About The Position

Eversource’s Transmission System Planning department supports the transformation of the electric power system while maintaining a safe, reliable, and resilient bulk electric system. The Senior Engineer serves as a technical subject matter expert conducting advanced power system modeling, simulation, and planning studies, with a focus on transmission planning, operational studies, electromagnetic transient (EMT) analysis, and inverter-based resource (IBR) integration. The role evaluates company and industry data and develops cost-effective, reliable transmission solutions for future system needs, including transmission lines, renewable generation, battery energy storage systems, FACTS devices, synchronous condensers, HVDC systems, and other emerging technologies. Studies follow Eversource, ISO New England, NPCC, and NERC requirements. The position may be based in Hartford, Connecticut; Westwood, Massachusetts; or Manchester, New Hampshire. The Senior Engineer leads and presents planning studies, provides engineering input on system solutions, exchanges results and reviews data and assumptions with regional stakeholders, and coordinates with ISO New England, transmission owners, and Eversource departments. The role also oversees vendor and consultant studies, prepares reports and presentations, contributes to long-range planning standards, and supports Transmission Operations and the Control Room through reliability and operational assessments. It develops and maintains high-fidelity EMT models, collaborates on technology research and strategy, represents Eversource on industry committees, conducts operational studies, and mentors junior and associate engineers. This role follows a hybrid schedule. Current guidelines require at least three office days each week, including Tuesdays and Wednesdays, with the third day arranged with the supervisor. Employees must be able to work in the office up to five days per week when business needs or policy changes require it. The position requires availability for emergency restoration assignments and travel among Massachusetts, Connecticut, and New Hampshire as needed. Eversource does not offer immigration-related sponsorship for this position.
