Principal Electrical Engineer

Crusoe · Data AI · Arvada, CO - US · Manufacturing (MFG)

Crusoe is an AI infrastructure company focused on accelerating energy and intelligence. They are seeking a Principal Electrical Engineer to be the technical authority on power distribution, protection, and switchgear design for their modular integrated electronics buildings and critical power infrastructure. The role involves defining engineering standards, architecting robust power systems, solving complex protection coordination challenges, and leading the technical direction of the electrical engineering team, with a strong emphasis on regulatory compliance (NEC, IEEE, UL).

What you'd actually do

  1. Serve as the reigning SME for power distribution and switchgear design (low and medium voltage). Lead high-level system architecture to ensure reliability and selectivity for modular data centers and power distribution centers.
  2. Act as the final decision-maker on complex code interpretations, ensuring strict compliance with NEC (NFPA 70), UL 1558/1670/891/508A, and IEEE standards.
  3. Perform and oversee critical power system studies, including Short Circuit, Coordination, Arc Flash, and Load Flow analysis.
  4. Design and validate complex protection schemes, selecting and configuring protective relays (SEL, ABB, etc.) to ensure optimal system reliability.
  5. Conduct deep-dive technical reviews of designs produced by the engineering team, serving as the final quality gate before fabrication.

Skills

Required
