We are looking for a Senior Mechanical Engineer to join Fauna Robotics, an Amazon company focused on creating delightful robots for everyday life. This role involves designing, prototyping, testing, and scaling mechanical systems for robotic applications. The ideal candidate will have a strong background in mechanism design and mechatronics, and will work closely with interdisciplinary teams to bring products from concept to production. You will be at the forefront of making robotics more accessible and enjoyable to build.

• 10+ years of experience in mechanical engineering.
• Master's degree in electrical engineering, computer engineering, or equivalent.
• Experience with CAD software such as Solidworks, Onshape, NX, or Catia.
• Strong knowledge of prototyping and mechanism design.
• 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.
• Experience working with interdisciplinary teams to execute product design from concept to production.
• Experience with 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.

• Develop prototypes and refine designs for robotic mechanisms and subsystems.
• Create and optimize precision mechanical systems, including linkages, joints, and actuation systems.
• Collaborate with electrical and software engineers to integrate sensors, actuators, and control systems.
• Partner with in-house designers to meet product aesthetic and cosmetic requirements.
• Design parts for machining, casting, 3D printing, and other manufacturing processes.
• 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.

• Employees at Amazon are often offered comprehensive health benefits—including multiple medical plan options (no pre-existing condition exclusions, 100% covered in-network preventive care), dental and vision plans, a 24/7 medical advice line from day one, expert second-opinion services, and broad mental-health support with several free counseling sessions (including pediatric). Financial wellness typically includes a 401(k) with company match (up to 2%), Restricted Stock Units (equity), FSAs, an emergency savings program, product and partner discounts, and even college-savings and home-purchase programs. Overall, the package is designed to support employees and their families’ health, finances, and day-to-day life.
