1X . About 1X: We’re an AI and robotics company based in Palo Alto, California, on a mission to build a truly abundant society through general-purpose robots capable of performing any kind of work autonomously. We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. We’re focused on developing friendly home robots designed to integrate seamlessly into everyday life. We’re looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we’d be thrilled to hear from you and explore how you might contribute to our journey. Role overview: We are seeking a Senior Mechanical Engineer to lead the design, development, and scaling of critical hardware systems for our humanoid robot, NEO. In this role, you will own mechanical components and assemblies throughout their lifecycle—from concept and prototyping to validation and mass production. You will apply advanced engineering analysis, collaborate across disciplines, and ensure our designs are manufacturable at scale. Your work will directly influence the reliability, safety, and scalability of humanoid robots deployed worldwide. Responsibilities
Lead the design and development of structural components, mechanisms, and assemblies that meet performance and reliability requirements Own the mechanical product lifecycle from concept through validation and production ramp-up Partner with manufacturing and supply chain teams to apply DFM/DFA principles for scalable, cost-effective designs Conduct and oversee mechanical analyses including FEA, thermal, and kinematic studies Collaborate with cross-functional teams to integrate mechanical systems into the full robot architecture Create and maintain design documentation including 3D CAD models, detailed drawings, and specifications Troubleshoot and resolve complex issues during prototyping, testing, and production Mentor junior engineers and foster a culture of innovation and technical rigor Act as a technical authority influencing design decisions and long-term engineering strategy Qualifications
7+ years of mechanical engineering experience with a track record of bringing complex hardware into high-volume production Expertise in CAD modeling and analysis tools (e.g., SolidWorks, CATIA, ANSYS) Strong knowledge of DFM/DFA principles and manufacturing methods including molding, casting, machining, and forging Proven ability to design tight-tolerance, high-reliability mechanical systems Experience conducting advanced mechanical analysis, particularly FEA Hands-on experience with global suppliers, tooling development, and production scaling Strong problem-solving skills and ability to navigate complex design challenges Excellent communication skills and ability to collaborate across disciplines Bachelor’s or Master’s degree in Mechanical Engineering or a related field (PhD a plus) Bonus: Experience in robotics, automotive, consumer electronics, or other complex hardware systems Benefits & Compensation
Health, dental, and vision insurance 401(k) with company match Paid time off and holidays Equal Opportunity Employer
