  • ● Lead infrastructure incident response, troubleshooting, escalation, and post-incident improvements.
  • ● Maintain on-call processes and operational coverage across distributed environments.
  • ● Work close to the hardware layer, including IPMI/Redfish, BMCs, RAID, storage, hardware diagnostics, and GPU infrastructure.
  • ● Manage virtualization platforms including Proxmox VE and KVM/libvirt, including GPU passthrough where required.
  • ● Build and maintain internal infrastructure tooling for host discovery, configuration, IPAM, hardware health, and operational automation.
  • ● Own infrastructure lifecycle activities including site onboarding, maintenance, decommissioning, drift detection, and operational runbooks.
  • ● Work closely with engineering and cross-functional teams to improve reliability, resource utilization, and operational efficiency.
  • ● + years of hands-on SRE, Infrastructure, Systems, or Platform Engineering experience.
  • ● Expert-level Linux administration, particularly Debian/Ubuntu.
