Research Engineer / Research Scientist, Robotics and Physical AI

About the Role

This is a hands-on research and engineering role at a small, early-stage AI training data company focused on physical AI and robotics. You will work across the full stack, from learning algorithms and simulation to real-world robot deployment, helping push the frontier of how robots perceive, plan, and act in the physical world.

What You'll Do

• Develop learning systems for robots, including policies, world models, and vision-language-action models.
• Build and maintain simulation environments and evaluation frameworks for robotic tasks.
• Apply and advance computer vision and perception algorithms for autonomous robots.
• Build pipelines connecting simulation and real-world robot deployment, covering real-to-sim and sim-to-real workflows.
• Work directly with robot hardware, sensors, actuators, and embedded systems to prototype and validate capabilities.
• Train and evaluate reinforcement-learning and imitation-learning systems for manipulation, locomotion, or mobile platforms.
• Integrate and experiment with robot platforms to test algorithms in the physical world.
• Create tools and infrastructure that accelerate robotics research and development.
• Collaborate with external robotics companies and research labs on technical problems.

What We're Looking For

• Demonstrated research or engineering experience in robotics and AI, beyond academic experiments alone. New graduates with strong robotics backgrounds are welcome.
• Strong software skills in both C++ and Python.
• Practical experience with deep learning, reinforcement learning, and computer vision.
• Hands-on experience with real-to-sim or sim-to-real robotics workflows.
• Familiarity with simulation platforms such as Isaac Lab, MuJoCo, MJX, or Genesis.
• Experience working with robotics hardware, sensors, embedded systems, and 3D modeling tools.
• Comfort moving fluidly across research, engineering, experimentation, and product development with end-to-end ownership.
• Exposure to modern multimodal AI approaches, such as transformers, diffusion models, world models, vision-language-action models, LLMs, or AI agents, is a plus.
• An individual contributor mindset with motivation to ship in a small, collaborative team.
