• Ensure proposals incorporate optimal equipment selection for batteries, inverters, transformers, MV/LV switchgear, breakers, capacitor banks, site‑wide UPS, and associated BOS equipment.
• Perform and/or oversee key electrical engineering calculations including load flow, short‑circuit, and arc‑flash analyses.
• Review and approve single‑line diagrams, layouts, schematics, cable sizing, and other engineering deliverables.
• Benchmark new technologies, evaluate supplier offerings, and integrate new components into baseline system designs.
• Lead the component qualification process for batteries, inverters, transformers, and switchgear.
• Work closely with drafting, engineering, supply chain, sales, and project management to ensure accuracy, feasibility, and manufacturability of proposed solutions.
• Support RFIs, customer technical discussions, and contract exhibit preparation.
• Direct, plan, and manage application engineering and drafting resources to maximize efficiency, output quality, and consistency.
• Mentor and develop engineers, providing technical guidance and driving continuous improvement.
• Continuously enhance customer‑facing materials, internal engineering standards, and proposal automation tools.
• Establish and track KPIs on proposal throughput, accuracy, and efficiency
• Present solutions, system designs, and technical differentiators to customers.
• Serve as a subject‑matter expert on Company’s BESS platform and system architecture.
