Linux System Engineer

Linux & Trading Infrastructure Engineers – Multiple Roles | Sydney We’re currently hiring across multiple infrastructure engineering positions with leading quantitative trading firms in Sydney. These opportunities suit hands-on engineers who enjoy working close to Linux, physical infrastructure, networking and production systems. While the exact focus differs across each team, all three roles operate in highly technical, performance-sensitive environments where reliability and infrastructure quality are critical. The Opportunities Linux Systems Engineer – Bare Metal & Kubernetes Work across large-scale bare-metal Linux infrastructure and on-prem Kubernetes environments. You’ll help design, operate and improve production platforms, with technologies including Rancher, Cilium, ArgoCD, Terraform and GitHub Actions. Linux Production Engineer Build, administer and support high-performance Linux infrastructure used across trading and research. The role combines day-to-day production engineering with server deployments, upgrades, automation, monitoring and platform improvements. Trading Infrastructure Engineer Work directly with the physical infrastructure underpinning latency-sensitive trading systems. You’ll cover Linux server deployment, OS and hardware optimisation, networking, automation, monitoring and production troubleshooting. What We’re Looking For Across the three positions, we’re interested in engineers with experience across: Strong Linux systems engineering / administrationBare-metal or physical server infrastructurePython and/or Bash scripting and automationNetworking fundamentals and troubleshootingProduction infrastructure and incident responseInfrastructure automation and configuration managementMonitoring, observability and performance troubleshooting Depending on the role, experience with Kubernetes, Rancher, Cilium, ArgoCD, Terraform, Ansible, multicast networking, PTP, colocation or low-latency infrastructure will be particularly valuable. Why Consider These Roles? These are opportunities to move into or continue building a career within quantitative trading while remaining deeply hands-on technically. Prior trading experience is not essential across all of the opportunities; strong engineers from high-performance infrastructure and production environments are encouraged to apply. If you’re a strong Linux/infrastructure engineer and would like to understand which of the three teams best aligns with your background, apply or get in touch for a confidential discussion.
