• High school diploma or GED required; technical school, military electrical training, or Associate's degree a plus.
• 5–8 years of relevant field service experience with LV/MV switchgear, breakers, ATS, generators, or related electrical equipment.
• Working knowledge of electrical safety practices including LOTO and arc-flash risk controls.
• Proven ability to read and interpret schematics, wiring diagrams, and one-line diagrams.
• Hands-on experience performing transformer field testing (insulation resistance, TTR, winding resistance) and oil sampling.
• Ability to write clear field reports and maintain accurate test documentation.
• Valid driver's license with an acceptable motor vehicle record, maintained throughout employment; ability to travel as required, sometimes on short notice.
• Must be at least 21 years of age to be assigned and operate a company-provided service vehicle.
• Must be able and willing to obtain Department of Transportation (DOT) non-CDL qualification, including a current DOT medical card where required for towing test trailers or oil-processing equipment, and comply with applicable DOT regulatory requirements.
• Solid understanding of LV/MV electrical distribution systems, grounding, and protection concepts.
• Proficiency with electrical test equipment and torque tools.
• Ability to troubleshoot common electrical and mechanical issues independently.
• Strong safety compliance and documentation practices.
• Clear communication with crew, customers, and leadership.
• Proficiency with Microsoft Office (Word, Excel) and mobile/field reporting tools.

Nice To Haves

• OSHA 10 or OSHA 30 certification.
• Completion of Forgent Power TQP Level 3.
• Manufacturer/OEM training on switchgear, breakers, ATS, or generator platforms.
• Familiarity with major OEMs (e.g., Eaton, ABB/Hitachi, Siemens, GE, Schneider, Caterpillar, Cummins, Kohler).
• Exposure to protection relay platforms (e.g., SEL, GE/Multilin, Siemens SIPROTEC) and relay configuration software.
• Exposure to control platforms (SEL, ComAp, Woodward) or PLCs.
• Hands-on use of relay test sets (e.g., Omicron, Doble) in a supporting role.
• Experience with load tap changer inspection and oil processing (filtration, dress and fill, regasketing).
• Working knowledge of IEEE C57 series transformer testing practices.

Responsibilities

• Independently perform preventive maintenance and testing on LV and MV switchgear, breakers, ATS, RPPs, and PDUs.
• Execute insulation resistance, continuity, contact resistance, and basic functional testing with minimal supervision.
• Perform breaker removal, inspection, and reinstallation under established procedures.
• Support generator maintenance, load bank testing, and operational checks.
• Independently perform preventive maintenance and field testing on dry-type, cast-coil, pad-mount, unit-substation and liquid-filled transformers up to medium voltage.
• Perform and interpret insulation resistance, transformer turns ratio (TTR), winding resistance, and excitation current tests.
• Perform oil sampling for dissolved gas analysis (DGA), moisture, and dielectric strength; interpret routine lab results and flag exceptions for engineering review.
• Perform de-energized tap changes and verify no-load tap changer operation.
• Inspect and service load tap changer (LTC) mechanisms and controls under established procedures.
• Verify transformer grounding and perform ground resistance testing.
• Verify cooling system operation (fans, oil pumps, RTDs and temperature control circuits) and alarm and trip signaling.
• Support oil processing activities including filtration, dress and fill, and regasketing.
• Troubleshoot common transformer issues including overheating, oil leaks, gauge and alarm faults, and cooling system failures.
• Read and interpret one-line diagrams, schematics, and wiring diagrams to support troubleshooting.
• Troubleshoot common electrical, mechanical, and control issues; escalate complex faults to the Field Service Engineer or Sr. Field Service Engineer.
• Support commissioning activities including pre-energization checks, point-to-point verification, and functional testing.
• Assist with control wiring checks, interlock verification, and basic communication diagnostics.
• Assist with protection relay testing and secondary injection under the direction of a Field Service Engineer or Sr. Field Service Engineer.
• Support verification of relay settings and functional checks of protection and control circuits.
• Comply with all safety requirements including LOTO, arc-flash, energized work restrictions, job hazard analysis, and permits.
• Participate in and contribute to on-site safety briefings and follow safe work practices at all times.
• Ensure work complies with applicable codes and standards (NFPA 70E, OSHA) and customer site-specific requirements.
• Lead portions of job execution and oversee apprentices and Level 2 technicians on assigned tasks.
• Share best practices and provide on-the-job training to less experienced team members.
• Communicate progress and findings clearly to lead technicians, project managers, and customers as needed.
• Document service activities, complete test records, and maintain accurate punch lists and field reports.
• Coordinate with project managers and supply chain on parts and material needs.
