Remote Simulation Expert: Real-to-Sim 3D Environments

micro1; United States; Remote; USD 83,000 - 138,000; Part time

Job summary

micro1 is seeking a Simulation Expert—Real-to-Sim 3D Environments & Assets for a remote contractor engagement focused on advancing AI training through high‑fidelity simulations. You will contribute domain knowledge to how models learn, reason, and perform using real‑world input.

Responsibilities include building and configuring 3D assets, translating real objects into simulation, tuning physics, and collaborating with scientists to validate environmental accuracy across Isaac Sim, Gazebo,

Qualifications

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

Responsibilities

• Build and configure 3D assets and environments in simulation platforms (Isaac Sim, Gazebo, MuJoCo, or similar).
• Translate real-world objects and instruments into simulation, matching geometry, scale, material, and physical behavior
