• Translate energy storage application needs into specific BMS, battery module/pack, and rack/system requirements, focusing on electrical, mechanical, thermal, environmental, reliability, and compliance aspects.
• Drive the development of energy storage systems that are battery technology-agnostic, allowing for a range of cell chemistries (e.g., Lithium-Ion – NMC, LFP) and pack architectures.
• Work with Director of Emerging Technologies to evaluate future battery technologies and qualifying applicability to Fluence’s products.


• Supplier and Design Reviews:
• Review and assess battery supplier specifications for cells and modules, ensuring alignment with BESS requirements.
• Lead technical design reviews and approval for BMS and Battery Packs, ensuring that designs meet all performance, reliability, and safety objectives.
• Ensure seamless integration of BMS with battery modules, optimizing for cost, safety, and manufacturability.


• Design Validation and Testing:
• Oversee the creation and execution of test plans and procedures for BMS and battery pack validation, covering critical performance metrics such as thermal management, charge/discharge cycles, and safety compliance.
• Lead FMEA, DFM, and DFA reviews for battery platforms, focusing on identifying and mitigating design risks early in the development process.


• Cross-Functional Support:
• Collaborate with global R&D teams in addressing technical challenges, leading root cause analysis, and ensuring the resolution of battery-related issues.
• Support System-Level Testing for BESS products, ensuring that battery packs perform optimally within the broader energy storage system.
• Provide technical support to manufacturing and supply chain teams for supplier development, alternate component qualification, and mass production scalability.
• Assist quality teams in root cause analysis and driving corrective actions when issues arise in production or field operations.


• Regulatory and Safety Compliance:
• Ensure compliance with industry standards and regulatory requirements, including certifications such as UL, IEC, and others related to battery systems.
• Lead engineering standards for battery safety design and testing, ensuring that products meet the highest global safety standards.


• Technology Adoption and Customer Support:
• Work closely with regional business units to drive the successful adoption of battery platforms for BESS products, providing ongoing technical support during product integration and deployment.
• Serve as the primary technical point of contact for both internal and external customers on battery-related issues, ensuring smooth communication and issue resolution.
