Senior Mechanical Engineer

CoolStar Innovation Technology Limited; Hong Kong; Presencial; HKD 420.000 - 780.000; Jornada completa

Descripción de la vacante

CoolStar Innovation Technology Limited in Hong Kong is seeking an experienced mechanical design engineer to own end-to-end structural design for NEV, IDC, and cold chain product lines. You will drive system-level requirements, select components, and deliver 3D models, 2D drawings, and BOM for mass production.

You will lead prototype builds, validation campaigns, and design iterations, collaborating with electrical, thermal, and manufacturing teams to influence upstream decisions.

Formación

• Bachelor's degree or above in Mechanical Engineering or related discipline.
• 3+ years of mechanical structural design experience with mass production delivery.

Responsabilidades

• Own end-to-end mechanical structural design across NEV, IDC, and cold chain product lines from concept to mass production handoff.
• Lead system-level requirements analysis and define structural design strategies for complex multi-domain products.
• Develop and review 3D models, 2D drawings, BOM; set design standards and review outputs.
• Identify and resolve high-complexity structural challenges in thermal management, NVH, and reliability.
• Own product design quality, schedule, and cost; manage risks and trade-offs across DFM, reliability, and performance.
• Lead prototype builds, validation campaigns, and design iterations through to product sign-off.
• Collaborate with electrical, thermal, and manufacturing teams; influence upstream design decisions.
• Mentor junior engineers and contribute to team capability building.

Descripción del empleo

• Own end-to-end mechanical structural design across NEV, IDC, and cold chain product lines — from system architecture and concept definition through to mass production handoff.
• Lead system-level requirements analysis; define structural design strategies for complex, multi-domain products; drive component selection, calculations, and design validation for critical mechanical and transmission elements.
• Develop and review complete engineering deliverables (3D models, 2D drawings, BOM); set design standards and review junior engineers' outputs.
• Identify and resolve high-complexity structural challenges in thermal management, NVH, and reliability; act as the technical escalation point within the team.
• Own product design quality, schedule, and cost; proactively manage risks and trade-offs across DFM, reliability, and performance requirements.
• Lead prototype builds, validation campaigns, and design iterations through to product sign-off; define test plans and acceptance criteria.
• Serve as a key technical contributor in cross-functional projects; collaborate with electrical, thermal, and manufacturing teams and influence upstream design decisions.

Mentor and coach junior and mid-level engineers; contribute to team capability building and knowledge sharing.

Requirements:

• Bachelor's degree or above in Mechanical Engineering, Mechanical Design & Manufacturing, Fluid Machinery, Mechatronics, or a related discipline.
• 3+ years of mechanical structural design experience with a proven track record of delivering complex products to mass production; deep expertise in at least one of NEV, IDC cooling systems, or cold chain equipment.
• Strong command of mechanical transmission design, motor/reducer selection, and system-level structural design — able to work independently on ambiguous, first-of-kind problems.
• Thorough understanding of metallic and non-metallic materials and manufacturing processes (injection molding, stamping, die casting, sheet metal, surface treatment); sharp instincts for structural feasibility and cost impact.
• Expert-level proficiency in SolidWorks or Creo/Pro-E; solid experience with tolerance stack-up analysis; hands-on ANSYS structural or fluid simulation experience preferred.
• Deep knowledge of DFM, reliability engineering, and validation methodology; experience defining and executing test plans.
• Comfortable driving decisions under uncertainty; strong engineering judgment, clear communication, and the credibility to influence cross-functional stakeholders.
