Middleware Engineer, Generalist

The opportunity

This position is ideally suited for a technically deep engineer who thrives working across multiple infrastructure domains — contributing both strategically and hands-on. You will play a key role in maintaining resilient platforms, improving operational efficiency through automation, and driving continuous gains in reliability for our internal teams.

We are looking for a collaborative engineer with a proactive mindset who values documentation, knowledge sharing, and continuous improvement — someone who elevates the team around them as much as the infrastructure they manage.

What you'll be doing

• Support and maintain OpenStack infrastructure, ensuring stable integration with storage services while continuously contributing to the ongoing operation, improvement, and scalability of the platform.
• Administer and optimise Ceph storage clusters, overseeing cluster health, capacity planning, performance tuning, reliability, and all day-to-day operational responsibilities across the storage environment.
• Perform comprehensive Linux systems administration across infrastructure environments, including provisioning, configuration management, patching, performance tuning, troubleshooting, and full lifecycle management.
• Automate operational workflows using scripting languages and infrastructure automation tools such as Ansible to drive consistency, scalability, and efficiency across Ceph, OpenStack, and Linux platforms.
• Troubleshoot complex, cross-platform infrastructure issues spanning storage, compute, networking, and operating systems — conducting thorough root-cause analysis and implementing long-term, sustainable improvements.

What we're looking for

• Solid experience working with OpenStack in an operational or engineering capacity, with a strong understanding of its integration with underlying storage and networking layers.
• Demonstrated expertise in Ceph storage administration, including cluster operations, configuration, health monitoring, troubleshooting, and performance tuning in production environments.
• Strong Linux systems administration skills, with proven experience managing and maintaining production Linux environments at scale.
• Hands-on experience with automation, scripting, and infrastructure-as-code tooling for provisioning, configuration management, and operational workflow optimisation.
• Strong knowledge of Linux and host networking, with the ability to troubleshoot and problem-solve effectively across distributed systems and complex infrastructure services.

You might also have

• Experience with monitoring and observability platforms such as Prometheus, Grafana, or the ELK Stack.
• Familiarity with network infrastructure configuration, including switches and routers.
• Knowledge of security best practices, including hardening, patching, and compliance considerations in enterprise infrastructure environments.
• Experience with disaster recovery, backup strategies, and business continuity planning.
• Exposure to public cloud platforms such as AWS, Azure, or Google Cloud.

• Relocation support is not available for this position
• Work visa/immigration sponsorship is not available for this position
