Workplace Type:

The OUX Infra Engineer owns the infrastructure foundation that the Octave Unified Experience (OUX) platform runs on. This role is responsible for designing, deploying, and operating the Kubernetes-based infrastructure, database layer, Microsoft Fabric integration points, and the Refold MCP service that together enable Platform Studio and all OUX shell applications to function reliably at scale, across multi-tenant customer environments. This is a platform infrastructure role with a product engineering sensibility — the infrastructure you build directly determines what developers and customers can do on the platform.

• Design, deploy, and operate the Kubernetes infrastructure underpinning the OUX platform — cluster configuration, namespace strategy, resource management, autoscaling, and multi-tenancy isolation
• Own the PostgreSQL database layer for the OUX platform — schema design, provisioning, backup and recovery, performance tuning, and migration strategy for the ontology tool and Platform Studio backend services
• Build and maintain the Microsoft Fabric integration infrastructure — service principal configuration, workspace provisioning, lakehouse connectivity, and Fabric API authentication patterns for the platform's data pipeline triggers
• Deploy and operate Refold as the platform's MCP tool configuration service — maintaining the Refold API surface, its integration with the agentic framework, and the infrastructure reliability guarantees the MCP Designer tool depends on
• Design and implement the tenant provisioning infrastructure — automated onboarding of new customer tenants, namespace isolation, credential management, and per-tenant resource quotas
• Own infrastructure security posture: network policies, secrets management (Azure Key Vault), certificate lifecycle, and the ingress/reverse proxy layer
• Build and maintain CI/CD pipelines for infrastructure-as-code (Bicep, Terraform, or Helm) and application deployment across environments
• Instrument the infrastructure layer with observability tooling — metrics, logs, distributed tracing, and cost-per-tenant dashboards feeding the platform's commercial reporting
• Collaborate with the OUX UI Engineer on security architecture — AuthN/AuthZ integration (Ory, Azure AD), CORS policy, and penetration testing remediation

• 5+ years in platform or infrastructure engineering, with hands-on production Kubernetes experience (AKS strongly preferred)
• Strong proficiency with PostgreSQL — schema design, performance tuning, HA configuration, and operational management
• Hands-on experience with Azure infrastructure services: AKS, Azure Key Vault, Azure Container Registry, Azure Monitor, and Azure networking
• Experience with Microsoft Fabric administration — workspace management, capacity configuration, service principal access, and API-based provisioning
• Proficiency with infrastructure-as-code tools (Bicep, Terraform, or Pulumi) and Git Ops practices
• Experience designing and operating multi-tenant SaaS infrastructure — namespace isolation, resource quotas, and tenant lifecycle management
• Strong understanding of Kubernetes security primitives — RBAC, network policies, pod security standards, and secrets management
• Experience with CI/CD pipeline design and operation (Azure Dev Ops, Git Hub Actions, or comparable)
• Solid understanding of OAuth2/OIDC and enterprise identity integration patterns

• Experience with Refold or comparable MCP service infrastructure
• Familiarity with Ory (Hydra, Kratos) for identity and access management
• Background in industrial or capital project software infrastructure environments
• Experie…
