It governs GPU telemetry, cooling, power and grid interaction as one integrated layer, so that every Firmus site can be optimised and monitored as a single system.  AI FactoryOS Operations runs that platform in production and owns the 24/7 reliability of AI FactoryOS, Firmus AI Cloud and the platforms built on them, together with the service levels the estate is measured against.  The remit is an engineering one. The function builds the guarded automation, remediation and operational tooling that turn manual response into a software-defined capability, and builds and operates the shared services the estate's own operation depends on. The function works closely with the engineering teams that build the platform, supplying the production evidence that shapes what they fix and what they build next.    Role Summary   Firmus runs large-scale, state-of-the-art AI infrastructure built on the latest generation of GPU rack-scale systems and operated as one estate to power the next generation of AI innovation. The Platform Reliability Engineer is part of the team that operates the platform services Firmus AI Cloud runs on in production: the GPU compute fleet, exabyte-scale storage, the multi-tenant control and management plane, and the virtualisation and shared services that host it. Together, these are the foundation every customer workload depends on. This is a hands-on site reliability engineering role that works across the stack, from Linux and Kubernetes to storage, virtualisation and the compute fleet. The team runs each service to a declared service level, measures reliability against it, and treats operations as a software problem, engineering repetitive manual work out of the system rather than absorbing it. The role picks up incidents escalated from first response, owns each one through to resolution, and works across teams and vendors to restore service, bringing in specialist engineers when a fault needs deeper investigation. Automation is a first-class part of the role: faults are diagnosed using the observability stack, post-incident reviews feed fixes back into the platform, and every resolved fault is a candidate for a runbook or an automated fix.   Key Responsibilities <ul> <li>Triage, diagnose and resolve incidents across the stack, including Kubernetes clusters and workloads, storage, virtualisation, network connectivity and the underlying Linux hosts, owning each incident from escalation through to resolution.</li> <li>Operate the multi-tenant control and management plane that Firmus' AI and infrastructure services depend on, including the tenancy, quota and access controls that support separation between tenant workloads and data.</li> <li>Operate the virtualisation platform that hosts the management plane, and the shared services that run on it, to their declared service levels.</li> <li>Operate Firmus' exabyte-scale distributed and high-performance filesystems and S3-compatible object storage to their declared service levels, handling capacity, performance and availability incidents and escalating to specialist engineers and vendors (for example VAST or WEKA) with clear evidence when further investigation is needed.</li> <li>Operate the GPU compute fleet in production: node health and readiness, GPU and node fault detection and handling, firmware and driver currency to the supported baselines, remediation and return to service, and support for cluster provisioning and validation activities.</li> <li>Reduce toil by converting repeat fixes into runbooks and automated remediation delivered as controlled code, contributing to the team's automation and remediation tooling.</li> <li>Diagnose performance problems across the data path between compute and storage, gathering the evidence needed to resolve them and working with network and storage specialists where required.</li> <li>Deliver change as code through the agreed change process, with peer review, testing, staged rollout where applicable, and a rollback plan.</li> <li>Use the observability stack (for example Grafana, Prometheus, Loki and Tempo) to track service level indicators against their objectives, query metrics, logs and traces, correlate signals across services and diagnose faults, and improve dashboards and alerting so that each alert is actionable and tied to a runbook.</li> <li>Execute the patching cycle and urgent vulnerability remediation across the services the team operates.</li> <li>Manage vendor support cases across the hardware and software portfolio, raising and tracking cases under the relevant support agreements, supplying logs and diagnostic evidence, and following cases through to agreed response and resolution times.</li> <li>Take part in technical recovery during major incidents and in blameless post-incident reviews, feed recurring issues back to the engineering teams as clear requirements, share the follow-the-sun on-call roster, and keep incident tickets, operational procedures and runbooks accurate and current so that others can execute them successfully.</li> </ul>   Skills & Experience  <span
