean time to repair (MTTR). While familiarity with AI-assisted tooling is beneficial, the primary focus is on strong engineering fundamentals and practical automation that reduces operational friction. Success in this role requires sound operational judgment, strong communication skills, and the ability to translate complex telemetry and packet-level data into clear, actionable insights. Engineers are expected to perform effectively in a high-availability, always-on environment while supporting and evolving a next-generation, software-driven network and cloud operations function. 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
  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
