Sirius Staffing is seeking a Senior/Principal Electrical Power Systems Engineer for a permanent, direct-hire opportunity focused on advanced electrical power architecture for data center and mission-critical applications.

This is a senior-level electrical power engineering and systems-design role responsible for developing complete AC/DC power-system solutions, performing complex power-system analysis, selecting major electrical equipment, and supporting testing and commissioning.

The ideal candidate will bring deep experience in medium- and low-voltage power distribution, power-system studies, protection, equipment sizing, and electrical system architecture. Direct data center experience is highly valuable, but candidates with strong backgrounds in BESS, microgrids, utility power, power conversion, generation, renewable energy, marine power, or other mission-critical electrical systems will also be considered.

• Lead the design and development of complete electrical power-system architectures for mission-critical and data center applications.
• Translate customer and application requirements into technically sound, reliable, and constructible electrical solutions.
• Perform electrical load calculations, system modeling, equipment sizing, and power-system analysis.
• Perform or review studies including:
  • Load flow
  • Short circuit
  • Arc flash
  • Protection coordination
  • Grounding
  • Harmonics
  • Motor starting
  • Transient and dynamic system behavior, as applicable
• Select and specify major electrical equipment including:
  • Transformers
  • Medium- and low-voltage switch gear
  • Circuit protection
  • Relays
  • Inverters and power-conversion equipment
  • Battery Energy Storage Systems (BESS)
  • UPS systems
  • Generators
  • Cabling and distribution equipment
• Develop and review one-line diagrams, electrical layouts, specifications, calculations, and technical documentation.
• Evaluate fault current, system efficiency, thermal loading, equipment capability, power quality, and overall system performance.
• Support the integration of AC and DC power systems, inverter-based resources, energy storage, and distributed generation.
• Collaborate closely with Controls, Mechanical, Product, and Manufacturing Engineering teams to ensure successful system integration.
• Participate in design reviews and provide technical leadership and guidance to engineers, consultants, and project teams.
• Support prototype development, factory testing, site acceptance testing, commissioning, troubleshooting, and root-cause investigations.
• Provide technical recommendations based on study results, equipment limitations, operating requirements, and applicable codes and standards.
• Support customers during system planning, design reviews, equipment selection, and commissioning activities.
• Evaluate emerging technologies related to critical power, energy storage, power conversion, microgrids, and next-generation data center infrastructure.

• Bachelor’s degree in Electrical Engineering.
• 8+ years of electrical power systems design experience.
• Strong knowledge of AC and DC electrical power systems.
• Experience designing medium- and low-voltage power distribution systems.
• Hands-on experience with ETAP, SKM Power Tools, Easy Power, or equivalent power-system analysis software.
• Experience performing or reviewing load-flow, short-circuit, arc-flash, and protection-coordination studies.
• Strong understanding of protective relaying, electrical distribution, grounding, fault current, and equipment coordination.
• Experience with electrical load calculations and major…
