Senior Linux Infrastructure Engineer (Bare metal & storage)

Job Overview :

We are looking for a highly experienced Linux Infrastructure Engineer with deep expertise in traditional Linux administration, bare metal infrastructure, and enterprise storage. This role is not focused on DevOps or cloud-native engineering. We already have a strong DevOps team and are looking for someone with extensive hands-on experience designing, building, administering, and troubleshooting large-scale Linux infrastructure.

Key Responsibility & Required Skills

• Expert-level Linux administration (Ubuntu required; Red Hat and SUSE preferred)
• Deep expertise in bare metal server deployment, architecture, and administration
• Strong understanding of server hardware, including BIOS, RAID, firmware, iLO/iDRAC/IPMI, NICs, HBA cards, and hardware troubleshooting
• Experience designing and administering enterprise Linux infrastructure
• Advanced Linux storage administration:
  • LVM
  • XFS, EXT4
  • NFS
  • iSCSI
  • Fibre Channel SAN
  • Multipath I/O
• Strong hands-on experience with Ceph, including:
  • Cluster architecture
  • MON, OSD, MDS
  • RBD, CephFS, RGW
  • Capacity planning
  • Performance tuning
  • Failure recovery
• Strong networking knowledge (bonding, VLANs, routing, MTU, DNS, DHCP)
• Experience with high availability, clustering, and disaster recovery
• Strong troubleshooting skills across Linux OS, hardware, networking, and storage
• Bash and Python scripting for automation

Nice to Have

• Kubernetes infrastructure (especially storage integration)
• VMware or KVM
• Ansible
• AWS/Azure exposure

We are not looking for

• Candidates whose experience is primarily CI/CD pipeline engineering
• Engineers focused mainly on Terraform, GitOps, or container platforms
• Cloud-only administrators with limited bare metal or infrastructure experience

Ideal candidate: Someone who has spent years running enterprise Linux environments, building servers from the hardware up, architecting storage platforms, and solving complex OS, hardware, and storage issues. DevOps experience is a plus, but traditional Linux infrastructure expertise is the primary requirement.
