Senior Infrastructure Engineer — Hyper-V in Glasgow

5 Days Onsite for Glasgow. Job Description Senior Infrastructure Engineer — Hyper-V Virtualization & Infrastructure Engineering We're looking for a talented, senior engineering professional ready to take their career to new heights at one of the world's most influential companies. You will engineer and operate enterprise-scale Microsoft Hyper-V virtual infrastructure across global data centres. You will apply depth and breadth of knowledge across multiple domains — hypervisor platforms, storage, networking, clustering, performance engineering, and security compliance — to deploy, optimize, and maintain virtual infrastructure that supports tens of thousands of workloads across multiple regions. This role sits within the Compute Engineering team, which owns the full lifecycle of virtual infrastructure: hypervisor deployment and upgrade, cluster operations, performance engineering, storage optimization, workload management, and compliance remediation. A separate hardware engineering function handles server certification, firmware lifecycle management, and hardware lab validation. You will collaborate closely with hardware engineering — evaluating hardware BOMs for performance characteristics specific to Hyper-V and providing technical feedback — but your primary focus is the virtualization platform layer and above. You will work across Windows Server and Hyper-V clustering, storage subsystems, and automation tooling — maintaining and extending a custom .NET-based workload management platform as needed. You will provide stewardship to other engineers through technical guidance, peer review, and design documentation. Experience with Hyper-V at enterprise scale is a strong differentiator. Job Responsibilities Architecture & Systems Design * Design and maintain Hyper-V cluster architectures including failover clustering, live migration, storage configuration, and network topology across global data centre pools. * Evaluate hardware BOMs proposed by hardware engineering for Hyper-V performance characteristics — processor/memory ratios, storage throughput, network bandwidth, and overcommit suitability — and provide technical feedback to inform procurement decisions. * Audit performance of complex virtual infrastructure across the full stack — compute, storage, networking, and hypervisor layers — and maintain architecture artifacts (high-level design documents, decision records, diagrams) using firmwide tooling. * Develop and document reference architectures and best practices for Hyper-V cluster deployment, storage configuration, and workload placement. Coding * Create and maintain automation for virtual infrastructure lifecycle management — provisioning, configuration, patching, compliance enforcement, and decommissioning of Hyper-V workloads — using PowerShell, WMI, and the team's .NET-based workload management platform. * Write PowerShell scripts for host configuration management, inventory collection, cluster operations, and firmware deployment across the Hyper-V fleet. * Maintain and extend the existing C# / .NET 8 workload management platform as needed — including the server-side orchestration API, distributed worker engine, and Windows client agent components. * Provide stewardship to other engineers in support of quality delivery — peer reviewing automation scripts, infrastructure designs, and technical documentation. Automation & Continuous Delivery * Advocate for and implement infrastructure automation, identifying opportunities to automate, combine, or simplify operational processes with a focus on scalability versus resource use. * Develop and maintain automation for Hyper-V host configuration, cluster provisioning, rolling upgrades, and compliance enforcement using PowerShell DSC, scripts, and the team's workload management platform. * Support and evolve CI/CD pipelines for infrastructure automation tooling, including multi-environment deployment and automated testing. Distributed Systems Design & Development * Plan and execute Hyper-V cluster upgrades, Windows Server rolling upgrades, and hypervisor patch rollouts across production environments with zero or minimal downtime. * Troubleshoot production issues across the virtual infrastructure stack — hypervisor, clustering, storage, and networking layers — using structured logging, event tracing, performance counters, and vendor diagnostic tools. * Consider all risks, potential environmental impacts, and FinOps implications when designing and implementing infrastructure changes. Required Qualifications, Capabilities, and Skills * 5+ years of hands-on experience in infrastructure engineering with demonstrated depth and breadth of knowledge across multiple domains (virtualization, storage, networking, Windows Server administration). * Strong expertise in Microsoft Hyper-V at enterprise scale: failover clustering, live migration, storage spaces / S2D, virtual networking (Hyper-V virtual switch, SET), and Windows Server administration. * Strong proficiency in PowerShell scripting for infrastructure automation, host configuration management, WMI-based inventory collection, and operational tooling. * Demonstrated ability to audit performance of complex infrastructure architecture across the full stack and to maintain architecture artifacts (design documents, decision records, diagrams). * Experience with storage performance analysis and optimization in virtualized environments — benchmarking, capacity planning, and storage policy design. * Ability to evaluate hardware BOMs for Hyper-V suitability — assessing processor/memory ratios, storage I/O characteristics, network throughput, and overcommit profiles. * Experience with infrastructure automation and configuration management tools (DSC, SCCM, Ansible, or equivalent) at data centre scale. * Experience advocating for and implementing infrastructure automation — CI/CD pipelines, operational process improvement, and configuration-as-code — with a focus on scalability versus resource use. * Track record of providing stewardship to other engineers through technical guidance, design review, and documentation. * Degree in Computer Science, Computer Engineering, Information Systems, or a related technical field
