Responsibilities

Job Purpose

This role will be responsible for establishing overall project design basis (utility scale solar, BESS, and interconnections), oversee project engineering of primarily solar projects through the development, design, construction, and commissioning phases, and to provide successful hand off including necessary training to Operations Team to ensure ease of transition. Specifically, this position will work with Project Management teams (Pre-Construction and Construction) and external contractors to develop Utility Scale Solar PV design/construction packages including interconnection requirements, solar design requirements, solar array layouts, electrical one-lines, collection systems, collection system studies, module selection, string sizing, ground coverage ratio, inverter selection, inverter power factor requirements, inverter loading ratio, equipment installation details and cable sizing for Utility Scale Solar PV systems that may also include Battery Energy Storage Systems (BESS). This position will also support utility-scale wind projects as needed, wind experience a plus.
