Senior Mechanical Engineer

Key Responsibilities

--------------------

• Lead the overall architecture design and technical requirement breakdown of planetary reducers for robotic joints, including reduction stages, reduction ratios, configurations, gear parameters, and power flow design.
• Design sun gears, planet gears, ring gears, planet carriers, shafts, and supporting bearings, and optimize strength, stiffness, durability, efficiency, and weight.
• Perform gear contact stress and bending strength analysis, load distribution analysis, transmission error analysis, backlash optimization, and gear microgeometry modification to improve noise, vibration, shock, and dynamic performance.
• Define lubrication, sealing, materials, heat treatment, surface strengthening, and tolerance systems to achieve high load capacity, high efficiency, low wear, and consistent mass-production quality.
• Drive the integrated design of the planetary reducer with frameless motors, encoders, brakes, torque sensors, housings, and output structures to optimize overall dimensions, weight, and packaging space.
• Develop DV/PV validation plans and coordinate testing for efficiency, backlash, torsional stiffness, temperature rise, NVH, shock, durability, and environmental performance. Lead root cause analysis and drive corrective actions for identified failures.
• Establish platform-level design standards, calculation methodologies, technical databases, DFMEA, critical characteristics, and design review processes for planetary reducers.
• Collaborate with suppliers, purchasing, manufacturing, and quality teams on process reviews, DFM/DFA, cost optimization, proces...
