R&D Engineer – Humanoid Core Technologies

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.

Why this job is exciting

• Join the NEXT team shaping the foundations of the future humanoid robot

• Tackle unsolved challenges like human-level walking, dexterous manipulation, and embodied perception

• Push the boundaries of research into practical, buildable solutions—fast

Responsibilities

• Research, design, and prototype fundamental humanoid technologies including actuation systems, robotic joints, and structural components

• Model and simulate systems to evaluate performance and feasibility

• Design experiments and analyze results to validate hypotheses and inform engineering tradeoffs

• Build and iterate on physical prototypes using machining, rapid fabrication, and embedded systems

• Evaluate academic research and patents for technical inspiration and practical application

• Distill high-concept ideas into actionable engineering workstreams

• Collaborate closely with other domain experts to bridge theory and application

Requirements

• Strong grasp of core engineering principles including math, mechanics, and materials

• Experience designing actuation systems—motors, drivetrains, joints, structures

• Background in Mechanical Engineering, Electrical Engineering, Physics, or similar

• Demonstrated ability to go full-stack in R&D: from concept to prototype to evaluation

• Skilled at assessing feasibility and filtering high-potential ideas from theoretical noise

Nice-to-haves

• Passion for building, tinkering, or technical exploration—professional or personal

• Portfolio of personal or professional projects you’ve designed and built

• Experience developing novel systems from scratch—not just incremental improvements

• Interest in human biomechanics or the nervous system as it relates to robotics

• Strong communication skills and ability to present bold technical concepts

• Appreciation for historical inventors and scientific pioneers

• PhD in a relevant technical field

Location Policy
