Qualifications

• Bachelor’s, Master’s, or PhD degree in Mechanical Engineering, Manufacturing, Robotics, Biomechatronics, Mechatronics, or related fields.
• 5+ years of experience (3+ years with advanced degree) designing mechanical systems in consumer products, robotics, aerospace, medical, automotive, or similar fields.
• Proven track record shipping products to market, ideally at scale.
• Experience designing for high-volume mass manufacturing DFM processes such as injection molding, sheet metal, stamping, casting, composites, or CNC machining.
• Practical hands-on experience with prototyping tools, manufacturing techniques, and material selection.
• Proficient CAD user (Onshape, SolidWorks, Catia, Creo, Fusion, etc.) with a passion for precise, elegant, scalable design.
• Strong grasp of mechanical engineering fundamentals.
• Strong analytical and problem-solving skills with the tenacity to tackle complex challenges, comfortable performing detailed engineering analyses (FEA, hand calculations, etc.).
• A friendly, collaborative mindset, strong communication skills, and excitement to work hands-on in a dynamic, supportive team environment; design without ego.
• Working understanding of tolerance analysis and GD&Ts.
• Keen attention to detail and craftsmanship, including fit and finish.

Responsibilities

• Create and refine mechanical designs for advanced humanoid robotics, including actuators, manipulators, and integrated systems.
• Own your designs from initial sketches through CAD modeling, prototyping, manufacturing, testing, and deployment.
• Conduct simulations, structural analysis, and performance evaluations to optimize system functionality.
• Generate comprehensive documentation, including CAD drawings, block diagrams, test plans, fabrication, and assembly instructions.
• Interface with external manufacturing partners to optimize designs for manufacturing, testing, and assembly.
• Engage hands-on in the lab, transforming your designs from ideas to production systems through rapid, iterative development cycles.
• Collaborate closely with cross-functional teammates (electrical, software, controls, UX/UI, and industrial designers) to ensure seamless integration across the product.
• Solve fascinating engineering challenges daily, pushing the boundaries of robotics technology.
