Job Description:
VinRobotics, based in Hanoi, Vietnam, is pioneering advanced actuator technologies for humanoid robots and collaborative robotic applications. We’re looking for an experienced Mechanical Design Engineer to lead the design, prototyping, and validation of precision mechanical systems, actuator housings, gear assemblies, and integrated electro-mechanical solutions. Your contributions will directly impact the performance, durability, and manufacturability of cutting-edge robotic actuators.

Key Responsibilities:

• Develop precise 3D CAD designs for frameless motor mounts, actuator housings, high-precision gearboxes (harmonic, planetary), bearing assemblies, and sensor integration components.

• Ensure designs meet rigorous requirements for structural integrity, weight optimization, thermal management, and compact form factors.

• Build functional prototypes to verify designs, evaluate assembly methods, assess mechanical tolerances, and confirm performance under operational conditions.

• Work closely with electronics engineers, embedded software engineers, and and QA teams. Coordinate detailed testing, including torque measurements, thermal testing, vibration analysis, and endurance tests, to validate mechanical design choices.

• Solve complex integration challenges, such as encoder alignment, sensor placement, cable management, and ease of assembly.

• Generate precise 2D engineering drawings adhering to ASME Y14.5 GD&T standards.

• Identify opportunities to improve actuator designs for manufacturability, cost-efficiency, ease of assembly, and serviceability.

Required Qualifications:

• Bachelor’s or Master’s degree in Mechanical Engineering, Robotics, Mechatronics, or related engineering disciplines.

• 3+ years of experience in mechanical design and prototyping, specifically in electromechanical systems, robotics, precision assemblies, or similar fields.

• Proficiency with advanced CAD software tools (SolidWorks, Catia, Inventor).

• Demonstrated experience in mechanical tolerance analysis, detailed GD&T, and manufacturing documentation.

• Extensive knowledge of materials (metals, composites, engineering plastics), and familiarity with manufacturing methods (CNC machining, injection molding, additive manufacturing).

• Proven ability to perform and interpret FEA analyses (stress, thermal, vibration) and optimize mechanical designs accordingly.

• Strong understanding of mechanical interfaces, bearing selection, gear drive systems (harmonic, planetary), and actuator mechanics.

Preferred Qualifications:

• Direct experience designing robotic joints, actuators, high-precision gearbox systems, or similar mechatronic systems.

• Familiarity with actuator technologies (frameless motors, torque sensors, encoders).

• Experience in thermal management strategies for compact actuator systems, including active and passive cooling solutions.

• Background in working closely with electrical engineers on PCB integration, wiring, connector design, and EMC mitigation strategies.

• Familiarity with robotics industry standards and certifications (e.g., IP ratings, ISO mechanical standards, EMC directives).

• Experience managing external prototyping services, vendor negotiations, and quality inspections for outsourced parts.
