About the Role

This role owns the mechanical architecture and detailed design of residential energy storage products, including installation, thermal performance, ingress protection, reliability, manufacturability, and appearance quality.

Key Responsibilities

1. Develop mechanical solutions for complete residential energy storage systems, battery packs, and inverters, including 3D models, engineering drawings, prototype follow-up, enclosures, mounting, thermal management, and water- and dust-resistant structures.

2. Optimize mechanical solutions based on product application needs and international certification requirements to meet ingress-protection, mechanical-strength, vibration, thermal, and corrosion-resistance targets.

3. Lead structural component selection, cost assessment, and manufacturability analysis. Coordinate production introduction and resolve assembly, process, and appearance issues during prototype, pilot-production, and mass-production stages.

4. Perform thermal and structural-strength simulation and reliability validation, and optimize system thermal design for different outdoor operating environments.

5. Produce mechanical drawings, bills of materials, process specifications, and test standards, and establish standardized mechanical design practices.

6. Perform tolerance-stack, dimensional, DFMEA, and design-for-manufacturing analyses and define critical mechanical characteristics and inspection requirements.

7. Participate in supplier reviews, tooling reviews, first-article approval, and corrective action for structural-component quality issues.

8. Work with certification and test teams to develop mechanical reliability and environmental validation plans and optimize designs based on test results.

Requirements

9. Bachelor's degree or above in mechanical design, mechanical engineering, or a related discipline. At least 10 years of mechanical design experience for energy storage products. Experience designing PCS or inverter structures is preferred.

10. Proficiency with mainstream 3D modeling and engineering drawing tools, with expertise in the mechanical, thermal, and water- and dust-resistant design of complete energy storage systems and battery packs.

11. Familiarity with applicable international product safety, ingress-protection, and mechanical reliability standards for energy storage products.

12. End-to-end experience from prototype development through mass production, familiarity with sheet-metal, plastics, and die-casting processes, and the ability to independently resolve mechanical assembly issues.

13. Able to prepare mechanical design, testing, and manufacturing documents in English.

14. Experience in tolerance-stack analysis, dimensional analysis, DFMEA, and design for manufacturing.

15. Familiarity with tooling, surface treatment, sealing, fastening, and assembly design is preferred.
