About the Role.

We're looking for a hands-on private-cloud engineer who can take an OpenStack-based platform from bare metal to a working, accepted, and supportable production environment — and then own it through its operational lifecycle.

This is a greenfield deployment covering compute, software-defined storage, GPU enablement, Kubernetes, and an AI/ML platform. You'll lead or contribute to technical delivery, automation, capacity growth, operational improvement, resilience testing, documentation, and training of the internal cloud team.

This is not a role for someone who has only consumed OpenStack through a dashboard. We need someone who has deployed it, broken it, recovered it, automated it, and documented it — using Kolla Ansible as the deployment tooling.

The role combines architecture input with hands-on engineering. You won't be expected to single-handedly deliver every specialist subsystem without support, but you must understand the full platform and be able to troubleshoot across its major layers.

What You will do.

Deployment & Architecture

- Design and deploy a multi-node OpenStack private cloud using Kolla Ansible
- Configure a highly available control plane and define service placement, failure domains, and network segmentation (management, API, provider, tenant, external)
- Deploy and configure core services: Keystone, Nova, Placement, Glance, Neutron, Cinder, Horizon
- Maintain version-controlled inventory, configuration, and secrets-management procedures
- Produce architecture documents, capacity plans, and implementation runbooks

Storage
- Design and deploy a distributed software-defined storage platform (Ceph preferred) as the shared substrate
- Integrate block/image storage with Glance, Cinder, and Nova; stand up an S3-compatible object endpoint
- Define replication/erasure-coding policies, failure domains, and capacity thresholds
- Validate failure, degraded-mode, and recovery behaviour

Networking & Security
- Design and configure management,



API, provider, tenant, storage, and tunnel networks
- Implement VLANs, overlays, routing, firewalling, and security groups per the organisation's addressing standards
- Apply security-hardening baselines and maintain compliance evidence

Compute & Workloads
- Build and maintain golden images and flavour catalogues (CPU, memory, NUMA, huge pages, GPU profiles)
- Configure host aggregates, availability zones, and placement/scheduling policies
- Restore and re-platform existing Windows and Linux workloads into the current environment

GPU Enablement
- Enable GPU access end-to-end: firmware, BIOS, IOMMU, kernel parameters, drivers, device binding
- Configure PCI passthrough or vGPU as required; configure Nova PCI aliases, traits, and scheduler filters
- Expose GPU resources to Kubernetes worker nodes via appropriate device plugins

Kubernetes & AI/ML Platform
- Deploy and operate a highly available Kubernetes cluster on the private cloud
- Configure CNI, ingress, RBAC, CSI-backed persistent storage, and GPU-schedulable nodes
- Deploy an approved AI/ML workspace platform (notebooks, training jobs, model serving) with per-project isolation and quotas

Identity & Enterprise Integration
- Integrate with the organisation's enterprise directory; configure SSO/federation across OpenStack, Kubernetes, and the AI workspace
- Implement role mapping, least-privilege access, and credential-rotation procedures

Monitoring, Logging & Audit
- Implement monitoring/alerting across hosts, OpenStack services, storage, VMs, Kubernetes, and GPU utilisation
- Configure centralised logging, audit collection, and alert escalation

Resilience, Backup & Recovery
- Define and execute resilience tests (compute/controller/storage/network/Kubernetes/GPU/identity failure scenarios)
- Validate backup/restore against agreed RTO/RPO targets
- Produce test plans, execution evidence, and resilience reports

Restricted-Network Delivery
- Build and maintain internal package repositories and private container registries
- Prepare an offline bill of materials (packages, images, charts, drivers, firmware, licenses)
- Establish controlled import, scanning, signing, and promotion procedures
- Ensure deployment, patching, and recovery can operate without dependency on public internet access

Lifecycle Ownership (post go-live)

- Own technical evolution: capacity expansion, tuning, upgrades, automation




- Act as escalation point for platform issues; lead root-cause analysis
- Maintain architecture documents, SOPs, and runbooks
- Train the internal cloud engineering team to independent competency

Experience we Need.

Core

- 6+ years infrastructure/platform-engineering experience; 3+ years hands-on OpenStack
- Demonstrable delivery of at least one production OpenStack environment from install through acceptance
- Evidence of personal technical contribution, not just project oversight

OpenStack & Kolla Ansible
- Strong working knowledge of Keystone, Nova, Placement, Glance, Neutron, Cinder, Horizon
- Hands-on Kolla Ansible: inventory, globals config, secrets handling, bootstrap, prechecks, deployment, validation, upgrades
- Ability to troubleshoot containerised OpenStack services and deployment failures

Storage

- Hands-on experience with a distributed SDS platform (Ceph preferred)
- Experience integrating storage with Glance/Cinder/Nova and Kubernetes CSI

Linux, Compute & Networking
- Deep Linux systems engineering (kernel, drivers, systemd, networking, storage stacks)
- Strong KVM/QEMU understanding
- VLANs, overlays, routing, firewalling, DNS, NTP, load balancing

Kubernetes & AI Platforms
- Production Kubernetes deployment and operation experience
- GPU scheduling via vendor device plugins
- AI/ML platform deployment (notebooks, training, model serving) strongly preferred

GPU Virtualisation

- PCI/IOMMU passthrough, device binding, driver installation and validation in VMs/containers

Identity, Observability & Automation
- Enterprise directory integration, SSO/RBAC, certificate and secrets management
- Strong Python/shell scripting and Ansible or equivalent IaC experience

Restricted-Network Environments
- Demonstrable experience delivering in air-gapped or restricted-network environments
- Comfortable with formal change control, security review, and audit evidence

Desirable.

- Ceph RBD, CephFS, RADOS Gateway
- Octavia, Barbican, Ironic, Heat, Swift, Manila
- Kubeflow, JupyterHub, MLflow, Ray, KServe, vLLM, or comparable AI/ML platforms
- NVIDIA GPU operators or equivalent vendor tooling
- Multi-site disaster recovery experience
- CKA / CKS / Linux / OpenStack certifications (supplementary to delivery evidence, not a substitute
