Description

We’re seeking a Sr. Solar & Energy Storage Systems (ESS) Design Engineer to join our growing renewable energy team. This is a key, hands-on engineering role responsible for the end-to-end design of solar photovoltaic (PV) and energy storage systems for commercial and industrial applications.

• Maintain accurate documentation of design revisions and decisions.
• Conduct site walks to assess feasibility of solar and energy storage installations.
• Support the interconnection process with IOUs and municipal utilities (PG&E, SCE, SDG&E, etc.).
• Ensure compliance with NEC 690/705/706, UL 9540/1741-SA, IEEE 1547, and utility-specific interconnection standards.
• Design or coordinate technical specifications for PV and ESS systems—balancing materials, site conditions, and contractual requirements.
• Coordinate with internal teams (Development, Construction, Project Management) and external partners (Utilities, AHJs, Clients).
• Provide technical guidance during permitting, construction, and commissioning.
• Work with industry-leading engineers and project teams who value precision, innovation, and collaboration.
• Gather and analyze structural, electrical, and site data for design development.
• Develop detailed electrical and physical designs, including site plans, SLDs, conduit/wire schedules, grounding, and interconnection packages.
• Develop and maintain design standards, templates, and best practices.
• Perform system modeling, yield analysis, and load studies using PVSyst, Helioscope, NREL SAM.

Requirements

This position offers the opportunity to lead complex projects, collaborate across multiple disciplines, and influence the next generation of renewable system designs.
