Experience with one or more major ISO/RTO markets, with PJM, ERCOT and CAISO preferred. Working knowledge of PSCAD, PSS®E, PSLF, EMTP‑RV, PowerFactory, ETAP, or comparable power system analysis tools. Experience evaluating BESS, hybrid generation, renewable integration, or co‑located energy systems. Strong project management, communication, and stakeholder management skills. Preferred Qualifications Professional Engineer (PE) license. Experience with Hardware‑in‑the‑Loop testing, EMT modeling, and inverter‑based resource performance. Familiarity with NERC, FERC, IEEE 2800, IEEE 1547, and applicable ISO/RTO interconnection requirements. Experience supporting projects at 230 kV, 345 kV, or 500 kV transmission voltages. Knowledge of data center resiliency architectures, including islanding, black start, demand response, and hybrid energy systems. MBA or advanced degree in Power Systems is a plus. Compensation and Benefits Competitive base salaries commensurate with experience with an annual cash bonus (based on Company and individual performance). Generous paid leave. Employee participation in Long Term Incentive Plan. Comprehensive benefits package including medical, dental, vision, life, and disability insurance, including coverage for domestic partners and eligible domestic partner children.
