Job description
Humanoid robots doing backflips are super cool, but to be useful they need to be able to listen, communicate, and operate in the world. Your role in our organization would be to help make that a reality by developing autonomy for humanoid robots and working to advise manufacturers on their next generation of hardware. ### **What you'll do** * Work hands-on with robots that cost more than most cars * Iterate on software deployed to customer's robots in the real world * Advise humanoid robot manufacturers about sensor placement, hardware interfaces, and operational design * Work on camera-based 3D perception: detection, tracking, gesture and body language understanding, and speaker identification * Improve locomotion for walking safely in public environments * Team up with animators to make the robot's movement, body language, and gestures more fluid and natural ### What we’re looking for * Robotics experience (self-driving cars, drones, humanoids, off-road robotics, or similar) * Experience shipping products into the real world * Strong C++ or Rust experience * Comfortable working with and debugging hardware * Excited to take high ownership of product features ### Technology * We deploy on humanoid robots, for example [Unitree G1](https://www.unitree.com/g1)s upfit with custom hardware. * Our onboard code is written in C++20 and our offboard code is primarily Python 3.14.
