About the role
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, process capability development, and mass production launch.
What We Are Looking For
- Bachelor's degree or above in Mechanical Engineering, Automotive Engineering, Mechatronics, Precision Mechanical Engineering, or a related field. A Master's degree or above is preferred.
- At least 5 years of R&D experience in gear transmission systems or reducers, with hands-on product development experience in planetary reducers or precision planetary gear systems.
- Strong knowledge of planetary transmission principles, gear geometry, strength and life calculations, load sharing, backlash control, bearing selection, and shaft system design.
- Familiar with gear materials, heat treatment, gear grinding/honing, surface strengthening, lubrication and sealing, gear accuracy grades, and major failure modes.
- Proficient in Creo or equivalent 3D CAD tools, with hands-on experience in at least one transmission analysis tool such as KISSsoft, Romax, or MASTA.
- Experience with finite element analysis tools such as ANSYS.
- Ability to independently manage requirement breakdown, concept development, detailed design, engineering drawings and tolerance definition, prototype debugging, validation analysis, and design improvements.
- Strong structured problem-solving, cross-functional collaboration, and technical communication skills.
- Ability to read technical documentation in English and handle routine written communication in English.
Preferred Qualifications
- End-to-end project experience in precision planetary reducers, from concept design through mass production launch.
- Experience with robotic rotary joints, collaborative robot actuators, servo systems, or compact high-torque transmission products.
- Experience developing reducers with low backlash, high torsional stiffness, high efficiency, low NVH, or high shock-load capability.
- Familiarity with the integration requirements of motors, encoders, brakes, torque sensors, and output bearings in robotic joints.
- Familiarity with APQP, DFMEA, DVP&R, 8D, GD&T, and automotive-grade product development and quality processes.
- Experience in patent development, supplier technical management, platform planning, or leading a small technical team.
