Server Power Architect

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

• 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.
