Field Service Engineer

Aurora Energy Services is hiring Field Service Engineers to test, energize and start up low- and medium-voltage switchboards, switch gear and power transformers on utility-scale solar, BESS, substation and data center projects. You will own equipment from pre-energization inspection through first energization and turnover, working from manufacturer startup procedures, single-line diagrams and project commissioning scripts.

• Location: Houston or Abilene, TX (field-based, project travel)
• Reports to: Electrical Services Supervisor
• Type: Temporary, full-time hours

• Competitive hourly pay, based on experience
• 40 hours a week guaranteed
• Overtime at 1.5 times your hourly rate
• Rotations and extended shifts during energization windows

Aurora is a Houston-based electrical field services company certified to ISO 9001, 14001 and 45001, and part of an international multi-disciplinary energy services group.

Switchboards and switch gear (LV and MV)

• Perform pre-energization inspections: torque verification, bus and cable terminations, barriers, grounding, labeling and mechanical interlocks.
• Conduct insulation resistance (megger), contact resistance (DLRO) and hi-pot testing on bus, breakers and cables.
• Test, set and verify trip units and protective relays (overcurrent, ground fault, differential) against the coordination study.
• Perform primary and secondary injection testing of LV power and molded-case breakers, and vacuum bottle integrity and timing tests on MV breakers.
• Verify CT/PT ratios, polarity and wiring; perform point-to-point control wiring checks.
• Functionally test controls, interlocks, transfer schemes (ATS/MTS), metering and SCADA/communication points.
• Execute energization: phasing checks, voltage and rotation verification, and load verification.

Transformers (pad-mount, dry-type and liquid-filled substation)

• Receive and inspect units: impact recorders, nitrogen pressure, nameplate, accessories and shipping damage.
• Perform turns ratio (TTR), winding resistance, insulation resistance, polarization index and power factor/tan delta testing.
• Test and verify tap changers (DETC/LTC), bushings, gauges, alarms, cooling fans and protective devices.
• Pull oil samples for DGA and dielectric analysis where applicable.
• Support transformer energization, including inrush monitoring and post-energization checks.

Documentation and coordination

• Complete test reports and commissioning forms to NETA ATS and project specifications; flag deficiencies and track them to closure.
• Coordinate with EPCs, OEM field service, utility representatives and owner's engineers on LOTO, switching orders and energization windows.
• Lead or support crews of technicians and helpers; mentor junior staff.

• 3+ years of hands-on testing and startup of LV/MV switch gear, switchboards and power transformers.
• Proficiency with common test sets: insulation testers, DLRO, TTR, winding resistance, and primary and secondary injection (Omicron, Doble, Megger SMRT/Freja or equivalent).
• Ability to read and work from single-line and three-line diagrams, schematics, wiring diagrams and relay settings files.
• Working knowledge of NFPA 70E, NETA ATS and OSHA electrical safety requirements.
• Experience with lockout/tagout and switching on energized systems up to at least 15 kV.
• Clear, accurate test documentation habits.
• Valid driver's license and ability to pass a background check and drug screen.
• Ability to travel to project sites for extended periods.

• NETA Level II, III or IV certification (or NICET equivalent).
• Utility-scale solar, BESS/PCS, substation or data center commissioning experience (Level 3 to 5 functional testing).
• Relay testing experience with SEL, GE Multilin, Schneider or ABB relays,…
