Phd Mechanical Engineering Polymer Jobs (NOW HIRING)

We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it’s not.

To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you’re inspired by this, you’ll thrive here. We’ve been at this since 2014 and we’re at the point where the hard problems are behind us and the hard work is in front of us.

NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We’re not demoing it—we’re shipping it. We’re excited to meet you, if this excites you.

If you’ve spent your career working on problems that matter and want to see them actually reach the world, this is that moment. We’re scaling, we’re hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time—safely creating abundance for all.

We work at the intersection of materials science, chemistry, hardware engineering, and manufacturing to invent the foundational technologies that make our robots lighter, stronger, safer, and more capable.

The Materials Science team researches and develops advanced polymers, elastomers, structural adhesives, coatings, and functional materials that directly influence the robot's durability, tactile performance, energy efficiency, and manufacturability. Our work moves rapidly from laboratory research into real robotic systems, partnering closely with mechanical, electrical, manufacturing, and systems engineers.

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.

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.
