Hardware Developer 4

Job Description

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 UPS-generator 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.
