Server Power Architect

Description and Requirements About Our Team We are hiring a senior Data Center Power Architect for Lenovo’s Cloud Service Provider Group (CSP). This role will lead next-generation end-to-end power architecture for hyperscale, cloud, AI/GPU, server, and storage infrastructure—from data center AC distribution through rack and server DC power delivery. What You’ll Do Lead end-to-end power architecture from utility/grid interface to rack and server loads. Define AC infrastructure covering MV/LV distribution, transformers, switchgear, UPS, generators, PDU, busway, protection, grounding, redundancy, and power quality. Define rack/server DC architecture covering PSU/power shelves, 48V/54V/12V, DC busbars, BBU/capacitor shelves, DC-DC/POL, and emerging HVDC. Develop architectures for 100 kW, 200 kW, 500 kW and future MW-class AI racks/pods. Optimize efficiency, density, availability, redundancy, serviceability, scalability, and cost across the complete power chain. Analyze peak/dynamic GPU loads, power excursions, transient response, ride-through, backup power, and energy storage. Develop system/rack power budgets, capacity models, redundancy schemes, and fault-protection strategies. Evaluate centralized vs. distributed power and emerging AC/DC/HVDC architectures. Lead architecture trade-offs, specification/design reviews, technology evaluation, and validation strategy. Develop next-generation data center and rack power technology roadmaps. Partner with thermal, mechanical, cooling, rack, server, GPU, facilities, and system architecture teams. Engage hyperscale/cloud customers, suppliers, ODM/OEMs, and technology partners. Lead complex system/rack power issue root-cause analysis. Key Architecture Areas AC distribution 400/480Vac and 415/240Vac architectures Transformers, switchgear, UPS, generators, ATS/STS PDU, busway and rack distribution N, N+1, 2N and distributed redundancy Power quality, grounding and protection 48V/54V/12V DC and emerging HVDC PSU and power shelves DC busbars, BBU and capacitor shelves AC/DC and DC/DC conversion Energy storage and ride-through High-density AI/GPU rack power Minimum Qualifications Bachelor’s degree in Electrical Engineering , Power Engineering, Computer Engineering, or related field. 10+ years of data center power, critical power infrastructure, rack/server power, or power electronics experience. Strong expertise in data center AC electrical infrastructure and three-phase power systems. Experience with transformers, switchgear, UPS, generators, PDU, busway, protection, grounding, and redundancy. Working knowledge of rack/server DC architectures including 48V/54V, PSU, power shelves, busbars, BBU, and DC-DC conversion. Strong system-level architecture and technical trade-off capability. Experience developing power specifications, architecture documents, and validation plans. Preferred Qualifications Master’s degree in Electrical /Power Engineering or related field. Hyperscale, cloud, or AI data center experience. Experience with 100 kW+ AI racks and MW-class rack/pod architectures. Knowledge of MV/LV distribution, HVDC, advanced energy storage, and solid-state power conversion. Knowledge of OCP architectures and IEC, UL, and IEEE requirements. Understanding of interactions among power, cooling, thermal, mechanical, compute , networking, and rack infrastructure. Experience engaging directly with hyperscale customers and ecosystem partners. Strong technical leadership, communication, and executive presentation skills.
