The manager will direct the application engineering and drafting resources, improve proposal tools and customer‑facing technical materials, and accelerate the qualification and integration of critical components including batteries, inverters, transformers, and switchgear.

Requirements

Essential duties and responsibilities include, but are not limited to the following:

• Lead development of technical proposals supporting the sales process, including conceptual and detailed system designs.
• Review customer RFPs and translate requirements into system configurations, layouts, and performance expectations.
• 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.
