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.
