• Layout Modeling & Software Execution: Configure preliminary rooftop, carport, and ground-mount PV arrays in Helioscope and CAD Software, observing fire setbacks, structural obstacles, and shade obstructions.
• Bidding & Estimating Configuration: Input system specifications (modules, inverters, optimizers, racking systems, service voltage) into bidding software to prepare cost estimates and scope descriptions.
• Voltage & Electrical Verification: Verify electrical service ratings (208V, 240V, 480V three-phase vs. single-phase) and main panel busbar capacities against preliminary design drawings.
• Sales & Estimating Coordination: Process incoming sales requests, organize preconstruction project documentation, track vendor equipment quotes, and support lead estimators in clarifying bid deliverables.
• Site Walk & Quantity Take-Off Assistance: Assist project teams during preliminary site walks, taking field measurements and compiling basic electrical/civil material take-offs.

Qualifications & Technical Requirements

• Education: Bachelor’s degree in Electrical Engineering, Civil Engineering, Construction Management, or a related technical discipline (recent engineering graduates welcomed).
• Experience: 0 – 2 years of experience in solar PV design, project engineering, or electrical estimating.
• Software Proficiency: Foundational knowledge of CAD software, Energy Simulation Software’s, and Google Workspace / MS Office.
• Blueprint Reading: Ability to read and interpret single-line diagrams (SLDs), electrical panel schedules, and architectural blueprints.
• Industry Knowledge: Basic understanding of National Electrical Code (NEC 70) principles and commercial solar electrical systems.
