• Build automation and improve runbooks, dashboards, alerts, and lifecycle workflows.
• Collaborate with teams across Core Weave, external vendors, and customer‑facing stakeholders.
• Drive assigned work to completion with clear communication, thoughtful prioritization, and early visibility into risks or blockers.
• Participate in on‑call, incident response, root cause analysis, and follow‑up improvements.
• Contribute to reliable workflows that scale across regions, platforms, and fleet growth, with ownership calibrated by level.

• Strong Linux system administration and troubleshooting skills.
• Networking fundamentals and common troubleshooting tools.
• Production debugging experience using logs, metrics, and command‑line tools.
• Server, network, GPU, or data center hardware troubleshooting experience.
• Practical scripting or automation experience in Python, Go, Bash, or similar.
• Clear communication, documentation, collaboration, and on‑call readiness.
• Curiosity to learn specialized GPU interconnect technologies such as NVLink, NVSwitch, and Infini Band.

• Ansible or other infrastructure automation tooling.
• Kubernetes application development or operations experience.
• Grafana, Prometheus, PromQL, or similar observability systems.
• Large fleet operations across Linux systems, network devices, GPUs, or infrastructure components.
• Infini Band, RDMA, HPC networking, or low‑latency/high‑bandwidth fabrics.
• BMC, Redfish, IPMI, firmware lifecycle management, or hardware management APIs.
• NVLink, NVSwitch, NVIDIA GPU platforms, NVUE, SONiC, or network operating systems.

The base salary range for this role is £79,000 to £105,000. The starting salary will be determined based on job‑related knowledge, skills, experience, and market location. In addition to base salary, our total rewards package includes a discretionary bonus, equity awards, and a comprehensive benefits program (all based on eligibility).
