Software Engineer, Robot Character

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

• You'll be on a team with a large set of responsibilities, requiring interaction with hardware, firmware, AI, platforms and production teams, all working towards building the world’s safest and most capable humanoid robot.

• In time, your software will run on 1000's of humanoids performing tasks in diverse environments, globally.

• You’ll be working with a 50+ DoF biped, with hands, all driven by motors we design and manufacture in-house. If this doesn’t excite you then 🤷

Responsibilities

• Own part of the software stack for the robot’s head — including ears, sensors, LEDs, and expressive output.

• Build communication between the head’s embedded systems and the main stack — via SPI, USB, or network protocols.

• Develop services and APIs to expose audio, light, and sensing to ML and behavior teams.

• Work with hardware teams during bring-up and testing — and help turn prototypes into robust, production-ready systems.

• Build tools for debugging, simulation, and integration across real and virtual robots.
