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: On-Premises Infrastructure Engineering • 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 operatingsystem, 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

Kubernetes Infrastructure Integration • 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, incl
