About the job
Join our innovative team at Fauna Robotics as a Senior Mechanical Engineer, where you will be instrumental in designing and developing cutting-edge actuator assemblies that drive our advanced robotic systems. You will be responsible for leading the mechanical architecture, conducting detailed CAD/FEA analysis, and validating tests for our ultra-compact, high-torque actuators, guiding them from initial concept to production release.
Key Responsibilities
- Create and evaluate actuator concepts, including custom gear trains, bearings, and housings, to achieve stringent torque-to-weight and thermal performance targets.
- Lead detailed design efforts using 3D CAD, GD&T, tolerance stacks, and structural/thermal FEA.
- Rapidly prototype designs, develop test fixtures, and characterize key performance metrics such as torque, efficiency, backlash, and thermal rise.
- Implement DFM/DFA methodologies, release drawings and BOMs, and work closely with suppliers for pilot builds.
- Collaborate across departments, including controls, firmware, and manufacturing, to enhance overall system performance.
- Manage relationships with expert independent contractors to leverage specialized skills.
- Collaborate with industrial design and systems engineering teams to balance aesthetic, environmental, and regulatory requirements.
Required Skills & Qualifications
- Education: Bachelor’s degree or higher in Mechanical Engineering, Mechatronics, or a related field.
- Experience: A minimum of 6 years of experience in designing precision actuators, motors, or motion-control hardware that has been successfully delivered to customers.
- Technical Skills:
- Deep expertise in gear train mechanisms (planetary, harmonic, cycloidal), bearing and shaft design, thermal management, and lubrication techniques.
- Proficient in CAD software (Onshape or SolidWorks) and structural/thermal FEA analysis.
- Hands-on experience in prototyping, machining, and conducting failure root cause analysis.
Preferred Qualifications
- Experience in scaling prototypes to production levels exceeding 100 units.
- Familiarity with frameless permanent magnet motors and rotor/stator integration.
- Proficiency in scripting languages (Python) for design automation and data analysis.
Why Join Us?
At Fauna Robotics, you will have the unique opportunity to contribute to groundbreaking technology in the robotics sector, enabling the next generation of humanoid robots to interact dynamically with their environment. We offer a collaborative and innovative work environment where your skills will be valued and your ideas can shape the future of robotics.
