Substation Design Engineer

The Substation Design Engineer is responsible for the electrical design and engineering of substations supporting utility‑scale solar and renewable energy projects. This role supports projects from early conceptual design through issued‑for‑construction (IFC) drawings, ensuring compliance with applicable codes, utility standards, and project requirements. 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.

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

• 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.

• 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.
