ABOUT THE JOB/主要工作

Technical and Project Ownership

• Independently lead projects related to welded/metal structural components and overall load-bearing structures, owning the full 0–1 cycle from concept definition, design, prototype validation, pilot build to mass-production ramp, and taking responsibility for the overall technical solution and delivery outcomes.
• Break down system requirements, identify key technical metrics and constraints, and make clear, practical trade-offs between performance, reliability, cost, lead time, and manufacturing complexity.
• Proactively identify structural risks and systemic issues in projects, drive root-cause analysis and the implementation of long-term solutions based on data and test results, and quantitatively track and report progress, quality, and impact.
• Support junior engineers’ growth in welded structure design, tolerance stack-up analysis, and mass-production issue closure through design reviews, technical mentoring, and code/drawing reviews.

Mechanical Design and Engineering Execution

• Own the concept design and detailed modeling of key load-bearing structures such as welded frames, metal frameworks, and plate-welded structures, including structural topology, joining methods, assembly relationships, and maintainability design.
• Perform structural design and material selection for die casting, forging, aluminum extrusion, sheet metal, welding, and related surface-treatment processes, and drive the implementation of DFM/DFA/DFX, DFMEA, and reliability-engineering practices for structural parts.
• Plan and execute simulation and physical validation for structural parts (e.g., strength, stiffness, fatigue, vibration, weld deformation), using predictive analysis in early design phases to avoid high-risk designs.
• Lead or deeply participate in prototype build, test validation, failure analysis, design iteration, and yield/quality issue closure during mass production, continuously optimizing structural designs and process windows.

Cross-Functional and International Collaboration

• Work closely with industrial design, electronics, electrical, embedded, algorithms, product, supply chain, quality, test, and manufacturing teams to ensure that structural solutions are well integrated with the overall electromechanical system.
• Contribute an engineering perspective during product definition to clarify requirements and priorities, ensuring manufacturability, testability, and maintainability of structures are fully considered from the requirements phase.
• Collaborate with domestic and overseas suppliers and manufacturing partners on pilot builds, jigs and fixtures, weld-process development, tooling/mold acceptance, and production ramp-up, balancing quality, cost, and capacity goals.
• Maintain efficient communication and information alignment across locations and time zones, driving cross-team closure of structural issues and mass-production defects.

ABOUT YOU/关于你

Minimum Qualifications/基本要求

Technical Qualifications

• Bachelor’s degree or above in Mechanical Engineering, Vehicle Engineering, Materials Science, or a related field, with approximately 6–8 years of mechanical/structural R&D experience, having fully led or been deeply involved in at least two products across the full development cycle from concept to mass production.
• Solid foundation in welded and metal structural design; familiar with tubular frames, plate-welded structures, etc., with practical project experience in weld process routing, fixture design, weld sequencing, and control of weld deformation/residual stress.
• Systematic understanding of mainstream manufacturing processes such as die casting, forging, aluminum extrusion, sheet metal processing, and surface treatment; able to select materials and processes based on volume, precision, cost, and reliability, and to work with manufacturing teams to optimize yield and consistency.
• Deep understanding of engineering topics such as structural strength, stiffness, fatigue, vibration, and sealing/protection, with the ability to use simulation, analytical calculations, and experimental design to identify high-risk designs early and propose improvements.
• Strong skills in tolerance stack-up analysis and GD&T, able to complete critical dimension chain analysis and tolerance allocation during the design phase, balancing functional requirements, assembly consistency, and manufacturing complexity.
• Proficient in mainstream 3D CAD tools (such as Creo or equivalents) and 2D drawing tools, capable of producing mass-production-ready drawings, BOMs, and technical documents, and familiar with DFMEA, reliability validation, and related engineering processes.

Role Requirements

• Able to independently lead complex structural projects, break down milestones and deliverables, define validation paths, development plans, and risk-mitigation strategies, and take full ownership of results.
• Hands-on experience taking new structures/modules from 0–1 through to 1–N platformization and production iterations, with full-loop ownership across EVT/DVT/PVT/MP phases.
• Demonstrates good judgment and drive under uncertainty, able to proactively surface issues, align expectations across stakeholders, and find a pragmatic balance among schedule, quality, and cost.
• Maintains curiosity and a strong desire to dive deep into engineering problems, and is willing to continuously explore areas such as welded structures, process-window optimization, and mass-production quality improvement.

Communication and Collaboration Skills

• Strong cross-functional collaboration skills, able to build technical alignment and drive execution across structure, process, manufacturing, quality, and suppliers.
• Able to clearly articulate design rationale, trade-off decisions, and risk assessments, and willing to fully listen to feedback in reviews and iterate quickly on solutions.

Preferred Qualifications/若你具备下面的经验与经验更佳

• Experience in structural design and mass production in related industries such as AGVs, delivery robots, warehouse/logistics robots, or construction machinery (structural components).
• Proven track record in designing and commissioning aluminum welded frames, heavy-duty structural components, and complex welding fixtures, with systematic methods for weld quality control and mass-production process window optimization.
• Familiar with system-level development processes for complex mechatronic products (e.g., smart devices, robots, industrial equipment), with a solid understanding of electromechanical interface definition, assembly tolerances, and reliability design.
• Successful experience leading the closure of complex field issues, supplier onboarding, and mass-production quality improvements in areas such as reliability, cost, and yield.
• Good English reading and writing skills and basic spoken English, able to participate in cross-regional technical discussions and documentation when needed.
