Mechanical Engineer- Data Centers

Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure. Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI. Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D. The Infrastructure Acquisition Group The Infrastructure Acquisition Group secures the land, power, and data center capacity that enables the Nebius AI Cloud. We identify where Nebius should grow next, structure the commercial agreements that make that growth possible, and partner across engineering, energy, finance, legal, and development to bring new AI infrastructure online. We're a small, founding team building this function from the ground up across the Americas, leading the acquisition of colocation, build-to-suit, powered land, and other strategic infrastructure opportunities as one of the world's fastest-growing AI cloud platforms scales. Examples of Problems We're Solving Validate technical feasibility before commercial commitment. A site or agreement is only as good as its ability to support the mechanical infrastructure required to run it. You'll lead mechanical due diligence, cooling capacity analysis, and equipment feasibility review to inform Go / No-Go decisions before deals close. Keep mechanical design decisions ahead of development. Coordinate with Site Selection, Development, Engineering, and Delivery so cooling topology, capacity assumptions, and equipment strategy are validated early enough to protect schedule and budget once construction begins. Build a repeatable technical evaluation program. Help establish the standards, design criteria, and technical readiness gates that will support mechanical engineering review across every AI infrastructure acquisition in the Americas.

As a Mechanical Engineer, you'll provide the technical mechanical engineering perspective across the acquisition and development lifecycle — from initial site and deal evaluation through construction readiness. Working within the Infrastructure Acquisition Group, you'll partner with Site Selection, Technical Due Diligence, Development, Energy, Finance, and Delivery to ensure every project's mechanical systems, cooling strategy, and equipment assumptions are technically sound before they move forward This is a build-phase role on a build-phase team. Many of the technical evaluation standards, design criteria, and readiness gates you'll use are still being written — in some cases, you'll help write them. We're looking for someone who can independently assess complex mechanical infrastructure while helping build the systems that make every future evaluation faster, more predictable, and more scalable
