Simulation Expert, Real-to-Sim 3D Environments and Assets

SaidGig; United States; Remote; USD 83,000 - 207,000; Part time

Job summary

SaidGig seeks a remote contract specialist to create high-fidelity 3D simulation environments and assets that accurately reflect real-world objects, instruments, materials, and physics. You will train AI systems by translating real-world fidelity into simulations across Isaac Sim, Gazebo, MuJoCo, Unity, Unreal, or PyBullet.

The role emphasizes collaboration with scientists and domain experts, tuning physical properties, and troubleshooting discrepancies between simulated and real-world behavior.

Qualifications

• Experience with at least one robotics or physics simulation platform.
• Background in 3D modeling or CAD.
• Understanding of physics simulation, including rigid body dynamics, materials, and sensors.
• Strong collaboration with scientists and stakeholders.
• Close attention to detail to match real-world fidelity.

Responsibilities

• Build and configure 3D assets and environments in Isaac Sim, Gazebo, MuJoCo, or similar simulation platforms.
• Translate real-world objects and instruments into simulations, matching geometry, scale, material properties, and physical behavior.
• Collaborate with scientists and subject-matter experts to validate simulated-environment accuracy.
• Tune mass, friction, collision properties, and joint dynamics so simulated objects behave like their real counterparts.
• Troubleshoot differences between simulated and real-world behavior.

This remote contract role focuses on advanced simulation and AI training, and prior AI experience is not required.

Key Responsibilities

• Build and configure 3D assets and environments in Isaac Sim, Gazebo, MuJoCo, or similar simulation platforms.
• Translate real-world objects and instruments into simulations, matching geometry, scale, material properties, and physical behavior.
• Collaborate with scientists and subject-matter experts to validate simulated-environment accuracy.
• Tune mass, friction, collision properties, and joint dynamics so simulated objects behave like their real counterparts.
• Troubleshoot differences between simulated and real-world behavior.

Qualifications

• Hands-on experience with at least one robotics or physics simulation platform, such as Isaac Sim, Gazebo, MuJoCo, Unity, Unreal, or PyBullet.
• Background in 3D modeling, CAD, or environment design.
• Understanding of physics simulation, including rigid body dynamics, materials, and sensors.
• Strong collaboration skills when working with scientific and technical stakeholders.
• Close attention to detail when matching real-world fidelity.

Work Terms

• Remote contract engagement.

Compensation

• $60 to $150 per hour.
