Nebul; Leiden; On-site; EUR 75,000 - 110,000; Full time

Job summary

Nebul in Leiden is building Europe's sovereign AI cloud. We are shipping Nexus, a Kubernetes-based orchestration and management platform that connects our compute, storage, networking, and datacenter services to customer-facing Cloud Services and AI teams.

As a DevOps Engineer, you will design scalable platform services and APIs in Go, automate cluster provisioning, define clean APIs for customers, and ensure observable, secure, production-ready systems.

Qualifications

• Strong software engineering experience in Go.
• Hands-on with Kubernetes and cloud-native platforms.
• Experience building APIs, controllers, operators, or distributed backend services.
• 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.
• Ownership mindset and ability to turn infrastructure capabilities into scalable platform services.

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.

Job description

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
• 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.

What Your Day Will Not Look Like

• Manually provisioning customer infrastructure.
• Operating Kubernetes clusters through repetitive command-line work.
• Spending most of your time handling support tickets.
• Building frontend applications.
• Developing isolated services without considering the wider platform architecture.

What You Bring

• Strong software engineering experience in Go.
• Hands‑on experience with Kubernetes and cloud-native platforms.
• Experience building APIs, controllers, operators, or distributed backend services.
• 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.

Eligibility & Application Information

We welcome non‑native Dutch speakers to apply. However, to be eligible, you must:

• Have a valid work permit for the Netherlands. We offer visa sponsorship, but you must already be living and working in the Netherlands.
• Reside in the Netherlands and be able to travel to our office in Leiden.
• Be fluent in English. Dutch is not required.
