Remote | Simulation Expert — Real-to-Sim 3D Environments & Assets — $60–$150/hour

We are sharing a specialised consulting opportunity for experienced Simulation Experts with strong expertise in robotics and physics simulation, real-to-sim environment development, 3D modelling, CAD, rigid-body dynamics, and physically accurate asset creation to contribute to advanced AI training and simulation initiatives.

Selected professionals will build realistic simulated environments, translate real-world objects and instruments into digital assets, tune physical parameters for behavioural fidelity, and collaborate with scientists and technical experts to validate simulation accuracy. No prior AI experience is required; hands-on simulation and physics expertise is the primary qualification.

Key Responsibilities

3D Asset & Environment Development

• Build and configure 3D assets for realistic simulation environments
• Develop scenes using platforms such as Isaac Sim, Gazebo, MuJoCo, Unity, Unreal, or PyBullet
• Recreate real-world objects, instruments, and operational environments
• Maintain accurate geometry, scale, proportions, and spatial relationships
• Support creation of reusable simulation assets and environment components

Real-to-Sim Translation

• Translate physical objects and environments into simulation-ready representations
• Match material characteristics and expected physical behaviour
• Apply CAD and 3D modelling knowledge to improve asset fidelity
• Identify real-world characteristics that materially affect simulation performance
• Preserve relevant constraints when converting physical systems into virtual environments

Physics & Dynamics Configuration

• Configure mass, friction, collision properties, and related physical parameters
• Tune joint dynamics and mechanical interactions
• Apply knowledge of rigid-body dynamics and material properties
• Support sensor and environmental behaviour where relevant
• Refine physical settings until simulated behaviour aligns with expected real-world outcomes

Simulation Validation & Troubleshooting

• Compare simulated behaviour against real-world reference behaviour
• Identify discrepancies in motion, collisions, materials, or environmental response
• Diagnose configuration and modelling issues affecting simulation accuracy
• Iterate on assets, environments, and physics parameters to improve fidelity
• Document technical issues and corrective actions clearly

Scientific Collaboration & Quality

• Collaborate with scientists and subject-matter experts to validate simulation environments
• Incorporate technical feedback into asset and environment revisions
• Explain modelling assumptions and simulation decisions clearly
• Maintain strong attention to detail across iterative development cycles
• Support consistent quality standards for real-to-sim simulation workflows

Ideal Profile

• Hands-on experience with at least one robotics or physics simulation platform
• Relevant platforms may include Isaac Sim, Gazebo, MuJoCo, Unity, Unreal, PyBullet, or comparable systems
• Strong background in 3D modelling, CAD, or environment design
• Experience creating or adapting assets for simulation
• Strong understanding of rigid-body dynamics
• Familiarity with mass, friction, collision properties, joints, and materials
• Understanding of simulation sensors and environment behaviour is valuable
• Experience translating real-world objects into digital or simulated representations
• Strong troubleshooting skills across simulation and modelling workflows
• Ability to identify sources of mismatch between virtual and physical behaviour
• Strong collaboration skills with scientific and technical stakeholders
• Excellent attention to detail and commitment to real-world fidelity
• Clear written and verbal technical communication skills
• Ability to work independently in a remote environment
• No prior AI-training or model-evaluation experience is required

Engagement Details

• Independent contractor engagement
• Fully remote
• Compensation: $60–$150/hour
• Work will involve real-to-sim environment development, 3D asset creation, physics configuration, validation, and troubleshooting
• Assignments may use Isaac Sim, Gazebo, MuJoCo, Unity, Unreal, PyBullet, CAD, or related modelling tools
• Strong simulation fidelity and practical physics judgement are central to this engagement
• Collaboration may involve scientists, engineers, researchers, and other subject-matter experts
• Project scope, simulation platforms, environments, and technical requirements may evolve depending on project needs
• No prior AI experience is required
• Work must be completed without using confidential or proprietary information belonging to any employer, client, research organisation, institution, or other third party
