• Direct experience with TARA, PSS®E, PSLF, and PSCAD required/preferred.

• Experience building and maintaining models for renewable energy projects highly valued.

• Advanced knowledge of modeling IBRs, power plant controllers, wind-turbines, reactive power compensation and BESS systems.

• Proficiency with PSCAD for transient stability and EMT simulations (training available if needed).

• Familiarity with PowerWorld, TSAT, ASPEN, or similar tools is a plus.

• Strong knowledge of NERC Reliability Standards (MOD-025/026/027/032, PRC-024/029), ISO/RTO tariffs, IEEE 2800, and large generation interconnection processes.

• Ability to interpret inverter and power plant controller settings, and field tests, translating into accurate model packages.

• Strong analytical, organizational, and problem-solving skills.

• Excellent written and verbal communication; ability to simplify complex technical concepts for diverse audiences.

• Proven ability to manage multiple priorities under tight deadlines.

• Proficiency with Microsoft Office Suite preferred.

• Bachelor of Science Degree in Electrical Engineering, or related field. Graduate degree preferred.

• This position will travel 20% of time

• Position will require sitting for long periods of time as well as occasionally lifting up to twenty-pound boxes.
