• Proven experience supporting utility-scale (100MWh+) energy storage projects is preferred.

Responsibilities

• Lead the design of energy storage solutions across grid-side, generation-side (renewable + storage), and standalone/shared energy storage power stations.
• Develop integrated system solutions covering PCS, EMS, BMS, and substation systems.
• Analyze grid dispatch requirements and technical challenges in renewable grid integration.
• Take the lead in large-scale energy storage project tenders.
• Prepare technical proposals, including equipment selection, system topology design, and technical deviation analysis.
• Ensure compliance, competitiveness, and technical excellence of proposals.
• Evaluate system integration solutions for utility-scale storage projects.
• Conduct electrical calculations and simulation analysis for various applications (frequency regulation, peak shaving, black start, etc.).
• Support sales teams in cost estimation and pricing strategy at project level.
• Support project execution from design through construction and delivery.
• Resolve technical issues related to electrical interfaces, communication protocols, and grid integration.
• Track regional energy storage policies (capacity compensation, spot market rules, grid connection requirements, etc.)
• Analyze market dynamics and regional characteristics
• Contribute to white papers and technical roadmap reports for grid-side energy storage
• Develop technical documentation such as: Delivery & acceptance SOPs
• Deliver technical training to sales and project teams to accelerate commercialization
• Benchmark leading competitors (e.g., Sungrow, HyperStrong)
