Senior OpenStack Engineer

About the Role
We are seeking a deeply technical Senior Open Stack Engineer to design, build, automate, scale, and operate large-scale production Open Stack 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 Open Stack at the service, database, messaging, hypervisor, and packet-flow layers — individuals who can troubleshoot Rabbit

MQ 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. Open Stack Architecture & Platform Engineering

- Design production-grade Open Stack environments across controller, compute, and storage nodes.
- Architect HA control planes using HAProxy, Keepalived, Galera, and Rabbit

MQ 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.
- Huge Pages 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.
- Blue Store 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, Open Stack-Ansible, Triple

O, and MAAS/Juju.

8. Kubernetes & Containerized Control Planes

- Operate Open Stack 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 Open Stack production operations.
- Strong KVM virtualization expertise.
- Networking: BGP, VXLAN, EVPN.
- Storage:
Ceph production operations.
- Databases:
Maria

DB/Galera.
- Messaging:
Rabbit

MQ.
- Automation:
Ansible/Terraform.
- Scripting:
Python/Bash.

Preferred Skills

- Platform9 / Canonical / Red Hat Open Stack.
- 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.
