About the Role

We are seeking a deeply technical Senior OpenStack Engineer to design, build, automate, scale, and operate large-scale production OpenStack environments powering enterprise private clouds, MSP platforms, and high-performance digital twin lab infrastructures. This is not a UI-driven admin role. We are looking for engineers who understand OpenStack at the service, database, messaging, hypervisor, and packet-flow layers — individuals who can troubleshoot RabbitMQ queues, debug Neutron agents, tune Ceph latency, and automate full cloud deployments from bare metal upward. You will work on multi-region architectures, high-availability designs, NVMe storage fabrics, SDN integrations, and hybrid cloud platforms supporting global customers. Primary Responsibilities 1. OpenStack Architecture & Platform Engineering - Design production-grade OpenStack environments across controller, compute, and storage nodes. - Architect HA control planes using HAProxy, Keepalived, Galera, and RabbitMQ clustering. - Build scalable cell-based Nova architectures. - Implement multi-region replication strategies. - Perform platform capacity modeling and growth forecasting. 2. Compute Virtualization (Nova) - Nova scheduler tuning and filters. - CPU pinning and isolation. - NUMA topology alignment. - HugePages configuration. - Live migrations and evacuations. - GPU passthrough and SR-IOV provisioning. Hypervisor stack includes KVM, QEMU, Libvirt, and VirtIO. 3. Networking & SDN (Neutron) - ML2 plugin architecture. - OVS, OVN, Linux Bridge deployments. - VXLAN, Geneve, VLAN overlays. - DVR and L3 routing. - Floating IP NAT design. - SR-IOV and DPDK acceleration. - Integration with BGP EVPN, MPLS, VRFs, and SD-WAN. 4. Storage Engineering Ceph (Primary Requirement) - RBD block storage. - CephFS and RGW object storage. - CRUSH map tuning. - Placement group optimization. - BlueStore performance tuning. - NVMe and SSD tiering. Additional exposure to Linstor, DRBD, iSCSI, and NVMe-oF preferred. 5. Image & Lifecycle Services - Glance image pipelines. - QCOW2 optimization. - Cloud-init automation. - Golden image lifecycle management. 6. Identity & Access (Keystone) - RBAC modeling. - LDAP/AD integration. - SAML/SSO federation. - Token lifecycle management. 7. Orchestration & Automation - Heat orchestration templates. - Terraform automation. - Ansible playbooks.
