Senior Mechanical Engineer- Actuators and Gearbox , Fauna

About the role

We are seeking a talented and experienced Senior Mechanical Engineer to join our actuator team. You will play a pivotal role in designing, prototyping, testing, and scaling the actuator systems for our robotic systems. This role requires a strong background in motor and precision gearing design, including broader knowledge around motor electromagnetics, transmission types, sensing, structural components, and thermal management. You will help drive actuator development across the full engineering lifecycle while establishing scalable design, test, and integration practices for future robotic platforms.

Key job responsibilities

• Lead the selection, design, and integration of robotic actuators.
• Create and optimize precision mechanical systems, including linkages, joints, and actuation systems
• Collaborate with electrical and software engineers to integrate sensors, drive electronics, and control systems
• Define actuator requirements around torque density, bandwidth, efficiency, thermal performance, back drivability, inertia, reliability, manufacturability, and cost.
• Develop test infrastructure and expertise for measuring performance and reliability.
• Work with suppliers and manufacturers worldwide to source components, manage production timelines, and maintain quality standards
• Perform life-cycle testing, quality assurance, and failure analysis to validate designs and ensure product reliability
• Oversee the transition of designs from prototype to mass production, including working directly with manufacturing partners globally
• Maintain detailed design documentation, including CAD models, drawings, and test data

Basic Qualifications

• Bachelor's degree or above in robotics, mechanical/mechatronics engineering, systems engineering or related field
• Experience in developing functional specifications, design verification plans and functional test procedures
• 7+ years of working designing gears systems, robotic actuators, or precision mechatronic hardware.
• Experience with CAD software (Solidworks, Onshape, NX, Catia, etc)
• Strong understanding of motors, transmissions, bearings, encoders, structural design, thermal management, and precision mechanical integration.
• Proficiency in designing machined, cast, and 3D-printed parts
• Experience with mechatronics, including sensors, actuators, and motion control systems
• Understanding of manufacturing processes and working with a global supply chain

Preferred Qualifications

• Experience working with interdisciplinary teams to execute product design from concept to production
• Experience with the project management of technical projects
• Previous experience in robotics or control systems
• Knowledge of finite element analysis (FEA) and simulation tools for stress, thermal, and dynamic analysis
