Careers at redu.cloud

About the role

As an OpenStack Cloud Engineer you will design, build, and operate highly available cloud infrastructure. You will work across compute, networking, and storage to deliver a reliable platform for our customers.

Responsibilities

• Design, deploy and operate OpenStack services in production (e.g., Nova, Neutron, Cinder, Keystone, Glance, Swift).
• Build robust virtualization stacks using KVM/QEMU and libvirt.
• Plan and implement software-defined networking (SDN) using OVS/OVN and related technologies; troubleshoot L2/L3 networking, VLAN/VXLAN overlays, routing, security groups.
• Operate and tune cloud storage platforms (e.g., Ceph RBD/Obj, Cinder backends) for performance and reliability.
• Automate infrastructure with Ansible; maintain infrastructure-as-code best practices.
• Monitor, log, and capacity-plan production systems; participate in on-call rotations and incident response.
• Collaborate with engineering and support to deliver platform features and resolve customer issues.

Requirements

• 3+ years of hands-on experience operating OpenStack in production or large-scale private clouds.
• Strong virtualization skills (KVM/QEMU, libvirt; understanding of CPU, memory, NUMA, live migration).
• Solid SDN/networking knowledge: OVS/OVN, Neutron, VLAN/VXLAN, routing/BGP, firewalls/security groups, load balancing.
• Cloud storage expertise: Ceph (RBD/Obj), Cinder backends, multipath/iSCSI/NVMe-oF fundamentals.
• Linux systems engineering (Ubuntu/Debian/CentOS), shell scripting, and performance troubleshooting.
• Automation with Ansible; Git-based workflows and CI/CD familiarity.
• Programming/scripting in Python and/or Bash for tooling and integrations.
• Security and hardening best practices across compute, network, and storage layers.
• Clear communication in English; ability to document architectures and runbooks.

Nice to have

• Experience with Kubernetes on OpenStack, or container networking/storage.
• Operating Ceph at scale (RGW/Swift API, CRUSH maps, tuning, upgrades).
• Observability stacks (Prometheus, Grafana, Loki/ELK) and alerting design.
• Certifications: COA (OpenStack), CKA/CKAD, RHCE, or similar.
