About the role
About 1X We’re an AI and robotics company based in San Carlos, 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. That’s why 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 Mechanical Engineer to design, integrate, and validate load-bearing mechanical components used in humanoid robots. This role focuses on mechanical design, systems integration, prototyping, testing, and verification of assemblies that operate under cyclic load, friction, and wear.
Responsibilities Design and execute DoE-driven test programs to characterize component lifetime under realistic load, friction, and environmental conditions Identify key variables (material selection, geometry, duty cycles) and quantify their effect on fatigue and wear life Build and iterate test fixtures; instrument tests and analyze data to extract failure modes and lifetime models Define and maintain V&V plans for mechanical assemblies including acceptance criteria and margin of safety Translate test data and failure analysis into actionable design improvements in collaboration with mechanical and materials teams Support scale-up by ensuring characterization methods and acceptance tests can be applied in production Job
Requirements BS or MS in Mechanical Engineering, Materials Science, or Aerospace Engineering (PhD welcome but not required) Hands-on experience designing and executing structured mechanical test programs, ideally including DoE methodology (Taguchi, full/fractional factorial, RSM) Familiarity with fatigue, wear, creep, or tribology testing of mechanical components Comfortable with test fixture design, instrumentation, and data analysis Experience translating test results into design decisions
