Senior Infrastructure & Storage EngineerSummaryLocation:Barcelona (Hybrid)Rate:NegotiableDuration:6 MonthsAbout the ClientOur 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 RoleThe 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 teamsKey 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 problemsKubernetes 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 forRequired SkillsStrong 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.Desirable Experience* 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.
