The Senior Linux Platform Operations Engineer is a hands-on infrastructure specialist who designs, builds, and maintains the server, storage, operating system, and configuration layers that support all trading environments. This role sits within a small, highly skilled team of engineers focused on reliability, performance, and automation. Members of this team work hands-on with modern hardware, develop in-house automation and monitoring solutions, leverage open-source technologies, and make meaningful contributions to systems that are critical to the business.

The Senior Linux Platform Operations Engineer must be able to work independently with limited direct supervision, demonstrating ownership over assigned infrastructure domains including bare-metal systems, OS lifecycle, configuration management, and tooling. This role collaborates closely with other Infrastructure, Software Engineering, SRE, and Security teams globally, and serves as a technical escalation point for Linux-related incidents and capacity questions.

1. Systems Build & Configuration Management: Design, build, and maintain server and storage infrastructure supporting all global trading environments. Provide configuration management of new and existing Linux platforms using Salt. Build and manage RPM packages and deploy system updates globally. Monitor engineering activities and change management tickets, evaluating their impact on production operations. Execute change tickets in support of updates to production, disaster recovery, and certification systems. While the primary focus is bare-metal on-premises infrastructure, experience with cloud platforms (AWS, GCP) and containerization (Docker, Kubernetes) is desirable as Cboe evolves its infrastructure strategy.

2. Incident Response & Technical Troubleshooting: Serve as a primary technical responder for P1/P2 Linux infrastructure incidents. Lead or participate in incident triage, root cause analysis, and resolution in coordination with globally distributed engineering and operations teams. Author post-incident reviews and drive remediation tracking to improve long-term platform stability. Provide clear, timely communication to stakeholders during active incidents.

3. Performance Tuning & System Availability: Work closely with Linux Platform Engineering, development and SRE teams on capacity scaling and performance tuning. Deep understanding of the Linux Kernel (scheduling, networking, I/O, monitoring). Operate and maintain low-latency bare-metal infrastructure including hardware health, kernel-bypass networking stacks (e.g., Solarflare/Onload), and NIC configuration. Ensure the operational resiliency of all systems globally.

4. Automation & Process Improvement: Maintain an automate everything attitude - actively identify and reduce administrative overhead through automation. Develop, test, and deploy automation solutions using Python and Shell scripting. Provide thought leadership to identify opportunities for automated system health monitors, alerts, and self-remediating workflows. Leverage AI tools to maximize team efficiency. IaC tooling such as Terraform experience is desired.

5. Reporting & Observability: Create and improve operational reports related to Linux platform health, patch compliance, capacity utilization, and incident metrics (MTTR, patch %, backup success rates). Build and maintain dashboards using Grafana, Prometheus, or equivalent tooling. Analyze system telemetry data sets to troubleshoot or explain perceived performance issues.

6. Infrastructure Project Ownership: Represent the Linux Platform Operations team and take ownership of the team portion of large infrastructure projects. Gather, organize, document, and clearly communicate project requirements to relevant teams. Work across Engineering, Network, and Security teams to execute platform initiatives end-to-end.

7. On-Call & Weekend Testing: Participate in on-call rotations to support production Linux infrastructure 24x7. Lead or participate in weekend maintenance windows, failover tests, and capacity testing exercises as part of Cboe global operations team.
