Senior Linux Administrator

Overview

Own the operational health, efficiency and observability of a large Linux compute farm serving NVIDIA's VLSI design teams, supporting the Infrastructure team that designs and optimizes compute infrastructure for silicon design and AI workloads.

What you'll do

• Own the operational health, efficiency and observability of a large Linux compute farm serving NVIDIA's VLSI design teams.
• Profile and debug at the system level (kernel, filesystem, memory and I/O behaviour) when workloads are slow, and turn findings into fixes rather than tickets.
• Drive compute efficiency: memory request-versus-usage accuracy, CPU waste from idle and over-provisioned jobs, and the prediction models behind resource requests.
• Build the observability layer for the farm: telemetry pipelines, metrics and dashboards that make capacity, utilisation and job behaviour visible to engineers and leadership.
• Own licence monitoring and expiry alerting across the EDA tool estate.
• Perform day-to-day farm operations and live triage, working directly with the heaviest users on their workload behaviour.

What you'll need

• B.E./B.Tech/M.Tech in Computer Science, Electrical Engineering, or equivalent experience.
• 8+ years in Linux systems administration or infrastructure operations at scale.
• Deep Linux systems and kernel-level expertise, comfortable with perf, eBPF/bpftrace, strace, cgroups, NUMA, memory management, scheduler behaviour and I/O subsystems, and able to use them to find root cause.
• Demonstrated experience diagnosing and fixing performance problems on large multi-user compute systems.
• Strong NFS and distributed filesystem troubleshooting: metadata versus data path, client behaviour, mount and latency issues.
• Hands-on experience building observability: time-series metrics, log and telemetry pipelines, and dashboards (Prometheus/Grafana, Elastic, or equivalent).
• Strong Python for analysis and automation.
• Familiarity with batch schedulers (LSF, Slurm, or equivalent) and job resource accounting.
• A genuine appetite for operational work.

Nice to have

• Semiconductor/EDA or HPC background.
