Senior Linux Infrastructure Engineer (Bare metal & storage)

Job description

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.
