Description

  • Ensure the reliability, availability, and performance of compute nodes running virtual machines.
  • Analyze and debug Linux systems across user space and kernel space, including trade-offs and boundaries at each layer.
  • Troubleshoot complex production issues involving CPU, memory, NUMA, cgroups, and scheduling.
  • Work hands-on with virtualization and containerization technologies, primarily QEMU/KVM and Linux-native tools.
  • Design and evolve observability for the node layer, including metrics, logs, traces, alerts, SLIs, and SLOs.
  • Lead incident response, root-cause analysis, and postmortems to drive long-term reliability improvements.
  • Collaborate with platform, kernel/hypervisor, GPU, and infrastructure teams to improve system design and operability.

Requirements

  • Strong Linux expertise, including deep understanding of Linux user space and kernel space.
  • Knowledge of kernel subsystems such as scheduler, memory management, filesystems, cgroups, and namespaces.
  • Hands-on experience with QEMU/KVM and understanding of VM lifecycle, performance characteristics, and failure modes.
  • Practical experience with containers, namespaces, and cgroups, with strong understanding of resource isolation and control.
  • Strong debugging skills and a structured, hypothesis-driven approach to incident analysis.
  • Clear understanding of the SRE role in system design and operations.
  • Experience building and operating observability stacks, not just consuming them.
  • Ability to turn system behavior into actionable reliability signals.
  • Experience with Kubernetes internals or node-level components is a plus.
  • Experience with low-level Linux debugging tools such as perf, eBPF, ftrace, strace, and kernel crash dumps is preferred.
  • Familiarity with large-scale compute or bare-metal platforms is preferred.
  • Contributions to open-source infrastructure or system software are preferred.
  • Experience debugging hardware and driver-level issues, including GPUs, NVLink, and InfiniBand, is preferred.

Benefits

  • Competitive salary and comprehensive benefits package.
  • Opportunities for professional growth within Nebius.
  • Flexible working arrangements.
  • A dynamic and collaborative work environment that values initiative and innovation.
