Key responsibilities 主要职责: 1. Devise and validate specifications through use of modeling techniques combined with solid hands-on mechanical and system design knowledge. 2. Design of system and integration to the total system, including requirements and concept, CAD modeling and mechanical design, design reviews, vendor management, parts procurement, prototypes integration, and performance characterization. 3. Extensive design experiences in precision mechanisms, vacuum design, structural frames, thermal design; 4. Apply design best practices to ensure reliability, manufacturability, and serviceability within reasonable cost. 5. Exercise independent judgment in developing methods, techniques, and evaluation criterion for obtaining the expected results. 6. Activities will include working with cross-functional groups to define specifications and then to work from concept and feasibility, through architectural and detailed design, and to analyze, prototype, and test to those specifications followed by supporting the product roll-out. 7. Documentation release to production, design changes, and configuration management. 8. The ideal candidate will be highly motivated, good teamwork. Key requirement 资历要求 : 1. MS in ME or equivalent, good at English communication and writting, pass CET-6; 2. Min. of 3 years relevant experience in mechanical and system design. 3.
