## About the Role

The ideal candidate has extensive experience in site reliability engineering, Linux infrastructure, and distributed systems, with a strong ability to debug and optimize complex production environments.
Deep expertise in Linux systems, including user space, kernel space, and core kernel subsystems such as scheduling, memory management, filesystems, cgroups, and namespaces.
Strong understanding of system architecture, boundaries, and performance trade?offs across different infrastructure layers.
Hands?on experience with virtualization technologies, particularly QEMU/KVM, including VM lifecycle management and performance optimization.
Practical experience with container technologies, namespaces, and resource isolation mechanisms.
Strong debugging and problem?solving skills with a structured, hypothesis?driven approach to incident investigation.
Solid understanding of SRE principles, including reliability engineering, system design, and operational ownership.
Experience building and operating observability solutions rather than only consuming monitoring tools.
Ability to translate system behavior into actionable reliability improvements.
Experience with Kubernetes internals, node?level components, or large?scale compute platforms is a plus.
Familiarity with low?level Linux debugging tools such as perf, eBPF, ftrace, strace, or kernel crash analysis is beneficial.
Experience with hardware?level debugging, GPU infrastructure, NVLink, InfiniBand, or open?source infrastructure projects is considered an advantage.
