Power Systems Engineer

The Data Center Engineering Analytics and Modeling (DCEAM) organization is seeking a Power Systems Engineer to lead grid to rack electromagnetic transient (EMT) simulations for AI data centers. You will develop detailed MV / LV power system models from the utility source through the IT load to analyze transient performance, harmonic distortion, protection, grounding, and UPSgenerator interactions. These models will be used to ensure power quality, stability, and reliability across all operating modes. You will support projects from site selection and design through commissioning and integrated systems testing (IST), working closely with design, operations, vendor, and utility teams.

Responsibilities

• Develop & Maintain EMT Models : MV sources; transformers (saturation / inrush); grounding; cables; UPS / DRUPS; generators (AVR / governor); STS / ATS; Busway / PDU / RPP; filters / FACTS; VFD-driven HVAC.
• Conduct Dynamic Performance and Transient Studies : Generator-UPS Compatibility; Large block load step (GPU ramp-up) response; Transformer inrush and load transfer; Generator start and transfer sequences; UPS input / output switching and bypass events; Black Start; Frequency Stability; Rotor-Angle Stability; Voltage Stability / Voltage Ride Through.
• Conduct Power Quality Studies : Flicker / Voltage Step Analysis; Harmonic / Resonance scans and filter application; Inrush / Ferroresonance; Converter Limited Fault Behavior; Power Factor Correction.
• Conduct Steady-State Analysis : Load flow / Voltage Drop; Short Circuit / Equipment Evaluation; Protection & Coordination; Arc Flash Hazard Analysis; Grounding Study
• Support generator and UPS vendor coordination for paralleling, synchronization, and control system stability.
• Generate FMU models for multi-domain simulations
• Establish modeling standards, libraries, QA, version control; automate cases, sweeps, and reporting.
• Review vendor black-box models; document assumptions and deliver clear, actionable reports.
• Ensure compliance with internal security, data handling, and licensing policies for tools and models.
• Collaborate with cross-functional teams (mechanical, controls, commissioning, etc.) to ensure electrical system stability under dynamic load profiles.
• Author study reports and technical memos for design review and operational readiness.
