Senior OpenStack Engineer

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. - 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.
