Virtualization Platform Engineer

Nebul is building Europe’s Intelligent Cloud: a sovereign cloud and AI infrastructure platform designed for organisations that require performance, control, security and data sovereignty.

We develop and operate advanced cloud, Kubernetes and GPU infrastructure across Europe. As our platform continues to grow, we are expanding the engineering capabilities behind our virtualization layer.

We are therefore looking for a

Virtualization Platform Engineer

who combines strong Kubernetes and DevOps expertise with deep knowledge of virtualization technologies.

Your Role

As a Senior Virtualization Platform Engineer, you will help design, build and operate the virtualization layer within Nebul’s cloud platform.

Our current environment uses

KubeVirt , while we are developing additional capabilities based on

Cloud Hypervisor . You will work at the intersection of Kubernetes, virtual machines, containers and low-level Linux virtualization.

This is a hands‑on engineering role for a senior DevOps, platform or infrastructure engineer with a strong specialization in virtualization. A deep background in

KVM and QEMU

is equally relevant, provided you understand—or are ready to work extensively with—Kubernetes-based infrastructure.

You will take ownership of complex technical challenges and help define the future architecture of virtualization within Nebul.

What You Will Do

Design, build and operate Kubernetes-based virtualization solutions

Develop, optimize and maintain our KubeVirt environment

Contribute to the development and adoption of Cloud Hypervisor

Work with KVM, QEMU, microVMs and container-based virtualization

Help design and implement confidential-computing capabilities

Evaluate and implement technologies such as Kata Containers

Automate the deployment, configuration and lifecycle management of virtualized workloads

Improve the performance, scalability, reliability and security of our virtualization platform

Troubleshoot complex issues across Kubernetes, Linux, networking, storage and virtualization

Contribute to architectural decisions and the technical virtualization roadmap

Build monitoring, observability and operational tooling for the platform

Establish engineering standards and share specialist knowledge across the organisation

Work closely with our Kubernetes, cloud, infrastructure and security engineers

What We Are Looking For

Significant professional experience in DevOps, platform engineering, infrastructure engineering or systems engineering

Deep technical knowledge of virtualization concepts and technologies

Strong understanding of Kubernetes architecture and operations

Hands‑on experience with KubeVirt, KVM, QEMU or comparable virtualization technologies

Strong Linux systems-engineering and troubleshooting skills

Experience with infrastructure automation and Infrastructure as Code

Good understanding of networking, storage and security within virtualized environments

Experience diagnosing performance, availability and reliability issues at platform level

The ability to take ownership of technically complex projects

A pragmatic engineering mindset and a willingness to build new capabilities from the ground up

Nice to Have

Hands‑on experience with Cloud Hypervisor

Knowledge of confidential computing and hardware‑backed isolation

Experience with microVM technologies

Experience with Kata Containers, Firecracker or similar runtimes

Programming or automation experience in Rust, Go or Python

Familiarity with OpenStack and cloud‑native infrastructure

Experience with high‑performance computing or GPU infrastructure

Knowledge of hardware virtualization, CPU architecture and performance optimization

Experience contributing to open‑source infrastructure projects

What We Offer

A key engineering role in building Europe’s sovereign cloud and AI infrastructure

The opportunity to shape a technically challenging virtualization platform

Significant ownership and influence over technical and architectural decisions

A highly experienced and ambitious engineering environment

Direct collaboration with Nebul’s engineering leadership and infrastructure teams

Competitive compensation

A mobility budget

A performance bonus and equity participation

A hybrid working environment based around our office in Leiden

The opportunity to grow with a rapidly scaling European technology company

Why Nebul

At Nebul, you will help build the technical foundation behind Europe’s Intelligent Cloud.

You will have the opportunity to shape how virtualization is designed and operated across our sovereign cloud platform. From KubeVirt and Cloud Hypervisor to confidential computing, microVMs and Kata Containers, your work will directly influence the performance, security and scalability of our infrastructure.

You will work closely with Nebul’s engineering leadership, platform teams and infrastructure specialists. Your decisions will shape our virtualization architecture, engineering standards and future cloud capabilities.

This is an opportunity to build—not simply maintain—one of the core technical capabilities of an ambitious European technology company.
