Substation Design Engineering

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.
