• Administer Windows and/or Linux server environments, virtualisation platforms, storage and associated infrastructure services. • Monitor availability, capacity and performance; investigate alerts and restore service within agreed priority and escalation procedures. • Plan and execute approved patching, configuration changes, hardening and lifecycle maintenance. • Maintain server inventories, configuration records, operating procedures, diagrams and technical runbooks. • Support incident, problem and change management, including root-cause analysis and corrective actions. • Coordinate infrastructure dependencies with network, cloud, backup, cybersecurity, application and database teams. • Support discovery, baseline assessment and transition activities for on-premises and any subsequently approved hosted environment. • Participate in agreed on-call coverage for critical infrastructure incidents.

• Design, build, and maintain the versioned REST and gRPC APIs for bare-metal server lifecycle, MachineType definitions, and cluster CRUD operations. • Develop the asynchronous workflows that drive server enrollment, inspection, OS provisioning, and cluster bring-up, exposing durable status to callers. • Implement and maintain the consoles and interfaces that visualize hardware inventory, provisioning progress, and cluster health. • Design the error-handling models, idempotency guarantees, and reconciliation loops necessary to manage long-running provisioning operations reliably.

Role Description - Administer Windows and/or Linux server environments, virtualisation platforms, storage and associated infrastructure services. - Monitor availability, capacity and performance; investigate alerts and restore service within agreed priority and escalation procedures. - Plan and execute approved patching, configuration changes, hardening and lifecycle maintenance. - Maintain server inventories, configuration records, operating procedures, diagrams and technical runbooks. - Support incident, problem and change management, including root-cause analysis and corrective actions. - Coordinate infrastructure dependencies with network, cloud, backup, cybersecurity, application and database teams. - Support discovery, baseline assessment and transition activities for on-premises and any subsequently approved hosted environment. - Participate in agreed on-call coverage for critical infrastructure incidents. Qualifications - Minimum 6 years of relevant infrastructure and server administration experience. - Strong hands-on experience with Windows Server and/or enterprise Linux, Active Directory and virtualisation technologies. - Practical knowledge of monitoring, patch management, storage, capacity planning and security hardening. - VCP, MCSE/Microsoft role-based certification, RHCSA or Server+ preferred. - Ability to produce clear technical documentation and work within controlled change processes. - Experience operating hybrid on-premises and cloud environments.

Role Description We are looking for an experienced Full-Stack Software Engineer to design and implement the Infrastructure Services that power our GPU-as-a-Service platform. You will build the control plane that turns high-level API calls into real infrastructure actions — enrolling bare-metal servers, provisioning them, and assembling them into multi-tenant Kubernetes clusters on high-performance hardware. You will own the full lifecycle of the infrastructure-level services—from the Server and MachineType APIs down to the provisioning workflows and reconciliation loops that keep the platform's view of hardware consistent with physical reality. Key Responsibilities - Infrastructure API Design: Design, build, and maintain the versioned REST and gRPC APIs for bare-metal server lifecycle, MachineType definitions, and cluster CRUD operations. - Provisioning & Workflow Development: Develop the asynchronous workflows that drive server enrollment, inspection, OS provisioning, and cluster bring-up, exposing durable status to callers. - Full-Stack Implementation: Implement and maintain the consoles and interfaces that visualize hardware inventory, provisioning progress, and cluster health. - System Reliability: Design the error-handling models, idempotency guarantees, and reconciliation loops necessary to manage long-running provisioning operations reliably. Qualifications - API Development: Strong experience designing RESTful APIs or gRPC services. You understand API versioning and gateway patterns. - Language Stack: Proficiency in Go (preferred for backend/Kubernetes ecosystem) and modern TypeScript/React (for the Console). - Kubernetes Knowledge: Deep understanding of Kubernetes primitives and controller/reconciler patterns. You will be interacting with systems like k0rdent, Metal3, and Cluster API to translate high-level API calls into infrastructure actions. - Bare-Metal Provisioning: Hands-on experience with bare-metal provisioning flows — BMC/Redfish, PXE/iPXE, image management, and hardware inspection. - Asynchronous Systems: Experience building workflow-driven or event-driven systems (e.g., Temporal) where operations are long-running and state must remain consistent across retries and failures. Preferred Qualifications - State Reconciliation: Experience building informers or reconciliation bridges that keep an external datastore consistent with Kubernetes resource state. - Multi-Tenancy: Experience building platforms where strict data and network isolation between tenants is required. - Infrastructure-as-Code: Familiarity with Terraform/OpenTofu and GitOps-driven configuration (ArgoCD or Flux). - Hardware Domain: Familiarity with GPU server hardware, DPUs/NICs, and high-performance datacenter fabrics. Benefits - Work with an established Silicon Valley leader in the cloud infrastructure industry; - Work with exceptionally passionate, talented and engaging colleagues, helping Fortune 500 and Global 2000 customers implement next-generation cloud technologies; - Be a part of cutting-edge, open-source innovation; - Thrive in the high-energy environment of a young company where openness, collaboration, risk-taking, and continuous growth are valued; - Professional development and training; - Attend conferences and working groups; - Company outings, happy hours, hackathons, and tech talks; - Receive a competitive compensation package with a strong benefits plan.
