  • Create and maintain accurate test reports, as-left settings, and field documentation
  • 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.
• Company vehicle provided for regional work-related travel.
What You Bring
  • 5+ years of hands-on experience in protective relaying for utility substations
  • Demonstrated experience testing medium- to high-voltage (5kV-500kV) protection systems
  • Strong working knowledge of microprocessor-based relays
  • Experience with modern relay test platforms
  • Solid understanding of utility safety rules, energized work practices, and lockout/tagout procedures
  • Ability to interpret:
    • Protection diagrams
    • AC/DC schematics
    • Wiring and logic drawings
  • Valid driver's license; ability to work outdoors, travel, and lift up to 70 lbs
