## Description

We are seeking a Senior AI Data Center Electrical Engineer to lead the electrical power design, implementation, and optimization of high-performance computing (HPC) and AI data centers. This critical role focuses on delivering reliable, scalable, and efficient power infrastructure for next-generation GPU-accelerated systems at massive scale. You will drive projects involving large-scale (100-300 MW) HPC/AI facilities as well as modular data center deployments (1-2MW per MDC) that aggregate into 50-300 MW sites, with deep understanding of NVIDIA Grace Blackwell (GB300) and Vera Rubin (VR200) reference architectures.
What impact you will have

 * Design, specify, and optimize medium-voltage (MV) and low-voltage (LV) electrical distribution systems for hyperscale and modular HPC/AI data centers, including switchboards, overhead busways, circuit breakers, transformers (including ML/VL types), PDUs, RPPs, grounding, and protection systems.
 * Lead power architecture for NVIDIA GB300 (Grace Blackwell) and VR200 (Vera Rubin) Superpod/reference deployments, addressing high-density rack power requirements (e.g., 120-160 kW+ per NVL72 rack), liquid cooling integration, power smoothing, and synchronous load management.
 * Develop and implement Battery Energy Storage Systems (BESS), UPS, generators, and backup power solutions to ensure 99.999% uptime and grid stability for AI/HPC workloads.
 * Architect modular data center solutions (1-2 MW containers/pods) that scale efficiently into larger 50-300 MW+ HPC/AI sites, focusing on rapid deployment, standardization, and interoperability.
 * Perform power system studies (short circuit, arc flash, coordination, load flow, harmonics, grounding) and ensure compliance with NEC, NFPA, IEEE, and other relevant codes/standards.
 * Collaborate with mechanical, structural, and IT teams on MEP (Mechanical, Electrical, Plumbing) integration, including 480V AC and 800V DC architectures, overhead busway distribution, and high-current delivery systems.
 * Create and be able to explain detailed single-line power flow diagrams, providing full specifications, justification for design decisions to both technical and non-technical customers.
 * Support construction, commissioning, and operations phases: review drawings, specifications, and submittals; troubleshoot issues; and optimize for efficiency, capacity planning, and cost.
 * Evaluate and integrate emerging technologies for power density, energy efficiency, and sustainability in AI factories.
 * Mentor junior engineers and contribute to the development of company standards and best practices for data center electrical infrastructure.
