Coordinate closely with Protection & Control, SCADA, Station Communications, Civil/Structural, and Transmission Line engineering to ensure an integrated, constructible design; assess how design changes in one discipline affect physical layout and drive the team toward the best overall solution.

Lead or assist with engineering studies, site evaluations, constructability reviews, and technical design assessments.

Prepare and oversee project deliverables: engineered drawings, design calculations, technical reports, material take-offs, project correspondence, and construction support documentation.

Perform Quality Control reviews of physical design deliverables across small, medium, and larger projects; mentor junior engineers on QA/QC practices.

Lead proposal development support - scope definition, drawing counts, manhour estimates, and technical input - for substation physical engineering efforts.

Drive development and continuous improvement of physical design processes, standards, and best practices to improve project execution efficiency.

Maintain accurate, well-organized project records, calculations, and design files.
