Job Description
OpenStack Infrastructure Engineer building and scaling xneelo’s reliable web hosting compute and storage infrastructure. Operating OpenStack, Ceph and Linux systems in a distributed team.
Responsibilities:
- Build, manage and scale OpenStack compute and storage infrastructure
- Operate and troubleshoot open-source infrastructure systems
- Implement, operate and troubleshoot OpenStack environments
- Manage distributed storage systems such as Ceph, including capacity, replication, failure domains, recovery, latency and performance
- Troubleshoot compute, storage, physical and virtual networking, databases, message queues, containers, hypervisors and guest workloads
- Plan and execute infrastructure upgrades, migrations and high-impact changes
- Manage end-to-end infrastructure from physical systems and network fabric through OpenStack services to customer workloads
- Use Infrastructure as Code, configuration management and automation to deliver repeatable, version-controlled operations
- Document architecture decisions, runbooks, change plans, incident findings and recovery procedures
- Participate in technical reviews and provide or respond to detailed feedback
- Participate in Rootly-managed on-call rotation and respond to occasional out-of-hours incidents, maintenance or operational requests
- Use AI-assisted tools for research, troubleshooting, documentation and automation while applying engineering judgement, peer review and testing
- Collaborate effectively in a distributed, largely asynchronous team
Requirements:
- Experience operating open-source infrastructure systems; extensive experience expected at senior level
- OpenStack implementation, operations or troubleshooting experience
- Experience with Ceph or similar distributed storage systems, including capacity, replication, failure domains, recovery, latency and performance
- Strong Linux systems administration and troubleshooting skills
- Practical knowledge of data-centre-grade hardware, including enterprise servers, CPUs, memory, storage media, NICs, firmware and out-of-band management
- Understanding of how hardware design, power, cooling, rack layout and component failure affect platform reliability and performance
- Strong networking fundamentals; experience in OVN, OVS, BGP underlays, LACP, Juniper, IPv4, IPv6 and physical or virtual cloud networks advantageous
- Ability to troubleshoot across compute, storage, physical and virtual networking, databases, message queues, containers, hypervisors and guest workloads
- Experience with virtualisation and cloud infrastructure at scale
- Security-minded approach to architecture, automation, access control and operational workflows
- SRE mindset focused on reducing failure probability, recovery time, operational risk and data-loss exposure
- Experience with Infrastructure as Code, configuration management and automation practices
- Preference for repeatable, version-controlled automation over undocumented manual work
- Discipline when planning and executing upgrades, migrations and high-impact infrastructure changes
- Strong end-to-end ownership from physical infrastructure and network fabric through OpenStack services to customer workloads
- Ability to reason about capacity and performance across CPU, memory, storage, IOPS, latency, throughput, packet rates and control-plane scale
- Ability to use AI-assisted tools productively while understanding their limitations
- Clear technical documentation skills, including architecture decisions, runbooks, change plans, incident findings and recovery procedures
- Ability to contribute constructively to technical reviews, challenge unsafe assumptions and respond well to detailed feedback
- Ability to work effectively in a distributed, largely asynchronous team
- Willingness to participate in an on-call rotation managed through Rootly and respond to occasional out-of-hours incidents, maintenance or operational requests
- Experience with a reasonable number of Ubuntu Linux, Ansible, OpenStack, Ceph, Terraform, Rundeck, LXC, Nspawn, OVN, OVS, BGP, JunOS, LACP, Docker, Prometheus, Grafana, Git, Jira or similar tools
Benefits:
- Salary negotiable, commensurate with skills and track record
- High level of discretion and autonomy
- Distributed, largely asynchronous team
- Opportunity for autonomy, mastery and purpose
- Meaningful opportunity to work on world-class compute and storage hosting platforms
