First Principles Builder - Experimental Physicist

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 rewarded based on merit.

We believe the best work is done when collaborating and therefore require in-person presence in our office locations.

It’s not quantum physics, but it’s what we like to call ‘rocket science’. To reach human level capabilities for the robot we need to push technologies beyond the status quo and the limits are the laws of physics.

We are seeking an Experimental Physicist to join our Hands Team. This role is ideal for someone driven and inventive who thrives on designing groundbreaking systems from a blank sheet of paper and driving them through to scalable production. You will play a critical role in shaping the functionality, precision, and durability of robotic hands, enabling our robots to reach human level dexterity.

Responsibilities

Translate rough concepts into prototypes then products, iterating quickly based on rigorous experiments and feedback.

Collaborate with mechanical design, electronics design, and cross-functional teams to ensure seamless integration.

Stay current with science literature to push the boundaries of robotic hand capabilities.

Job requirements

Experimental physics PhD.

First-principles thinker who excels at rapid problem-solving and thrives under tight deadlines.

Excellent communication and collaboration skills to work effectively with a demanding, fast-moving team.

Location Policy

We believe the best work is done when collaborating and therefore require in-person presence in our office locations.
