About Qutwo
QuTwo is a Finnish AI company building sovereign AI solutions for Europe. Our platform, QuTwo OS, orchestrates workloads across classical systems, AI accelerators, and emerging quantum hardware — giving enterprises high-performance AI on infrastructure they control.
We are looking for Senior Infrastructure Architect who is a hands-on builder to design, deploy, and run the GPU infrastructure behind our AI platform - someone who has actually racked the servers, cabled the fabric, brought the cluster online, and locked it down
What you will do
Plan and execute GPU data center build-outs end to end: rack and power design, high-density cooling, cabling, and physical deployment of GPU servers and networking.
Design and stand up high-performance compute fabrics (InfiniBand / RoCE), storage, and out-of-band management for large GPU clusters.
Own capacity, power, and cooling planning together with colocation partners and site operators.
Build the software layer that makes the metal usable: provisioning, firmware and driver lifecycle, monitoring, and cluster scheduling.
Bake security in from day one: physical access controls, network segmentation, hardened baselines, key and secrets management, tamper-evident logging.
Ensure our infrastructure meets the security and compliance requirements our customers demand — including EU data residency and sovereignty expectations, ISO 27001-aligned controls, and customer security audits.
Provide operational support and troubleshooting.
What we are looking for
Proven, hands-on experience setting up GPU or HPC data center environments — you have physically built and commissioned clusters, not just operated them.
Strong grasp of data center fundamentals: power distribution, UPS, cooling (air and liquid), rack density, and site selection trade-offs.
Solid networking skills, including high-speed interconnects (InfiniBand andEthernet) and secure network design.
Real understanding of security requirements for critical infrastructure: physical security, access management, supply-chain integrity, and frameworks such as ISO 27001, SOC 2, or Finland’s Katakri criteria.
Comfort with Linux and automation — you automate what you would otherwise repeat.
A doer’s temperament: you take ambiguous goals, break them into concrete steps, and deliver without waiting to be told twice.
Fluent English; Finnish is a plus. Willingness to travel occasionally.
Nice to have
Experience with NVIDIA DGX/HGX-class systems, liquid-cooled deployments, or multi-megawatt sites.
Background in environments with elevated security requirements (finance, government, defense, or critical infrastructure) or eligibility for security clearance.
Experience negotiating with colocation providers, utilities, or hardware vendors.
