xAI is seeking a Design Engineer to join the High Power Engineering team supporting AI training campus infrastructure. You will design, build, operate, and maintain electrical systems for data centers, working with a small on-site team to scale high-capacity power systems driven by compute demand.
Key responsibilities include producing and maintaining single-line diagrams, three-line diagrams, panel schedules, cable schedules, conduit and raceway layouts, grounding plans, and equipment elevations. You will perform load calculations, voltage drop analysis, cable ampacity and derating, conduit fill, and pull-tension analysis for long underground runs. The role requires sizing MV/LV transformers, switchgear, busway, and feeders while specifying impedance, BIL, temperature rise, and short-time ratings.
You will write equipment specifications and technical bid evaluations for ring-main units, transformers, switchgear, busway, and PDUs. Supply model inputs to protection and power-system studies, resolve field RFIs, issue design changes during construction, and maintain organized design and asset documentation. Compliance with NFPA 70, 70B, 70E, NESC, and IEEE standards is essential.
Required qualifications: Bachelor's degree in electrical engineering, computer engineering, physics, or related discipline; 3+ years of electrical design experience in data center, industrial, or utility facilities.
