OpenStack Administrator

Key Responsibilities:

- Plan and deploy OpenStack environments from the ground up - controller, compute, storage, and network nodes across development and production.

- Install and configure core OpenStack services including Keystone (identity), Nova (compute), Neutron (networking), Glance (images), Cinder (block storage), Swift (object storage), and Horizon (dashboard).

- Use deployment tooling such as Kolla-Ansible, TripleO, OpenStack-Ansible, or Juju/MAAS for repeatable, automated builds.

- Design and implement high-availability architectures for control-plane services, message queues (RabbitMQ), and databases (MariaDB/Galera).

- Configure Ceph or equivalent backend storage integration for Cinder, Glance, and Nova ephemeral storage.

- Perform day-to-day administration of the OpenStack environment - projects, tenants, quotas, flavors, images, and user access.

- Provision and manage instances, virtual networks, routers, floating IPs, security groups, and load balancers on behalf of internal consumers.

- Execute OpenStack version upgrades, patching, and service restarts with minimal disruption to running workloads.

- Monitor platform health, capacity, and performance; forecast growth and plan compute, storage, and network expansion.

- Troubleshoot and resolve issues across compute, networking (OVS/OVN), storage, and control-plane services using service logs and CLI/API diagnostics.

- Install and administer Linux operating systems (RHEL, CentOS, Ubuntu) that host OpenStack services and compute nodes.

- Manage LVM - physical volumes, volume groups, and logical volumes - including resizing, extending, and snapshot operations.

- Configure file systems, disk partitioning, storage mounts, and kernel/system-level performance tuning.

- Handle patching, user and permission management, SSH access, systemd services, and security hardening across the Linux estate.

- Automate operational and diagnostic tasks with shell scripting (Bash) and scheduled jobs.

Requirements:

- 4 - 5 years of relevant experience in deploying, managing, and maintaining production OpenStack environments.

- Basic understanding of networking fundamentals.

- Understanding of Kubernetes architecture and managing clusters, control plane, networking and storage of cluster is added advantage.

- Candidate who has knowledge of VMWARE architecture and its administration would be preferred.

- Candidate must be willing to work on any new hypervisor technology and willing to develop deep understanding of hypervisor.

- Familiarity with Helm, GitOps workflows, and CI/CD tooling (Jenkins, GitLab CI, or GitHub Actions).

- Conduct POC for the products and demonstrate the clusters and its working.
