San Carlos, CA · On-site · Full-time · Posted Jun 17, 2026
About the job
Develop, train, and deploy reinforcement-learning policies that enable NEO humanoid robots to perform manipulation and locomotion tasks reliably in real-world home environments.
What you'll do
- Train and deploy RL policies, and improve sim-to-real transfer for reliable field performance.
- Build training and evaluation infrastructure with benchmarks, regression detection, and links between training metrics and field results.
- Partner with hardware, controls, data, and QA teams to move research into production robot skills.
What they ask for
- Strong Python and/or C++ skills, including experience with large codebases and build tools such as Bazel or equivalent.
- Proficiency with PyTorch for RL policy training and experimentation.
- Hands-on experience with simulation platforms such as Isaac Sim, MuJoCo, or equivalent.
- Demonstrated experience training RL policies for manipulation or locomotion, including addressing the sim-to-real gap on physical hardware.
Nice to have
- Experience with model-based RL, world-model-guided learning, imitation learning, or learning from demonstration.
- Experience deploying RL-trained policies to physical robots in production; background in legged locomotion, dexterous manipulation, or contact-rich control.
