Power Distribution Expert

Location: Singapore Employment type: Full-time Vacancies: 1

About the Role

This role owns the low-voltage distribution architecture and customer-side interface design of residential energy storage systems, ensuring that capacity, protection, grounding, temperature-rise, and installation solutions meet target-market requirements.

Key Responsibilities

1. Design power distribution solutions for residential energy storage systems, including BMS, PCS, and customer-side distribution applications.
2. Develop power distribution architectures, capacity calculations, component selection, protection coordination, cabling, and grounding designs. Produce schematics, wiring diagrams, bills of materials, and technical specifications.
3. Design customer-interface power distribution products and select and validate key components such as circuit breakers, contactors, relays, and surge protective devices.
4. Develop power distribution solutions that comply with electrical codes, grid-connection requirements, and installation rules in major target markets, including Europe and North America.
5. 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.
6. Perform protection selectivity and coordination studies and short-circuit and fault-current assessments, and prepare critical design calculations.
7. Participate in safety reviews and failure-mode analysis for distribution solutions and identify risks involving miswiring, overload, short circuit, grounding, and surge events.
8. Support preparation of installation manuals, wiring instructions, and field technical materials and help resolve certification, pilot-production, and installation issues.

Requirements

1. Bachelor's degree or above in electrical engineering, power systems, power electronics, automation, or a related discipline. At least 8 years of design experience in low-voltage distribution, power products, photovoltaic systems, or energy storage systems.
2. Familiarity with single-phase, split-phase, and three-phase low-voltage distribution systems and with the architecture and design of grid-connected, off-grid, backup-power, and automatic-transfer systems.
3. Proficiency in capacity and load calculation, cable selection, short-circuit current calculation, insulation coordination, grounding, and temperature-rise design.
4. Familiarity with low-voltage distribution, electrical installation, safety, and grid-connection requirements in major target markets, with end-to-end experience from solution design through certification and mass production.
5. Proficiency with mainstream electrical design tools. Able to prepare technical documents and conduct international technical collaboration in English.
6. Project experience in protection coordination, selectivity studies, and short-circuit current calculation.
7. Ability to independently review electrical schematics, wiring diagrams, installation drawings, and critical design calculations.
