Participate in job walks, project estimating, and customer technical discussions
Serve as a technical resource and trainer for developing relay technicians

Travel Requirements:
Work is performed at customer sites throughout the assigned region. Regular regional travel is required, with opportunities for extended assignments outside the region as needed.

Solid understanding of utility safety rules, energized work practices, and lockout/tagout procedures
Ability to interpret:
