Software Engineer

Job Description

Cloud Infrastructure & Virtualization Engineer Role overview We are hiring an Infrastructure & Virtualization Engineer to design, build, operate and document a KVM-based private cloud platform. The role spans Linux and KVM, servers, networking, storage, software-defined networking and the databases that support platform services. Item Detail Job title Cloud Infrastructure & Virtualization Engineer Department Infrastructure / Cloud Platform Engineering Employment type Full-time Experience 2–4 years in Linux, virtualization and data-centre infrastructure Location on-site Reports to Infrastructure Manager / Platform Engineering Lead The engineer will own day-to-day platform health, lead troubleshooting across compute, network and storage layers, and keep technical documentation for every system they touch clear.

Key responsibilities Virtualization & compute platform Install, configure and maintain KVM/QEMU hypervisors and manage VMs through libvirt, virsh and virt-manager (or platforms such as OpenStack, Proxmox or oVirt). Provision, clone, snapshot, migrate (live and cold) and decommission virtual machines and templates. Plan capacity for CPU, memory and storage; tune performance with CPU pinning, NUMA awareness, huge pages and virtio drivers.

Maintain high availability for hypervisor clusters and handle host maintenance with minimal downtime. Linux & server administration Administer enterprise Linux (RHEL, Rocky, Ubuntu, Debian): packages, services, kernel parameters, users, permissions and SELinux/AppArmor. Configure and maintain physical servers, including BIOS/UEFI, RAID controllers, firmware and out-of-band management (iDRAC, iLO, IPMI).

Diagnose hardware faults and coordinate replacements with vendors. Automate routine tasks with Bash or Python and configuration tools such as Ansible. Networking & SDN Configure Linux networking: bridges, bonding/LACP, VLANs, routing and firewalls (iptables/nftables, firewalld).

Design and operate virtual networks using Open vSwitch, VXLAN/GENEVE overlays and SDN controllers (e.g. OVN, OpenStack Neutron, OpenDaylight). Work with the network team on switching, routing (OSPF/BGP basics), load balancing, DNS and DHCP.

Troubleshoot connectivity with tcpdump, Wireshark, ip, ss and traceroute. Storage Manage block, file and object storage for VMs: LVM, iSCSI, NFS, Fibre Channel and SAN/NAS arrays. Allocate and expand volumes, manage storage pools and qcow2/raw images, and monitor capacity and IOPS.

Support distributed storage such as Ceph or GlusterFS where deployed. Database management Install, configure and maintain databases used by platform services (MySQL/MariaDB, PostgreSQL; familiarity with NoSQL a plus). Handle backups, restores, user access, replication, query performance and routine health checks.

Technical documentation Write and maintain architecture diagrams, build guides, runbooks, SOPs, network and IP plans, and change records. Document incidents with root-cause analysis and record lessons learned. Keep a knowledge base current so other engineers and the support team can operate the platform.

Operations & support Monitor the platform and respond to alerts and incidents within SLA. Follow ITIL change, incident and problem management processes. Apply security patches and hardening baselines across hosts and guests.

Join an on-call rotation as required. Skills matrix Skills are grouped into the buckets most job portals and hiring teams use: primary, secondary and good to have, with a tools list for keyword matching. Proficiency: Advanced = designs and owns independently; Intermediate = handles routine work independently; Basic = understands concepts, works with guidance.
