• Evaluate and support projects across solar, wind, BESS, substations, transmission, and distribution
• Prepare and review technical deliverables including study reports, design criteria, specifications, study documentation, scopes of work, and other engineering packages
• Participate in client meetings, technical discussions, occasional site visits, and field walkdowns
• Support proposal efforts, technical approach development, and estimating for new project opportunities
• Ensure studies and engineering deliverables align with applicable codes, standards, utility requirements, and internal quality expectations
• Stay current with regulatory changes, grid codes, ISO/RTO requirements, and evolving standards related to interconnections and inverter‑based resources
• Contribute to the improvement of internal workflows, tools, and methods that help streamline studies, model checks, and engineering efficiency

What We’re Looking For

• Bachelor’s Degree in Electrical Engineering from an ABET‑accredited program
• Strong experience supporting interconnection studies and power systems analysis
• Experience with tools such as PSSE, PSCAD, PSLF, ASPEN, PowerWorld, ETAP, SKM, CYME, EMTP, or similar
• Experience performing dynamic studies, model development, or renewable system analysis for high‑voltage or utility‑scale projects
• Strong understanding of power system behavior, inverter‑based resources, and grid interconnection requirements
• Familiarity with ISO/RTO processes such as ERCOT, MISO, SPP, PJM, CAISO, or similar is a plus
• Understanding of applicable standards such as NERC PRC/MOD, IEEE 2800, IEEE 1547, and other relevant interconnection requirements
