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.

We strive for excellence in all we do, solving some of the hardest problems in robotics with the world’s most talented individuals. Every part of our robots is designed and produced in-house, from motor coils to AI, reflecting our vertically integrated approach. At 1X, you’ll own real projects, be recognized for your achievements, and be rewarded based on merit.

We are seeking a Senior Materials Lab Engineer with deep expertise in polymer based systems, surface science, adhesives, and coatings. This role is ideal for a highly detail oriented, hands-on expert who can independently drive formulation, processing, surface treatment, bonding, and testing of advanced materials, while taking direct ownership of materials lab operations and capabilities.

You will play a critical role in building and operating a high performance materials lab, enabling rapid iteration from raw materials to validated components used in humanoid robots.
