Materials Scientist, Polymers

Your Charter

Develop the advanced coating materials that define the next generation of humanoid robotics.

You will lead a polymer chemistry-driven research and development efforts focused on novel polymer coating materials for load-bearing composites applications. You'll design experiments, characterize materials,, and collaborate with multidisciplinary engineering teams to integrate new materials into production-ready robotic systems. You will connect coating chemistry and polymer fundamental properties to materials performance, including adhesion, friction, abrasion, heat generation, flexibility, fatigue, and others.

Your work will directly shape the mechanical performance, durability, safety, and manufacturability of future 1X robots.

What Does a Successful 1X Team Member Look Like?

• Team members at 1X who thrive here are builders.
• They move fast, own their work completely, and treat time like it's the one thing you can't get back-because it is.
• They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask.
• We push each other to be better, and we do it with honesty and respect.

Successful Chemical Engineers at 1X combine scientific rigor with an engineering mindset. They enjoy experimenting with new materials, solving difficult interdisciplinary challenges, and translating laboratory discoveries into scalable technologies that directly improve robot performance. They are equally comfortable designing experiments, analyzing complex datasets, troubleshooting manufacturing challenges, and collaborating with engineers across multiple disciplines to bring breakthrough materials into production.
