About the Client

Our client is a global leader in aviation technology, delivering innovative IT and communications solutions that connect airlines, airports, aircraft and governments worldwide. Operating in over 200 countries and territories, they play a critical role in enabling the safe, secure and efficient movement of millions of passengers every day.

About the Role

The Senior Infrastructure & Storage Engineer owns the implementation, integration, testing, and engineering lifecycle of on-premises compute, Linux, distributed storage, and related data-centre infrastructure.

The role translates approved architecture into reliable, resilient, supportable platforms and provides deep engineering support for complex infrastructure incidents.

This is a senior, hands-on role with particular emphasis on bare-metal infrastructure, Ceph, MinIO, Linux, Kubernetes storage integration, capacity, backup and recovery, and operational knowledge transfer. The engineer works closely with Platform Architecture, Operations, Kubernetes & Platform Engineering, Network Engineering, Security, vendors, and delivery teams

Key Responsibilities

• Build, configure, troubleshoot, and lifecycle-manage physical and virtual servers across heterogeneous data-centre environments.
• Engineer and support CentOS, RHEL, or equivalent Linux platforms, including operating-system, service, package, certificate, disk, memory, process, and performance issues.
• Execute data-centre refreshes, hardware deployments, firmware and operating-system changes, and replacement activities in accordance with approved designs.
• Validate compute, network, storage, power, capacity, resilience, monitoring, and support dependencies before production acceptance.
• Support selected Windows infrastructure where required.

Distributed Storage and Data Protection

• Administer and troubleshoot Ceph, including cluster health, OSDs, monitors, placement groups, pools, capacity, performance, replication, and failure domains.
• Engineer and support distributed MinIO deployments, object-storage availability, capacity healing, replication, and recovery.
• Diagnose storage latency, degraded redundancy, disk and node failures, data-path issues, and capacity risks using an evidence-based approach.
• Plan, document, and test backup, restoration, disaster recovery, and data-protection procedures; distinguish platform redundancy from backup.
• Coordinate specialist and vendor escalation for high-risk or complex storage problems
• Support bare-metal Kubernetes nodes and their operating-system, hardware, network, containerruntime, and storage dependencies.
• Engineer and troubleshoot Kubernetes persistent storage, CSI drivers, StorageClasses, persistent volumes, mounts, and Ceph-backed workloads.
• Collaborate with the Kubernetes & Platform Engineer during cluster upgrades, node maintenance, capacity changes, recovery testing, and stateful workload incidents.
• Understand core Kubernetes concepts sufficiently to diagnose whether failures originate in the workload, node, network, CSI, storage, or underlying infrastructure.

Automation, Monitoring, and Capacity

• Automate repeatable infrastructure provisioning and configuration using Terraform, Ansible, Bash, Python, or equivalent tools.
• Use Git-based workflows so infrastructure changes are reviewable, auditable, and reproducible.
• Implement Prometheus metrics, dashboards, and actionable alerts for hosts, hardware, Ceph, MinIO, storage paths, capacity, and backup health.
• Track utilization, saturation, growth, hardware health, and redundancy; implement shortand mediumterm capacity actions.
• Integrate infrastructure logs and telemetry with platforms such as New Relic and Elasticsearch where appropriate.

Testing, Handover, and Engineering Support

• Plan and execute functional, integration, resilience, failover, capacity, backup, restoration, upgrade, and rollback testing.
• Define acceptance criteria, evidence, abort conditions, maintenance procedures, and safe recovery paths.
• Provide Level 3 support, lead root-cause analysis, and implement permanent corrective actions for complex infrastructure incidents.
• Produce practical SOPs, runbooks, diagrams, asset and dependency records, maintenance procedures, and escalation paths.
• Conduct hands-on knowledge transfer and ensure routine operations can be performed safely without dependency on one engineer.

What we are looking for

Required Skills

Strong recent, hands-on experience engineering and troubleshooting production on-premises infrastructure.

• Advanced Linux systems administration and troubleshooting capability.
• Strong experience with storage systems and data-protection concepts, including replication, quorum, failure domains, capacity, performance, backup, and recovery.
• Practical production experience with Ceph or a closely comparable distributed storage platform.
• Experience working with physical servers, disks, controllers/HBAs, firmware, operating systems, virtualization, and data-centre dependencies.
• Experience automating infrastructure through Ansible, Terraform, Bash, Python, or equivalent technologies.
• Experience implementing monitoring, alerting, capacity management, and operational procedures.
• Strong incident troubleshooting, root-cause analysis, risk management, and vendor escalation skills.
• Ability to produce clear documentation and transfer specialist knowledge effectively.
• Direct administration of Ceph in production, including recovery from degraded states and performance investigations.
• Distributed MinIO on dedicated servers or bare-metal infrastructure.
• Kubernetes, Rancher, RKE2/RKE, CSI, and persistent-volume integration.
• Prometheus, New Relic, Elasticsearch, or comparable observability platforms.
• MariaDB, PostgreSQL, or other infrastructure database administration.
• CentOS/RHEL, virtualization, selected Windows infrastructure, and hybrid Azure integration.
• Business-continuity and disaster-recovery exercises across multiple data centres.

Candidates do not need to be application-platform or cloud specialists. Depth in Linux, on-premises infrastructure, distributed storage, safe recovery, and operational knowledge transfer is more important than matching every desirable product.
