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 with 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 and manipulation capabilities;
- Integrate learned components within a complex software architecture, ensuring stability and reliability;
- Develop a robust methodology for policy training, tracking improvements, and monitor progress and performance evaluation;
- Develop robust sim-to-real transfer strategies and ensure successful deployment of the policies to the hardware platform;
- Analyse hardware experiments, identify failure modes, and iteratively improve performance and robustness;
- Collaborate closely with perception, state estimation, and software engineers to deliver cohesive, real-time robotic behavior and evolve the robot software architecture design;
- Contribute to the evolution of a unified whole-body control framework for loco-manipulation capabilities;
- This is not a simulation-only research role. The systems you build will run on hardware and must operate reliably under real-world constraints.
