The ideal candidate has strong power systems fundamentals, experience with medium- and high-voltage equipment, and the ability to collaborate across engineering, construction, and project management teams.

KEY JOB RESPONSIBILITIES*:

• Substation & Power Systems Design
• Develop electrical designs for medium- and high-voltage substations supporting renewable energy projects.
• Prepare one-lines, three-lines, wiring diagrams, grounding plans, protection and control schematics, and equipment layouts.
• Design and specify substation equipment including transformers, breakers, relays, switches, and protection systems.
• Perform basic power system studies as required (load flow, short circuit, grounding, etc.).

Engineering Tools & Documentation

• Produce and review design drawings using AutoCAD and/or MicroStation.
• Prepare technical specifications, design calculations, and engineering documentation.
• Support permitting, utility interconnection, and regulatory submittals.

Cross-Functional Coordination

• Coordinate with civil, structural, protection & controls, and solar engineering teams.
• Support construction teams by responding to RFIs, reviewing submittals, and resolving field issues.
• Interface with utilities, AHJs, and third-party engineers to ensure alignment with interconnection and design standards.

Compliance & Standards

• Ensure designs comply with NEC, NESC, IEEE standards, utility requirements, and project-specific criteria.
• Incorporate safety, constructability, and long-term reliability into all designs.
• Support commissioning and energization activities as needed.
