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.
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 As a Technical Lead in Mechanical Engineering, you will architect and deliver the mechanical systems that define the performance of our humanoid robot's joints and body structures.
This hands-on leadership role combines deep technical execution with system-level ownership, guiding trade-offs and integration challenges.
You will mentor a high-performing team, set engineering standards, and collaborate across disciplines to ensure robust, scalable, and manufacturable solutions.
Responsibilities * Architect, design, and validate mechanical systems including joints, actuators, and structural assemblies * Lead detailed mechanical design work, including 3D CAD, tolerance analysis, materials selection, and structural optimization * Drive system-level trade studies to balance performance, weight, manufacturability, cost, and thermal considerations * Guide integration of mechanical systems with actuators, sensors, electronics, and thermal components * Oversee prototyping, validation, and iterative design improvements based on test data * Establish design standards, processes, and documentation to support scalable product development * Mentor, develop, and inspire a team of mechanical engineers working on critical subsystems * Collaborate closely with manufacturing, electrical, and controls teams to ensure seamless integration * Foster a culture of accountability, technical excellence, and continuous improvement
