About the role

Key responsibilities & impact

Lead commissioning of microgrid systems including paralleling switchgear, automatic transfer switches, generator controls, inverters, DERs, BESS, and solar PV.
Serve as the on-site technical lead during commissioning, coordinating with remote controls engineers, EPC contractors, and utility interconnection personnel.
Perform pre-energization checks, insulation resistance testing, point-to-point wiring verification, relay functional testing, and protective device trip testing.
Energize 480VAC, 125VDC, and 1500VDC systems, including station battery banks, DC distribution panels, battery chargers, solar PV string combiner boxes, and BESS DC circuits.
Execute hot work, live switching, and breaker racking operations following strict safety protocols.
Perform LOTO procedures and maintain arc flash safety compliance across all field activities.
Commission medium-voltage (MV) equipment when project scope requires.

Requirements

What you’ll need

7+ years of experience in electrical field engineering, commissioning, power systems integration, or a related hands-on technical role.
Deep working knowledge of 480VAC three-phase power distribution systems, including switchgear, breakers, protective relaying, and metering.
Experience with 125VDC station battery systems, DC distribution, battery chargers, and DC control power.
Familiarity with 1500VDC solar PV and BESS string-level DC circuits.
Hands-on experience commissioning paralleling switchgear, generator controls, and automatic transfer schemes.
Proficiency pulling, terminating, and testing wire and cable, including power conductors, control wiring, fiber optic, Cat5e/6a, and serial shielded twisted pair.
Demonstrated ability to read and interpret single-line diagrams, three-line diagrams, wiring schematics, relay logic drawings, and P&IDs.
Strong understanding of protection and coordination principles: overcurrent, differential, synchrocheck, and bus protection schemes.
Proven experience with LOTO procedures, hot work, arc flash safety, and working on or near energized equipment.
Excellent troubleshooting skills with a holistic, systems-level approach.
Valid driver’s license required because this role involves regular driving to remote project sites where public transit and ride-share are not viable alternatives.
Willingness to travel 50–75% with extended on-site deployments during commissioning phases.
