Descrizione del lavoro

Linux Systems Engineer (Bare Metal & Kubernetes)

Cox Purtell About the Role As Linux Systems Engineer, you'll join the Global Linux team responsible for the infrastructure that powers a live trading environment, spanning large-scale bare-metal Linux platforms and on-prem Kubernetes clusters. You'll design, build and operate systems the business depends on every day, from hardware provisioning through to orchestration and automation. This is ownership of foundational infrastructure, not managed cloud abstraction, in a setting where reliability and performance matter.

Duties

• Design, deploy and operate on-prem Kubernetes clusters in a bare-metal environment.
• Maintain and improve bare-metal Linux infrastructure, including provisioning, lifecycle management and performance tuning.
• Own and operate core Kubernetes components such as the CNI, GitOps tooling and cluster management layer (currently Cilium, ArgoCD and Rancher).
• Build and maintain CI/CD workflows and infrastructure as code for infrastructure and cluster deployments.
• Take part in an on-call rotation, drive post-incident improvements, and document runbooks so the wider team can support the platforms.

Requirements

• Strong Linux systems engineering experience in a production environment.
• Hands-on experience running Kubernetes or comparable infrastructure on-prem, not solely through managed cloud offerings.
• Experience with infrastructure as code and CI/CD or GitOps workflows. Terraform, ArgoCD, Rancher, Cilium and GitHub Actions are all useful, and depth in the specific stack can be built on the job.
• Solid understanding of networking fundamentals, including L2/L3, routing, firewalls and load balancing.
• Experience troubleshooting performance issues across the kernel, container and network layers.
• A production mindset, with experience in incident response and post-mortem-driven improvement.
• Experience with Prometheus, Grafana, Kubernetes security controls, or low-latency and high-performance environments will be highly regarded.

If this sounds like the kind of infrastructure challenge you're after, we'd love to hear from you. Salary benefits: (Package incl Bonuses & Super) Work Type: Full time Salary: $200000-300000 Job Publish: 03-11-2026 Job Expire: 03-12-2026
