Principal Technical Product Owner - AI Cloud & Datacenter Architecture

About Nebul

At Nebul, we’re building Europe’s sovereign AI cloud — trusted, secure, and purpose-built for the next generation of intelligent infrastructure. We are a small, deeply technical team designing and operating cloud and datacenter platforms from the ground up, with a strong focus on security, compliance, and long-term scalability.

Our platform delivers world-class AI and HPC capabilities while abstracting extreme infrastructure complexity through clear architectures, strong automation, and well-defined product roadmaps.

What You’ll Be Doing

As a Technical Product Owner / Architect – Datacenter & Cloud Infrastructure , you own the technical roadmap and architectural direction of Nebul’s AI-ready infrastructure platforms.

You operate at the intersection of product strategy and deep engineering , translating business and platform requirements into concrete technical designs, reference architectures, and execution plans. You are not a proxy PO — you are technically capable of guiding teams, challenging vendors, and making architectural trade-offs.

You define how our infrastructure evolves across datacenter design, hyperscaler-aligned cloud patterns, Kubernetes-based platforms, and high-performance AI workloads . You work closely with platform engineers, operations, and vendors to ensure Nebul’s infrastructure is scalable, secure, and future-proof.

This role requires hands-on technical understanding: you must be able to lead discussions on cloud architecture, networking, power design, Kubernetes, and AI infrastructure , and steer delivery with confidence.

Key Responsibilities

• Own and maintain the technical roadmap for Nebul’s datacenter and cloud infrastructure platforms.
• Define and evolve reference architectures for AI- and HPC-optimized environments.
• Lead architectural decisions across:
• High-performance compute (GPU-based platforms)
• Networking (Ethernet / InfiniBand)
• Power, cooling, and datacenter scalability
• Kubernetes-based cloud platforms
• Translate strategic goals into concrete technical epics, priorities, and execution plans .
• Guide engineering and operations teams with clear architectural direction and technical context.
• Drive procurement strategy and vendor alignment with partners such as NVIDIA and Mellanox.
• Ensure infrastructure designs align with security, compliance, and sovereign cloud requirements.
• Balance long-term platform vision with short-term delivery and operational realities.

What Your Day Will Not Look Like

• Writing user stories without understanding the underlying technology.
• Managing backlogs without architectural ownership.
• Acting as a communication layer instead of a technical decision-maker.
• Delegating all technical depth to engineers or vendors.
• Working disconnected from real infrastructure constraints.

What You Bring

• 5+ years of experience in datacenter, cloud, or infrastructure architecture .
• Strong hands-on knowledge of:
• Hyperscaler cloud concepts and design patterns
• Kubernetes and cloud-native platforms
• High-performance networking and compute
• Proven ability to own and steer a technical roadmap end-to-end.
• Experience translating complex infrastructure challenges into scalable, actionable designs.
• Confidence engaging with senior engineers, architects, and vendors on deep technical topics.
• Structured, analytical mindset with strong communication skills.

Bonus Points If You Have

• Deep experience designing AI/HPC datacenters .
• Knowledge of OpenStack and infrastructure automation tooling.
• Experience with lifecycle management of large-scale infrastructure (power, cooling, network growth).
• Background working with cloud or infrastructure providers at scale.
• Experience bridging product management and hands-on architecture roles.

Eligibility & Application Information

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

• Have a valid EU work permit (no sponsorship available).
• Reside in the Netherlands and be able to commute to the office near The Hague.
• Be fluent in English (Dutch is not required).
