• Perform foundation designs.
• Perform conductor selection studies, shielding, grounding and induction studies.
• Develop cost estimates and schedules and prepare specifications for the procurement of transmission line materials and construction. 
• Specify transmission line components.
• Model transmission lines in PLS-CADD, determine right of way requirements, calculate conductor sags, and develop transmission line plan and profile drawings. 
• Review vendor submittals.

This role offers a hybrid work arrangement, with the expectation of spending three days a week in the office, giving you the flexibility to work remotely for two days.

Dependent upon your location, this opportunity offers a generous relocation package.
