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 electrical feasibility before commercial commitment. A site or agreement is only as good as its ability to support the power capacity and distribution infrastructure required to run it. You'll lead electrical due diligence, utility interconnection analysis, and equipment feasibility review to inform Go / No-Go decisions before deals close. Keep electrical design decisions ahead of development. Coordinate with Site Selection, Development, Engineering, and Delivery so power distribution topology, redundancy strategy, and equipment assumptions 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 electrical engineering review across every AI infrastructure acquisition in the Americas. About the Role As an Electrical Engineer, you'll provide the technical electrical 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 power distribution, utility interconnection, 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 electrical infrastructure while helping build the systems that make every future evaluation faster, more predictable, and more scalable. What You'll Own Lead electrical engineering evaluation of prospective sites, colocation capacity, and build-to-suit opportunities. Own technical assumptions for power distribution topology, capacity, and equipment strategy feeding the pre-construction risk register. Assess utility interconnection, on-site generation, and redundancy strategies (N, N+1, 2N) against site conditions and load requirements. Recommend Go / No-Go input on electrical feasibility as projects advance through key development milestones. Deliver technically validated electrical scope to the Delivery organization with complete documentation and minimized risk. Technical Due Diligence & Feasibility Lead electrical due diligence on prospective sites, existing facilities, and colocation capacity under evaluation. Evaluate utility capacity, interconnection queue position, substation requirements, and on-site generation/UPS strategy against projected IT load. Assess electrical equipment availability, lead times (transformers, switchgear, generators), and vendor constraints that could affect schedule or capex. Ensure electrical assumptions are fully integrated into project budgets, capacity models, and schedules. Design & Equipment Strategy Partner with Engineering to define power distribution topology and redundancy strategy appropriate to each site and deal structure. Evaluate EPMS/BMS controls integration and electrical system commissioning requirements early in the acquisition process. Provide technical input on switchgear, UPS, and generator selection, redundancy strategy, and capex trade-offs across candidate sites. Ensure electrical design intent is preserved as deals move from negotiation into development. Construction Readiness Establish electri
