- Establish grounding strategies, protection schemes, and isolation methods for high-power systems
- Ensure compliance with UL, IEC, and IEEE standards relevant to power electronics and grid interconnection.
- Participate in DFMEA,DVTand EVT/PVT activities for new product development.
Energy Storage & Equipment Integration
- Serve as Subject Matter Expert (SME) on energy storage systems, including residential and C&I ESS applications
- Apply strong knowledge of Li-ion battery technologies and Battery Management Systems (BMS)
- Evaluate and analyze energy storage technologies, products, and vendors, support vendorselectionand system implementation.
Equipment Specification & Integration
- Develop or direct the creation of equipment specifications, procurement plans, and factory acceptance testing (FAT) for batteries, grid-tied inverters, battery enclosures, and related components
- Ensure designs align with applicable safety and certification standards (UL 9540, UL 1973, and related frameworks)
- Coordinate electrical design with mechanical layouts and enclosure constraints
Technical Analysis & Risk Management
- Identifyand mitigate electrical risks, including fault current, protection coordination, and thermal performance
- Guide technical decisions through data-driven analysis and engineering trade-off evaluations
- Diagnose product issues and propose effective, scalable solutions
Cross-Functional Collaboration
- Collaborate closely with firmware, mechanical, manufacturing, and validation teams to ensure seamless product integration
- Coordinate electrical designs with mechanical constraints and enclosure requirements
- Support broader business functions including product strategy and customer engagement
- Interface with clients, vendors, and external stakeholders as needed.
- Support Design for Testability (DFT) and Design Verification Testing (DVT) initiatives early in the design phase.
Documentation & Lab Management
- Maintain and continuously improve the lab's test infrastructure, including test benches, instrumentation, load banks, battery cyclers, and environmental chambers, ensure calibration, and support validation testing.
- Develop production-ready electrical documentation to support manufacturing and system integration
Leadership & Mentorship
- Provide technical leadership, mentorship, and guidance to junior engineers
- Lead and contribute to project planning, prioritization, and resource allocation
- Support broader business functions including product strategy, roadmap development, and customer engagement
- Regularly meetand correspond with clients and external partners
- All other dutiesassigned.
Required Skills and Attributes:
- Master's degree in electrical engineering or a related field (preferred)
- Minimum of8years of experience managing or leading engineering teams
