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.

Responsibilities

• 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

Requirements

• 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.

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.
