Overview

Help us build CloudWalk's ambitious R&D program around humanoid robotics. You'll own the full cycle of developing locomotion and high-level behaviors: design tasks and environments in NVIDIA IsaacLab/Sim/Gym, train policies with RL/IL, validate on simulation and deploy on our physical humanoid robot (Sim2Real).

The Robotics Division
  • We work on embodied AI and autonomous systems across various robotics platforms and applications
  • Full development cycle from simulation environment design in NVIDIA IsaacLab/Sim/Gym to deployment on physical robots
  • São Paulo lab with advanced robotics hardware including humanoids and vending machines
What you\'ll do
  • Invent and build humanoid tasks and environments – from simple flat-ground locomotion to challenging obstacle courses
  • Train and refine policies using RSL-RL, RL-Games, Stable-Baselines3, or similar GPU-parallel RL libraries
  • Explore cutting-edge approaches – reinforcement learning, imitation learning, diffusion policies, and transformer-based approaches for continuous control
  • Close the Sim2Real gap through domain/dynamics randomization, calibration, and staged deployment on the humanoid platform in our lab
  • Integrate with robotics ecosystem – ROS 2 (ros2_control, MoveIt 2) and NVIDIA\'s robotics stack (Isaac ROS, cuRobo/cuMotion, NVBlox)
  • Orchestrate complex behaviors with BehaviorTree.CPP/Groot, and experiment with Isaac GR00T for high-level humanoid skill composition
  • Measure and iterate with reproducible pipelines, dashboards, and design documentation to accelerate R&D cycles
What you\'ll need
  • Solid ML and RL foundations (PPO, SAC, TD3) with hands-on PyTorch experience
  • NVIDIA Isaac ecosystem proficiency – Isaac Sim/Isaac Lab and legacy environments (Isaac Gym, OmniIsaacGymEnvs, Orbit)
  • Strong ROS 2 skills – ros2_control, lifecycle nodes, planning and perception integration
  • Sim2Real expertise – domain randomization, dynamics tuning, and safe hardware deployment
  • Engineering best practices – version control, containerization, reproducibility, and documentation
  • Must be able to work on-site in São Paulo for regular robotics lab sessions with physical robots
Bonus points if you have
  • Legged locomotion experience with humanoid control tasks (Legged Gym, ETH Zurich RSL environments)
  • MuJoCo-based RL workflows (Gymnasium, dm_control, robosuite) for algorithm prototyping and benchmarking
  • Advanced policy architectures – Diffusion/Transformer policies for robotics applications
  • NVIDIA robotics stack – GPU-accelerated planning (cuRobo, cuMotion) and Isaac ROS perception (NVBlox, VSLAM)
  • Real-time systems and mechatronics knowledge (PREEMPT_RT, C++ optimization)
  • Strong portfolio of robotics and ML projects (GitHub repos, demonstrations, research papers)
Work Model
  • Hybrid role – collaborate remotely but spend regular days in our robotics lab
  • Hands-on experimentation with physical humanoid robots is a core part of this job
  • Test, validate, and deploy your simulation work on real hardware in our São Paulo lab
Recruiting Process
  • Challenge: You\'ll receive a technical challenge to demonstrate your skills in robotics, simulation, and machine learning
  • Technical interview
  • Cultural interview

Note: If you are not willing to take an online quiz and demonstrate your technical capabilities with both simulation and physical robotics systems, do not apply.

Diversity and inclusion

We believe in social inclusion, respect, and appreciation of all people. We promote a welcoming work environment, where each CloudWalker can be authentic, regardless of gender, ethnicity, race, religion, sexuality, mobility, disability, or education.
