About NebiusNebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.The RoleWe are looking for a Senior Site Reliability Engineer (SRE) to join the Compute Node team at Nebius AI Cloud. The Compute Node team is responsible for building and operating the cluster scheduler and node-level services that run and manage virtual machines across all cloud regions. This role focuses on Linux systems engineering, virtualization and operational reliability. You will work close to the operating system and hypervisor, shaping how reliability and observability are embedded into the Compute platform.Your Responsibilities Will IncludeEnsure reliability, availability and performance of compute nodes running VMsAnalyze and debug Linux systems across user space and kernel space, understanding capabilities, limitations and trade-offs at each layerTroubleshoot complex production issues involving CPU, memory, NUMA, cgroups and schedulingWork hands-on with virtualization and containerization, primarily using QEMU/KVM and Linux-native technologiesDesign and evolve observability as a core capability of the node layer: metrics, logs, traces, alerts, SLIs and SLOsLead incident response, root-cause analysis, and postmortems, driving long-term reliability improvementsCollaborate closely with platform, kernel/hypervisor, GPU and infrastructure teams to improve system design and operabilityWe Expect You To Have Strong Linux expertise:deep understanding of Linux user space and kernel spaceknowledge of kernel subsystems (scheduler, memory management, filesystems, cgroups, namespaces)clear understanding of system boundaries and constraints at different layersVirtualization experience:hands-on experience with QEMU/KVMunderstanding of VM lifecycle, performance characteristics and failure modesContainerization knowledge:practical experience with containers, namespaces and cgroupsstrong understanding of resource isolation and controlStrong debugging skills:ability to reason about complex system failuresstructured, hypothesis-driven approach to incident analysisSRE mindset:clear understanding of the SRE role in system design and operationsexperience building and operating observability stacks, not just consuming themability to turn system behavior into actionable reliability signalsNice To Have / OptionalExperience with Kubernetes internals or node-level componentsHands-on experience with low-level Linux debugging tools (e.g. perf, eBPF, ftrace, strace, kernel crash dumps)Familiarity with large-scale compute or bare-metal platformsContributions to open-source infrastructure or system softwareExperience debugging hardware and driver-level issues, including GPUs, NVLink, InfiniBandBenefits & PerksCompetitive compensationCareer growth and learning opportunitiesFlexibility and ownershipCollaborative and innovative cultureOpportunity to work on impactful AI projectsInternational environment and talented teamsWhat's It Like To Work At NebiusFast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AIEqual Opportunity StatementNebius is an equal opportunity employer.
