Working across Linux, OpenStack, Kubernetes, and platform engineering, you will develop the tooling, automation, APIs, and services that enable infrastructure to operate reliably and at scale.\nThe successful candidate will have experience designing and evolving in-house custom-built infrastructure platforms at global scale, contributing to the architecture of large-scale OpenStack environments, and influencing platform design, engineering standards, and technical direction across globally distributed teams.\nWhat You'll Do\nDesign, build, and maintain internally developed platform services, APIs, automation frameworks, engineering tooling, and self-service platforms.\nDevelop software and platform capabilities primarily using Python, building scalable infrastructure services and distributed systems.\nDesign, develop, and evolve SIG’s global OpenStack and Kubernetes platforms, including platform services, integrations, operators, controllers, and automation frameworks.\nCreate and maintain CI/CD, GitOps, Infrastructure-as-Code, observability, and automation solutions supporting platform delivery and operations.\nTroubleshoot complex issues across Linux, OpenStack, Kubernetes, networking, storage, virtualization, and distributed systems.\nContribute to platform architecture, engineering standards, and technical direction through architecture reviews, design discussions, and technical governance initiatives.\nWhat we’re looking for\nStrong expertise in Linux engineering, including troubleshooting across kernel, networking, storage, virtualization, and complex production environments.\nProven experience in Python development and software engineering, building automation frameworks, APIs, platform services, engineering tooling, or infrastructure platforms used by other engineers.\nDeep Hands-on experience in OpenStack platform development and engineering, including contributing to platform architecture, engineering standards, and technical direction within large-scale or globally distributed environments.\nExtensive experience in Kubernetes platform engineering, including designing, building, operating, and extending production Kubernetes platforms through automation, operators, controllers, integrations, and platform services.\nStrong experience designing and operating large-scale distributed systems and custom-built infrastructure platforms within globally distributed engineering organisations.\nDesirable Experience\nExperience building internal developer platforms, shared infrastructure services, self-service systems, or engineering productivity tooling.\nExperience designing and operating large-scale distributed infrastructure, including multi-region architectures, hybrid cloud environments, or distributed storage platforms.\nContribution to open-source projects or experience leveraging AI-assisted development tools to accelerate platform engineering, automation, and software delivery.\nWhat We're Looking For\nStrong platform engineering and distributed systems mindset.\nExcellent troubleshooting, systems thinking, and problem-solving skills.\nAble to influence technical direction while
