The ideal candidate brings deep renewable energy engineering knowledge, strong analytical skills, and the ability to translate complex technical concepts clearly for customers and project teams.

Respond to customer technical questions and requests for information (RFIs) in coordination with the Sales team. Support Sales in understanding applicable incentive programs (ITC, IRA adders, SGIP, USDA REAP, net metering) and their impact on project economics. Technical Project Development Lead technical development of solar PV, battery energy storage, microgrid, and EV charging projects from early-stage feasibility through construction handoff, support construction and project management teams through to project completion. Evaluate system layout and design options based on customer site information, as-built drawings, and load profiles. Perform energy modeling, battery dispatch modeling, and utility cost/rate analysis to size and optimize systems. Assess microgrid configurations including islanding capabilities, resiliency design, and grid services potential. Visit customer sites to investigate project feasibility, electrical infrastructure, and interconnection methods. Coordinate onsite engineering and investigative activities with utilities, outside engineers, surveyors, and vendors. Make equipment selections based on project needs, technology performance, material availability, and costs. Develop and maintain financial models and project pricing during the development phase. Generate project budgets and schedules in conjunction with the Pre-Construction team. Provide technical support to Pre-Construction in the preparation of requests for bids. Interconnection, Permitting & Regulatory Manage utility interconnection submittals (NEM, SGIP, Rule 21, or applicable tariffs) and serve as primary point of contact with the utility. Oversee AHJ permitting submittals and coordinate responses through approvals. Monitor interconnection queue status and proactively manage schedule impacts. Identify applicable incentive programs including ITC, IRA adders, SGIP, USDA REAP, and state/local programs, and support their incorporation into project financial models. Construction Support & Closeout Consolidate and review project deliverables and technical documents generated by outside engineering and vendors. Support the Project Management team on material procurement and technical guidance during construction. Manage technical components of commissioning and project closeout following construction completion. Perform and/or review energy production, savings calculations, and financial evaluations of completed projects. Perform other duties as required. Minimum Qualifications: Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Civil Engineering, Construction Engineering, or related discipline. Minimum of 3 years of relevant experience in renewable energy project development, engineering design, or related field. Demonstrated experience with solar PV and/or battery energy storage project development. Familiarity with utility interconnection processes and permitting for distributed generation. Additional Qualifications: NABCEP PV Installation Professional or PV Technical Sales certification strongly preferred. Professional Engineering (PE) license, Certified Energy Manager (CEM), or LEED AP not required but considered a plus. Experience with microgrid design, islanding configurations, and/or grid services a significant plus.

Experience with energy storage incentive programs and dispatch optimization modeling. Proficiency with solar and storage design/modeling software: PVSyst, Helioscope, Aurora, Energy Toolbase, Xendee, and/or HOMER Pro. Excellent verbal, written, and presentation communication skills; ability to convey complex technical solutions clearly to non-technical audiences. Comfortable working alongside Sales Executives in customer meetings, site walks, and proposal presentations in a technical support capacity. Ability to analyze utility rate structures and model bill savings and financial returns (NPV, IRR, simple payback). Proficient in Microsoft Office Suite (Word, Excel, PowerPoint); experience with project scheduling tools a plus. Ability to travel up to 25% of the time for site visits and customer meetings.
