Simulation Expert (English), 3D Environments and Assets

The work

You will create and configure realistic 3D environments and assets for simulation-based AI training. The work connects real-world objects and instruments with simulated environments so AI systems can learn from accurate physical behavior.

• Build and configure 3D assets and environments in Isaac Sim, Gazebo, MuJoCo, or similar platforms.
• Convert real-world objects and instruments into simulation with accurate geometry, scale, materials, and physical behavior.
• Tune mass, friction, collision properties, and joint dynamics so simulated objects act like their real counterparts.
• Work with scientists and technical subject-matter experts to validate simulated environments.
• Investigate and fix differences between simulated and real-world behavior.

What it pays and takes

• Pay: $60 to $100 per hour.
• Work type: Part-time contract work.
• Location: Open to candidates across the listed countries in the Americas, Europe, Asia, Africa, and the Middle East.
• Language: Professional fluency in English.
• Simulation experience: Hands-on experience with at least one robotics or physics simulation platform, such as Isaac Sim, Gazebo, MuJoCo, Unity, Unreal, or PyBullet.
• Technical background: Experience with 3D modeling, CAD, or environment design.
• Knowledge: Understanding of physics simulation, including rigid-body dynamics, materials, and sensors.
• Work style: Strong collaboration skills with scientific and technical stakeholders, plus close attention to real-world detail.
• AI experience is not required; your simulation and domain knowledge are the focus.
