Manufacturing Electrical Engineer, Joints & Body
About this role
1X is seeking a Manufacturing Electrical Engineer to design and develop the mechanical systems—body, joints, and structural components—that enable their humanoid robot NEO to move safely and reliably in home environments. You'll own hardware from concept through production, solving the mechanical challenges required to build a capable robot at scale.
What you'll do
- Design and release production-ready body, joint, and structural systems meeting performance, reliability, weight, cost, and manufacturability targets
- Develop compact electromechanical joint architectures integrating actuation, bearings, transmissions, sensing, electronics, and structural interfaces
- Build and test prototypes rapidly using physical testing and robot performance data to identify failure modes and drive improvements
- Develop engineering requirements, tolerance analyses, test methods, and validation plans demonstrating hardware performance and reliability
- Support hardware through prototype builds, design validation, new product introduction, and production ramp while resolving issues
- Partner with controls, electrical, manufacturing, reliability, and supply chain teams to develop fully integrated robotic systems
What they're looking for
- Mechanical engineering fundamentals (machine design, structures, mechanisms, materials)
- Mechanical joint design (bearings, transmissions, actuators, fasteners, load paths)
- Design of highly integrated systems under tight mass, volume, and stiffness constraints
- Analytical and first-principles calculation skills
- FEA and tolerance analysis
- CAD, prototyping, and testing methodologies
- Design for Manufacturability (DFM) and Design for Assembly (DFA)
- Cross-functional collaboration and communication
