• Perform structural analysis and design of pole, lattice, framed, and guyed structures.
• 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.

We do not sponsor employees for work authorization in the U.S. for this position.

Essential skills and experience:

• This position requires a degree from an ABET-accredited engineering program.
• Related engineering, internship or co-op work experience.
• Proficiency with PLS-CADD and PLS-POLE.
