Linux / Kubernetes Engineer

Explore your Kubernetes path with us. Please note: We are not able to consider candidates who are not living and working in the Netherlands. At this moment we are not providing relocation sponsorships. At Schuberg Philis, we specialize in mission-critical IT. We work side-by-side with our customers to ensure their most critical digital services remain reliable, secure, and continuously available. Our engineers are T-shaped professionals: people with deep expertise, broad technical understanding, and a strong sense of ownership. Within our dedicated, multidisciplinary, and self-managing customer teams, we take responsibility for complex technology environments and long-term customer success. For our team in Best, we are looking for an experienced Linux / Kubernetes Engineer with a strong background in open-source infrastructure, virtualisation, and Kubernetes. This is not a cloud-first engineering position. We are looking for someone who understands infrastructure from the ground up. Someone who is comfortable working with Linux, virtualisation, Kubernetes, and the networking concepts that connect these layers. The role As a Linux / Kubernetes Engineer, you will design, build, operate, and improve platforms that support mission-critical customer environments. You will work across the infrastructure stack, from Linux and virtualisation through to Kubernetes. Rather than simply consuming an existing managed Kubernetes service, you understand the underlying infrastructure and are comfortable investigating problems across multiple layers of the platform. Your experience does not need to match every technology in our stack. What matters more is that you have strong fundamentals in Linux, virtualisation, and Kubernetes and can apply that knowledge to different infrastructure environments. At Schuberg Philis, engineers work directly with customers and take ownership of the environments they are responsible for. We therefore look for someone who is comfortable speaking up, challenging technical decisions, involving stakeholders, and taking the initiative when something needs to move forward. What you will do Your responsibilities may vary depending on the customer environment, but typically include: • Design, build, operate, and improve Kubernetes-based infrastructure and platforms. • Work extensively with Linux and open-source technologies. • Build and maintain infrastructure across virtualised and Kubernetes environments. • Work with technologies such as Rancher, Harvester, VMware, and related infrastructure platforms. • Troubleshoot complex issues across Linux, virtualisation, Kubernetes, and networking. • Improve the reliability, scalability, and maintainability of infrastructure platforms. • Contribute to infrastructure automation and self-service capabilities for development teams. • Collaborate with network engineers and other infrastructure specialists on platform connectivity and architecture. • Work directly with customer stakeholders to understand technical challenges and translate them into practical solutions. • Take ownership of technical problems instead of waiting for someone else to drive them. • Challenge existing solutions and requirements where you see opportunities to improve them. • Share your knowledge and help strengthen Kubernetes and open-source engineering capabilities across Schuberg Philis. What you bring We are looking for an engineer who understands Kubernetes as part of a wider infrastructure landscape, rather than Kubernetes as an isolated technology. You are comfortable moving between the operating system, virtualisation layer, Kubernetes platform, and networking when investigating or designing infrastructure. You likely bring: • Strong hands-on experience with Linux and open-s
