All3 is transforming how buildings are conceived, developed and delivered. We combine AI-powered design with robotic prefabrication and on-site assembly to build custom architecture at the cost and speed of mass production - unlocking even the most complex sites.

We’re currently seeking a Senior/Lead Reinforcement Learning Control Engineer (seniority level adjustable based on candidate expertise) to develop learning-based control systems for dynamic locomanipulation on our large legged robotic platform, Mantis. You’ll design reinforcement learning solutions that integrate tightly the rest of our framework to enable robust locomotion and manipulation in complex, semi-structured construction environments.

Responsibilities:

• Design and train reinforcement learning policies using physically grounded sensor models (LiDAR, cameras, IMUs) to support autonomous locomotion a...
