Job Title: Subject Matter Expert (SME) – Electrical Power Systems Design (AI Data Centers)

Location:
Mumbai Department: : AI Datacenter Design Engineering & Technical Architecture Team Reports To: Head of Design Position Overview: We are seeking an industry-leading Subject Matter Expert (SME) – Electrical Power Systems Design to serve as the ultimate authority on power topology, electrical architecture, and high-density distribution for our next-generation AI data center portfolio. You will define the global electrical standards, lead short-circuit and harmonic studies, evaluate medium/low voltage topologies, and design fault-tolerant power paths. This role is responsible for ensuring our power infrastructure reliably delivers continuous, ultra-high-density power to support 100 kW to 150 kW+ per rack GPU clusters while maintaining maximum energy efficiency and system availability.

Key Responsibilities
1. High-Density Power Architecture & Innovation Ultra-High Density Distribution: Architect and standardize power delivery models from grid connection down to the rack—including high-amperage busways, power distribution units (PDUs), and whip routing for 100 kW to 150 kW+ per rack GPU deployments (e.g., NVIDIA H100/B200/GB200 architectures). UPS & Energy Storage Topology: Design next-generation uninterruptible power supply (UPS) configurations (distributed, block redundant, or static transfer switch topologies) utilizing lithium-ion, BESS, or flywheel energy storage systems. Medium/Low Voltage Substation Design: Establish specifications for high-voltage grid substations, MV/LV transformers, switchgear, automatic transfer switches (ATS), and localized backup generator plants (diesel/gas/hydrogen). 2. System Modeling, Reliability & Compliance Electrical Power Studies: Lead detailed power system modeling, including short-circuit analysis, arc flash hazard assessments, selective coordination, dynamic load flow, and harmonic distortion mitigation.



Concurrent Maintainability: Ensure all power designs comply with Tier III/Tier IV continuous availability standards, enabling maintenance on any electrical component without taking AI workloads offline. Code & Efficiency Compliance: Enforce compliance with IEEE, IEC, NEC, and local utility regulations while optimizing electrical PUE (Power Usage Effectiveness) and power factor correction. 3. Peer Review, OEM Benchmarking & Operational Escalation Design Validation & Auditing: Conduct deep-dive technical reviews of electrical drawings, single-line diagrams (SLDs), and equipment specifications produced by third-party MEP design consultants. Vendor Benchmarking & R&D;: Direct technical relationships with top-tier electrical OEMs (Schneider, Eaton, Vertiv, Siemens, ABB) to customize high-density power equipment and evaluate emerging solid-state power components. Root-Cause Failure Analysis: Act as the primary technical authority for investigating electrical faults, breaker trips, power quality anomalies, or UPS transfer failures during commissioning or live operations. Qualifications &

Requirements:

Experience:
12–15+ years in data center electrical engineering, with at least 5+ years dedicated to hyperscale or high-density facility power architecture. Domain Mastery: Recognized technical authority in high-density power distribution, MV/LV switchgear, block-redundant UPS topologies, generator synchronizing, and harmonic analysis. AI Density Focus: Proven track record designing and certifying electrical power paths capable of supplying 100 kW to 150 kW+ rack densities.

Education:
Master’s or Bachelor’s degree in Electrical Engineering (Skilled Engineer / PE or Chartered status required). Software Mastery: Advanced proficiency in electrical analysis tools (ETAP, SKM PowerTools, EasyPower, Matlab/Simulink). Key

Skills:
Single Line Diagram (SLD) optimization, short-circuit/arc-flash calculation, PUE optimization, Tier classification compliance, and OEM vendor oversight.
