Senior OpenStack Engineer

About the RoleWe 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 Responsibilities1. 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 EngineeringCeph (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.- CI/CD for infrastructure.Deployment frameworks include Kolla-Ansible, OpenStack-Ansible, TripleO, and MAAS/Juju.8. Kubernetes & Containerized Control Planes- Operate OpenStack on Kubernetes.- Helm/Operator-based deployments.- Pod and persistent volume troubleshooting.9. Bare Metal Provisioning (Ironic)- PXE/iPXE pipelines.- Hardware introspection.- Integration with MAAS/Foreman.10. Observability & Reliability Engineering- Prometheus and Grafana monitoring.- ELK logging pipelines.- Incident response and RCA.- SLA tracking and alert tuning.11. Upgrade & Lifecycle Management- Major version upgrades.- Rolling compute upgrades.- Database migrations.- Zero-downtime patching.Required Technical Experience- 8–12+ years Linux systems engineering.- 5+ years OpenStack production operations.- Strong KVM virtualization expertise.- Networking: BGP, VXLAN, EVPN.- Storage: Ceph production operations.- Databases: MariaDB/Galera.- Messaging: RabbitMQ.- Automation: Ansible/Terraform.- Scripting: Python/Bash.Preferred Skills- Platform9 / Canonical / Red Hat OpenStack.- Ironic bare-metal provisioning.- DPDK / SR-IOV acceleration.- GPU workloads.- Hybrid cloud integrations.Work Model Requirements- Remote within India.- Mandatory U.S. EST shift overlap.- Night shift operations required.- On-call rotation participation.
