    • You navigate three-phase power, DC buses, and control loops with confidence.
    • You thrive in the field—tool bag in hand, laptop connected, data at your fingertips.

    Impact you’ll make

    • Own installation, commissioning, inspection, troubleshooting, and maintenance for BESS assets—batteries, inverters, transformers, EMS, and balance-of-system equipment.
    • Interpret single-line diagrams, schematics, and OEM manuals to solve electrical, mechanical, and controls problems.
    • Execute preventive/corrective maintenance; document precisely with reports, logs, and incident records.
    • Track performance via SCADA/monitoring platforms; respond to alarms, faults, and outages to protect uptime.
    • Lead or assist on upgrades, retrofits, and warranty tasks; partner with engineering, operations, and vendors.
    • Travel to multiple sites and support on-call or emergency rotations.

    What you’ll need to succeed

    • High school diploma or GED (technical or trade school training preferred).
    • 2+ years’ experience in electrical, power generation, renewables, or energy storage.
    • Strong fundamentals in DC systems, three-phase AC, and control circuits; skilled at reading single-line diagrams and detailed schematics.
    • Demonstrated high-voltage safety practices aligned with OSHA and NFPA 70E.
    • Hands-on with meters, insulation testers, and laptop interfaces for commissioning/diagnostics.
    • Background with BESS, solar PV, or wind; familiar with lithium-ion battery technology and thermal management.
    • Experience using SCADA and data tools to analyze trends and inform maintenance.
    • Certifications such as NFPA 70E, OSHA 10/30, or similar.
    • Sungrow PT1, PT2 experience.

    Physical & work requirements

    • Lift up to 50 lbs.; climb ladders and stairs as needed.
    • Willing to travel and work flexible hours, including nights/weekends.
