# 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
