Job Description
About Nebul
At Nebul, we’re building Europe’s sovereign AI cloud — trusted, secure, high-performance, and purpose-built as a European alternative to the American hyperscalers.
Our NeoCloud platform is built on Nebul-owned infrastructure and best-of-breed open-source technologies, giving us control from the hardware layer through to the customer-facing cloud services.
What You’ll Be Doing
As a DevOps Engineer, you’ll help build Nexus, Nebul’s orchestration and management platform.
Nexus connects our underlying infrastructure — including compute, GPU capacity, storage, networking, and datacenter services — to the customer-facing Cloud Services and AI teams.
Your primary focus will be developing scalable platform services, APIs, controllers, and automation in Go. Nexus enables the automated delivery of:
- S3 and block storage
- Kubernetes clusters
- Firewalls and network services
This is an API-first and automation-only platform. Customer-facing teams will consume infrastructure exclusively through Nexus APIs and platform components.
Key Responsibilities
- Build scalable platform services, APIs, controllers, and automation in Go.
- Design the foundational architecture of Nexus.
- Create abstractions over Kubernetes, storage, compute, networking, and security services.
- Automate the provisioning and lifecycle management of Kubernetes clusters, S3 storage, block storage, and firewalls.
- Integrate Nexus with the APIs provided by Nebul’s Platform and Infrastructure teams.
- Define clean, versioned APIs for customer-facing engineering teams.
- Implement authentication, authorisation, RBAC, tenant isolation, and policy enforcement.
- Build asynchronous workflows for long-running infrastructure operations.
- Ensure all services are observable, resilient, secure, and production-ready.
- Evaluate and integrate open-source components where they accelerate development.
- Take ownership of solutions from architecture through production.

- Knowledge of Infrastructure as Code, CI/CD, and GitOps.
- Experience with asynchronous and event-driven architectures.
- Understanding of cloud services such as compute, networking, object storage, and block storage.
- Experience with authentication, authorisation, RBAC, and multi-tenancy.
- An ownership mindset and the ability to turn infrastructure capabilities into scalable platform services.
Bonus Points If You Have
- Experience building cloud control planes, internal developer platforms, or XaaS products.
- Knowledge of OpenStack or private cloud platforms.
- Experience with Kubernetes operators and Custom Resource Definitions.
- Familiarity with S3-compatible storage, VAST Data, or Ceph.
- Experience with FortiGate, firewalls, networking automation, or software-defined networking.
- Knowledge of workflow engines, policy engines such as OPA, or service catalogues.
- Experience with NVIDIA GPU infrastructure or AI platforms.
