Key Responsibilities

• Develop commercial solar PV and ESS designs, including electrical layouts, single-line diagrams, site plans, and supporting technical drawings.
• Perform system modeling, production analysis, equipment selection, and design optimization.
• Review engineering designs for accuracy, constructability, code compliance, and alignment with project specifications.
• Coordinate with outside engineers and designers for specialized engineering, technical reviews, and stamped drawings when needed.
• Prepare design revisions and resolve engineering conflicts throughout the project lifecycle.
• Prepare, review, and manage engineering submittals, shop drawings, permit packages, and technical documentation.
• Coordinate with building departments, AHJs, and utility providers, including addressing plan-check corrections, RFIs, and utility interconnection requirements.
• Ensure designs comply with applicable standards including the NEC, California Electrical Code, building codes, and utility standards.
• Maintain accurate engineering records, drawing revisions, and project documentation.
• Conduct site verification (SV) and quality control (QC) visits to confirm existing conditions and installation accuracy.
• Identify design discrepancies, installation challenges, and potential code compliance issues.
• Provide technical guidance and troubleshooting support to project managers and installation crews.
• Assist with system commissioning, equipment configuration, and performance verification.
• Coordinate with equipment manufacturers and technical support teams to resolve system-related issues.
• Develop preliminary layouts, conceptual designs, and feasibility assessments for prospective commercial projects.
• Support system sizing, production modeling, equipment selection, and project estimating, including identifying electrical infrastructure requirements and potential cost drivers.
• Provide technical input during planning and preconstruction reviews.
• Complete assigned engineering tasks and deliverables within established project timelines while proactively communicating engineering challenges, project risks, and potential delays.
• Follow company policies, safety procedures, and established engineering and operational standards while demonstrating accountability and ownership.

Requirements

• Bachelor’s degree in Electrical Engineering or Civil Engineering.
• 5–7 years of relevant engineering experience, including commercial solar PV system design.
