Senior Interconnection Engineer

Senior Interconnection Engineer Trajectory Energy Partners, a solar and storage development company, is seeking a Senior Interconnection Engineer to lead technical execution of our interconnection strategy for connecting solar and storage projects to the electric grid. This is a senior role for someone who combines deep technical knowledge of grid interconnection with the strategic ability to manage a growing project portfolio across multiple utility territories and regulatory environments. Trajectory works with communities across the Midwest, Mid-Atlantic, and Southeast to develop front-of-the-meter solar and storage projects, focusing primarily on distribution-scale projects. Specific responsibilities include: Interconnection Strategy & Queue Management Help drive Trajectory's grid interconnection strategy across all active markets, including application timing, queue positioning, and participation in utility study processes. Manage the full interconnection lifecycle for a portfolio of solar and storage projects — from initial application and feasibility screening through executed interconnection agreements and energization. Monitor changes to utility tariffs and state interconnection rules and translate those developments into actionable strategy for the development team. Identify interconnection risk early in the project development process, flagging cost exposure and technical barriers before significant capital is committed. Maintain accurate, up-to-date tracking of queue status, study milestones, deposit schedules, and cost estimates across all active projects. Technical Analysis & Engineering Oversight Review and interpret interconnection study results and communicate findings clearly to internal teams. Evaluate network upgrade scopes and costs to assess project viability and inform go/no-go decisions. Coordinate with external engineers and consultants on technical analysis, study responses, and cost negotiations. Oversee the preparation and submission of interconnection applications, ensuring accuracy, completeness, and strategic timing. Conduct early-stage interconnection screening for prospective sites to support site selection and pipeline development. Utility & Regulatory Relationships Build and maintain strong working relationships with utilities, electric cooperatives, and ISO/RTO staff across Trajectory's markets. Lead communications and negotiations with utilities on interconnection study scope, cost allocation, upgrade responsibilities, and agreement terms. Represent Trajectory in utility stakeholder processes and industry working groups related to grid access and interconnection policy. Work closely with development, legal, and finance teams to ensure interconnection timelines and costs are accurately reflected in project schedules and financial models.
