Senior OpenStack Engineer - US

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.

1. 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.

1. 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.

1. 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.

1. Image & Lifecycle Services

• Glance image pipelines.
• QCOW2 optimization.
• Cloud-init automation.
• Golden image lifecycle management.

1. Identity & Access (Keystone)

• RBAC modeling.
• LDAP/AD integration.
• SAML/SSO federation.
• Token lifecycle management.

1. Orchestration & Automation

• Heat orchestration templates.
• Terraform automation.
• Ansible playbooks.
