• Familiarity with single-phase, split-phase, and three-phase LV distribution systems.
• Experience with grid-connected, off-grid, backup-power, and automatic-transfer systems.
• Proficiency in capacity and load calculations, cable selection, short-circuit calculations, insulation coordination, grounding, and temperature-rise design.
• Proficiency with mainstream electrical design tools.
• English for international collaboration.

Responsibilities

• Design LV distribution solutions for residential energy storage systems, including BMS, PCS, and customer-side distribution applications.
• Develop power distribution architectures, capacity calculations, component selection, protection coordination, cabling, and grounding designs. Produce schematics, wiring diagrams, bills of materials, and technical specifications.
• Design customer-interface power distribution products and select and validate key components such as circuit breakers, contactors, relays, and surge protective devices.
• Develop power distribution solutions that comply with electrical codes, grid-connection requirements, and installation rules in major target markets, including Europe and North America.
• Work with research and development, test, and certification teams on system integration, prototype debugging, corrective action, and production introduction, and establish standardized and modular power distribution design practices.
• Perform protection selectivity and coordination studies and short-circuit and fault-current assessments, and prepare critical design calculations.
• Participate in safety reviews and failure-mode analysis for distribution solutions and identify risks involving miswiring, overload, short circuit, grounding, and surge events.
• Support preparation of installation manuals, wiring instructions, and field technical materials and help resolve certification, pilot-production, and installation issues.
