Product Design Engineer, Hands

Since its founding in 2015, 1X has been at the forefront of developing advanced humanoid robots designed for household use. Our mission is to create an abundant supply of labor via safe, intelligent humanoids. As a Product Design Engineer at 1X Technologies, you will design and develop hardware for advanced robotic systems. You will work cross-functionally with mechanical, electrical, firmware, and manufacturing teams to bring concepts from early prototypes through DFM and into production. The role emphasizes robust mechanism design, tight tolerances, reliability, and testability in complex electromechanical assemblies, with particular focus on flex circuits and PCBs. You will own key design decisions, engage directly with suppliers, and produce clear documentation to ensure high-quality products are delivered reliably at scale. Responsibilities Design and develop mechanical components and electromechanical assemblies from concept through production. Proven ability to design and own the full lifecycle for complex multi-layer flex and rigid PCBAs in highly space constrained environments. Create detailed CAD models, drawings, and GD&T for parts and assemblies. Collaborate with electrical and firmware engineers to integrate sensors, actuators, wiring, and PCBs/flex circuits. Lead prototype builds, hands-on assembly, and iterative testing to validate performance. Drive design for manufacturability (DFM/DFA) and cost reduction with manufacturing partners. Plan and execute verification and reliability tests; analyze failures and implement corrective actions. Manage BOMs, ECOs, and product documentation in PLM/PDM systems. Support field issues and continuous improvement with root-cause analysis and fixes.
