Seasonal Relay Tester Jobs (NOW HIRING)

Hunt Utility Services is a privately held company providing management and support services for Sharyland Utilities, L.L.C., a Texas-based electric transmission utility.  We are committed to providing safe, reliable, and efficient transmission and substation services, ensuring operational excellence, and investing to support the infrastructure needs of the Electric Reliability Council of Texas grid.

Position Summary

Reporting to the District Manager, the Field Engineer leads protection, control, commissioning, and diagnostic operations across HUS transmission facilities, with co-equal responsibility for conventional AC substation systems and the Sharyland HVDC converter station. Working with general supervision, the Staff Field Engineer independently plans and executes relay testing, equipment commissioning, fault diagnosis, and NERC compliance documentation. HVDC and FACTS system experience carries equal weight with conventional P&C - HUS is actively evaluating insourcing of HVDC maintenance, and this role is positioned as the primary internal technical resource for that initiative. 

Responsibilities

• Execute testing, calibration, and commissioning for SEL and GE protection platforms, SEL RTAC SCADA devices, and DFR equipment; analyze relay event reports and coordinate protection schemes with transmission operations.
• Perform NETA-compliant acceptance and maintenance testing on power transformers, circuit breakers, disconnect switches, and associated metering and control equipment.
• Conduct CT ratio and polarity testing, panel wiring verification, and control circuit continuity checks in accordance with NERC PRC-005 maintenance intervals.
• Participate in planned maintenance at the Sharyland HVDC converter station (Hitachi MACH 2/3 platform), including thyristor valve inspection, protection system testing, and control system verification.
• Serve as the asset-owner technical representative during OEM field service windows; provide independent scope oversight and documentation of Hitachi maintenance activities.
• Develop working proficiency with HVDC equipment to support HUS insourcing feasibility evaluation; document OEM procedures and internal capability benchmarks.
• Commission new and modified substation equipment, including relay panels, control buildings, and protection and communications infrastructure.
• Diagnose complex protection system faults, determine root cause, and direct corrective actions.
• Coordinate maintenance scheduling under ERCOT seasonal restriction windows; plan and execute outage work within approved windows.
• Maintain NERC PRC-005 maintenance records and author PRC-004 relay event reports for PUCT/ERCOT audit readiness.
• Author field test procedures and maintain compliance documentation packages.
• Other duties as assigned.

Required Skills

• Proficiency with protective relay test equipment (OMICRON, Doble F6150, or equivalent).
• Ability to read and interpret engineering drawings, protection one-lines, and relay settings files.
• Relay configuration and event analysis software experience (SEL AcSELerator, SEL-5030, or equivalent).
• Excellent field documentation, organizational, and communication skills.
• Self-directed, professionally mature, and capable of working independently in field environments.
• Valid Texas driver's license and clean driving record.
• Proficiency with Microsoft 365 applications.

Required Experience

• Bachelor's degree in electrical engineering from an ABET-accredited program or a program with recognized equivalency.
• 7+ years of progressive field experience in protection, control, and relay systems commissioning, testing, and maintenance.
• Demonstrated proficiency with NETA testing standards and protective relay platforms.
• FE/EIT registration preferred.
• HVDC system experience preferred (Hitachi, ABB, Siemens, or equivalent converter station platform); FACTS equipment (SVC, STATCOM) commissioning or maintenance experience is a strong differentiator.

Working Conditions

• Field-based position assigned to transmission districts; not eligible for remote or hybrid work arrangements.
• Works in outdoor substation and HVDC station environments; in proximity to high-voltage energized equipment.
• Participates in the district on-call rotation.
• Maintenance occasionally scheduled on nights and weekends.
